Embodiment Construction
[0022] The simulation analysis method of the present invention will be further described below in conjunction with the accompanying drawings.
[0023] Taking static analysis as an example, the specific steps are as follows figure 1 Shown:
[0024] 1. Use PRO / ENGINEER for precise 3D geometric modeling
[0025] Use PRO / ENGINEER for precise modeling and assemble the model, such as figure 2 shown. image 3 is an exploded representation of the parts of the assembly drawing, showing that the model accurately simulates the actual physical model.
[0026] 2. Enter the PRO / ENGINEER sub-module PRO / MECHANICA, and impose physical constraints and various loads.
[0027] Set the physical characteristics of the model, various loads, boundary conditions and contact areas.
[0028] 3. Set the stiffness of the bearing
[0029] In various crankshaft lathes, there are various bearings, and the rigidity performance of each bearing is also different. Therefore, it should be set differently ...
