Sensitivity Analysis of Crank-slider Mechanism of Mechanical Press Based on Virtual Prototype

In order to study the effect of the size of crank on the press force of a mechanical press,the sensitivity analysis on a crank-slider mechanism of a mechanical press is studied and the factors of the press force are found out.First,the geometric model is built according to mechanical press's physical prototype,and the initial conditions of simulation analysis are determined.According to the initial conditions the parametric virtual prototyping of the mechanical press is determined in ADAMS,simulation analysis is carried out.The factors that have significant influence on press force are found out by design study.This study provides an analysis method for variable optimization for crank-slider mechanism design.
