Surface Pressure Simulation Study of Shim Based on Dimensional Analysis
The asbestos-free gasket sealing structure of the rear load plate of an engine was studied,factional pressure simulation calculation of the structural base is performed using a combination of dimensional analysis and finite elements.The Monte Carlo-based VSA software models the assembly of the sealed structure,the sealing dimensions are evaluated for tolerance simulation calculations,gets the extreme value for theoretical sealing dimensions based on virtual assembly,the theoretical sealing dimensions are reconstructed to get a very small dimension model,meshing and post-processing cal-culations are also based on Simlab and Abaqus software,and analyzing the difference in face pressure between the theoret-ical model of the base and the small model with the same bolt preload to optimize the model.
