Study On Parameterized Design And Numerical Assembly Of Dedicated Computers

In the different types of dedicated computers,most majority of the components are versatileand interchangeable, and those varying components are quite similar in structure and size.Therefore, parts of dedicated computers can be classified into various modules by their differentfunctions, and the varying components can be parameterized. Establish a unitstore, quote thecomponents when designing new type computers, which can shorten the design cycle, reduceworkload and improve design efficiency.By imposing modular design ideas and feature-based modeling method, thethree-dimensional solid models of dedicated computers are built with Pro/E software. Carry outthe secondary development of Pro/E with Pro/Toolkit(the development tool of Pro/E system)andVisual C++ 6.0 programming language. Compile the Pro/Toolkit user applications, createuser-defined menus and user dialogs, realize the parametric design of components of dedicatedcomputers chassis, through quoting the part models and of transferring the parameters.Pro/E possess a strong function of assembly. Find the assembly order by remove law, layoutthe assembly path in accordance with the assembly principles, and then assemble thecomponents of dedicated computer chassis into overall model. After completing the preassembly,check the interference of the chassis parts. Finally simulate the actual assembly process of theproduct on computer by assembly simulation, check the rationality of assembly sequence andassembly path, feedback the problems to the designers and correcte it.The operating environment of dedicated computers is more severe than that of regularcomputers, so we have to simulate the temperature field of dedicated computers, which verifieswhether the designed chassis can meet the design requirements. Importing the established Pro/Ethree-dimensional model into ANSYS analysis software Through the interface module betweenPro/E and ANSYS, by selecting the grid cell, setting the parameters of material properties,dividing grids, imposing load and boundary conditions, post-processing and other operations, getthe temperature contours of the holistic chassis and the key components. By comparison with theexperimental results, verify the feasibility of thermal simulation with ANSYS software.
