摘要
运用PCL语言,实现了对固体推进剂应力松弛试验测量值异常数据的处理,用最小二乘法拟合了推进剂松弛模量的Prony级数,运用迭代求解的方法生成了Burgers模型的四个参数,最后绘制了Patran风格的用户界面,实现了数据处理系统与Patran平台的无缝集成。
This paper designs a program in PCL, in which propellant-relaxation-test data are dealt with. Considering the oddity numbers produced in the test, the Prony series of propellant are generated. Based on that, the four parameters of Burgers model are solved. At last, an interface of MSC. Patran style is built, making the system integerated to the software seamlessly.
