摘要：根据信息熵理论,模糊变量可以转化成为等效的随机变量。因此,一个多体动力学中模糊机构运动学问题可以利用随机机构运动模拟方法求解;利用ADAMS二次开发功能,采用Matlab语言编制Monte Carlo求解和绘图程序,建立了ADAMS多体动力学中模糊机构运动求解模块。最后的算例表明了所论方法的有效性。
Based on the information entropy,the fuzzy variables can be transformed into the equivalent random variables.Consequently,the kinematic problems of the confusion mechanism in multi-body dynamics can be efficiently solved by using the random mechanismal motion simulation.With the help of the secondary development functions of ADAMS,the model of solving the confusion mechanism motion in multi-body dynamics with ADAMS is built by the Matlab programming language,which is used for the solving and drawing pregrams of Monte Carlo Method.Numerical results show that the feasibility of the method in this paper.
