The stability and credibility of the mechanical system virtual prototyping simulation software is enhanced . based on windows nt platform , the practicable software of mechanical system virtual prototyping which include preprocessing , solver and postprocessing are studied . the practicable version of mechanical system virtual prototyping ( msvp ) is developed 在基于windowsnt平台的pc机上，对机械系统虚拟样机仿真软件的前处理、求解器以及后处理各组件统一进行了实用化研究，开发了机械系统虚拟样机（ mechanicalsystemvirtualprototyping ，简称msvp ）仿真软件的实用化版本；通过几个典型实例对msvp进行了初步验证，并与adams仿真结果进行了对比分析，结果表明： msvp操作方便，运行稳定，结果正确，初步达到了实用化的要求。
And the best scheme among them has been proposed . in the last , with design opt of ansys , assigning roof plate ' s and base plate ' s thickness as design variables , making them meet the constraints of displacement of roof plate and base plate , and assigning the maximum stress of the structure as the goal function , the pile - boots structure has been optimized 最后利用ansys自带的优化求解器designopt ，以对桩靴结构强度和变形影响较大的顶板和底板厚度为设计变量，在满足重要部件?顶板和底板竖向位移的约束条件下，把结构的最大等效应力设为目标函数，采用一阶优化方法，对桩靴结构进行了优化设计，并得到了最优解。
Using the formula of taylor , the dissertation disperses the mathematics model as the classical form of wave - arithmetic and displays the spread process of heat . according to the principle of object - oriented theory combined with the sample method , the software is divided into three parts : pre - analysis groupware , analysis groupware and after - groupware 在研究系统仿真技术的基础上，以面向对象程序设计方法与原形法相结合的方法，将仿真系统划分为前处理组件、求解器组件和后处理组件，以sun公司的java技术和java3d软件包设计系统的应用程序。
