摘要: 采用将较长表达式分割并用变量替换的递归循环方法,编制了相应的符号处理程序模块,将由Mathematica得到的公式化简并转化成FORTRAN格式的源代码.通过算例说明该程序是正确、有效且可靠的.

Abstract: The formula deduced with Mathematica for dynamic modeling of flexible multibody systems is not simple enough and well formatted for programming.In order to code these formula into our system program of dynamic analysis for flexible multibody systems, a program module is developed to simplify and recode the formula using a recursion method.A test has been conducted which shows that the symbolic processing module is correct, effective and robust.

Key words: flexible multibody system, dynamic modeling, symbolic deducing
