The Simulation Research Of Reverse Buffer On Light Truck

Coupling plays an important role in the mechanical transmission, It is used to linkthe two shaft of different organizations (driving shaft and driven shaft) to rotate tocommon transmission torque of mechanical parts. The design of the actual researchtopics, Designed to reverse the buffer can be used in an automotive powertrain, Play amajor role in buffering deceleration by twisting. Achieved effectively reduce drivelinetorsional rigidity purpose, By reducing its torsional rigidity to protect the engine.The thesis’s content mainly includes three aspects:first of all,according to firstdesign drawings of the staff for modeling, and then get the simplified finite elementmodel of reverse buffer. And then do the simulation analysis of the model. The maincontents include the strength analysis and modal analysis. Obtain the relevant propertiesof the product, such as the most dangerous point, the inherent characteristics andvibration mode,etc. According to the simulation results,other designers of project teamoptimize the buffer. And according to the optimized new dimension to do the secondarybuffer model. And then do simulation analysis, again get its stress state and the modalparameters. And the compares the twokinds of design of before and after optimizationto verify its carrying capacity.The finite element analysis using the Workbench. First of all, loading the originaldesigned part in CATIA to Workbench, and try to run in Workbench,and then get thesimplified model scheme; And then simplifying the model of the original design, onceagain into the finite element analysis software. Analysis will contact pair of Workbenchand function combination of rotation, and the success of the process in reverse bufferrubber and the contact between input and output shaft force, has a certain credibilityanalysis results are obtained.
