Summary: From artillery total construction model sets out, it is a foundation in order to assemble tie collect and team of outfit recipe Cheng, built the gun that frame of total construction design and parameter turn gun total construction model, realized artillery thoroughly the parameter of total construction changes a design, for artillery of total construction change model design, seriation is designed and optimized a design to provide quick and feasible means. As the development of CAD technology, for can apace builds product model, express design intention of the architect thoroughly in the round, put forward parameter to change the method of the design. Parameter changes a design more accord with the thought with design of the concept in apt and contemporary CAD and collateral design, those who be a spare parts change model the design provided effective means. However, in the design process of artillery, design to can realize quick artillery prototype, often adopt the total construction plan of some mature artillery that make type directly, extract alone rarely among them the design program of specific spare parts, like some 37 boat prepare Chinese medicine by roasting it in a panbig gun, some 23 boat prepare Chinese medicine by roasting it in a pan and some 57 tall artillery piece used identical automatic machine to devise plan: Some 130 cannon, some 122 cannon and some 152 gun-howitzer also used similar total construction to devise plan. Existing parameter changes design method to the spare parts change model the design is quite effective, to total construction change model design support is very limited however, especially in the assembly of the product the model is finished hind, of hardware design dimension again metabolic general cannot assure automatically in front the assembly that assembles a model size consistency, the effectiveness that also cannot make sure the artillery in front assembles a model automatically at the same time and physical kind can assemble a gender of prepare Chinese medicine by roasting it in a panbig gun, often bring about artillery fictitious assemble a model break down and the assembly of artillery physics prototype is interfered, restricted gun badly of total construction change directly model design efficiency. For this, the article from artillery total construction model sets out, it is a foundation in order to assemble tie collect and team of outfit recipe Cheng, built the gun that frame of total construction design and parameter turn gun total construction model, realized artillery thoroughly the parameter of total construction changes a design, for artillery of total construction change model design, seriation is designed and optimized a design to provide quick and feasible means. The parameter that 1 parameter changes the compose of structural model to build a part changed system of existing and mechanical CAD to provide the design method that spare parts parameter changes commonly, wait like I-DEAS, Pro/E, UG, Solidword and AutoCAD. This literary grace changes design platform for spare parts parameter with I-DEAS software, the architect can be abided by " draw an external form first, size is decided after " design principle, according to the design the imagination builds the three-dimensional model of gun part directly, join geometry to design intent regulation, the geometry that checks a part and dimension tie are complete. Use I-DEAS parameter to change a function to decide gun part designs parameter and parameter set, can change parameter gun part model to stock at the same time in sharing list. When be used afresh, the architect needs to extract parameter to turn gun part model from inside sharing list only, gift new part designs parameter, use dimension drive mechanism, can build requires gun part model automatically. Structural parameter changed existing mechanical CAD system to be offerred commonly assemble exercise module, use at observing the spare parts assembles a case, check spare parts interference, computational quality character and animation demonstrate to assemble program. The tree that assembles administrative levels to be able to use a convert will describe, father is assembled contain child assemble the adduction with the spare parts, child assemble a bag to contain those who have a part to cite or smaller assembly, formed assemble hierarchy. Use what I-DEAS offers to assemble module, the assembly that can define artillery is restrained (Assembly Constrains) , wait like Face-To-Face and Line-To-Line, the assembly that examines cannon restrains completeness, what build on fire artillery piece thereby is fictitious assemble a model. However, the assembly that general and mechanical CAD offers the model is imperfectly, offerred assembly is restrained is the fixed position tie between the spare parts merely, cannot convey the assembly between different spare parts dimension concerns in coordination, and assemble dimension concern to be formed jointly by the design dimension that is in different spare parts to go up commonly in coordination, having mechanical CAD is unified kind do not offer corresponding cooperate withing to define a method, the measure that can adopt labour of choose and employ persons to contrast in spare parts design phase only comes one by one cooperates with, the likelihood is brought about assemble the phenomenon that the model breaks down and interferes each other. Because this article uses outfit recipe Cheng (the concept of Assemblye Quations) , spare parts and spare parts between all assembly dimension concerns in coordination the definition matchs equation to install, the many outfit recipe Cheng that cooperate with match the outfit that comprises a product equation team. Assembling design phase, assembled tie and outfit recipe Cheng to will make complete gun jointly fictitious assemble a model. Assemble a tie built I-DEAS to offer cite between the method that establishs permanent fixed position to assemble a tie, if certain cites dimensional position produces change, the other that is kept in fixed position to assemble a tie cites will revise automatically. Normally assemble a tie to include Face-To-Face and Line-To-Line two sort. It is OK to install those who match equation to establish the method that uses process designing expression is formed jointly by the design dimension that is in different spare parts to go up, exist between the spare parts assemble dimension to concern in coordination. The architect can be used outside hang a program to build what dimension assembles between the spare parts to concern in coordination directly, assemble equation team namely. Same, if a quotative design dimension produces change, existence assembles what dimension concerns in coordination to cite will revise automatically generate. Assembling what the definition of equation uses is the expression of similar D1=d3, D2=d4. The article will exist to assemble dimension to cooperate with the drive relation definition between the relation, hardware design dimension that is in different spare parts to go up is dimension correlation drive. Graph 1 structure parameter changes a design to realize a process to pursue 2 parameter change structure of model of artillery barrel structure to design parameter to be in complete artillery is fictitious in assembling a model, the partial design parameter of the spare parts is independent drive, because partial design parameter gets the assembles equation team limitation of artillery, in artillery design process, cannot become independent drive, mirror the assembly between the spare parts partly namely dimension cooperates with the relation, spare parts that is in the existence on different spare parts to concern in coordination designs parameter, it is the design parameter of jackknife, choose among them a parameter can. Accordingly, the article will be in complete artillery is fictitious the design parameter that in assembling a model, can change independently, the definition designs parameter for the structure of artillery. Structural design parameter and complete product are fictitious assembled a model to will form complete parameter to turn artillery structure model. The structural parameter of 2 artillery changes design construction parameter to change a design is to show the premise that using identical or similar structure or artillery form falls, parameter of design of the structure in assembling a model through turning structure or gun to complete parameter assigns afresh, use mechanism of dimension correlation drive, the structure that creates contented structure or products plan demand automatically or product assemble the design method of the model, its basic implementation course is shown 1 times like the graph. In total construction change model when the prototype of design or series artillery is designed, the parameter that the extraction in designing personnel to convert structural model warehouse from the parameter of artillery directly needs turns structure or artillery model, v structure designs parameter form, gift the design worth with structural design new parameter, use mechanism of dimension correlation drive, build requires structure or artillery model automatically, can realize total construction thereby change model the archetypal design of design and series artillery. Graph 2 turn model of artillery barrel structure for parameter namely, can offer quick structure to change for artillery barrel model design. The article offerred 3 conclusion the parameter of total construction turns gun design method, to use overall design directly the plan provided a kind of quick means. Total construction parameter turns the gun that is based on I-DEAS it is feasible that the design proves in practice, to shortening the design of artillery is periodic, implementation artillery is overall of the structure change model design, seriation design and the port with optimize a design to have very principal.
