摘　　要：为了研究曲柄和连杆的尺寸对压力机的压紧力大小的影响,针对某压力机的曲柄滑块机构进行敏感度分析,找出对压紧力影响较大的因素。首先根据压力机的物理样机抽象出几何模型,由压力机的实际参数确定仿真分析的初始条件。根据初始条件在ADAMS中建立压力机的参数化虚拟样机,并进行仿真分析。经过设计研究找出对滑块压紧力影响较大的因素,为压力机的压紧力优化提供设计变量选择的依据。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.
