机械系统运动仿真中用户输入函数的求解和实现

在对机械系统运动仿真中用户输入函数进行分析研究的基础上，采用Ｃ＋＋语言和面向对象的方法实现了对用户数据文件中函数的自动查找、识别、存储、分析、读取直至调用的功能。采用适合的数据结构存储函数信息，并用一内嵌式程序语言解释器对其进行分析。建立了实现这些用户输入函数功能的通用组件（函数库），供求解计算时方便调用。分别采用笔者开发的仿真软件和ＡＤＡＭＳ软件对实例进行了仿真分析，二者结果基本吻合。

Solution and Realization of Users-Input Functions During Motion Simulation of Mechanical System

It is important and difficult to solve the problem of users input functions during the motion simulation of mechanical system. The users input functions and their characteristics are described. Searching, identifying, saving, analyzing and getting the functions are realized automatically, and a general model including the functions is developed on the basis of the language C and the object oriented modeling method. In this model, a proper data structure is developed to store the information of functions, and a tiny programming language interpreter is designed and embedded to analyze the functions. The calculation of the functions is provided by this model. A typical example for the motion simulation of a manipulator is given and the results are compared with ADAMS to show that the method is feasible. So the motion simulation can be realized by the software system.
