基于MSC/PATRAN的飞机结构强度静力试验数据实时跟踪与处理系统开发

Development of Test Data Tracking, Analyzing and Processing System for Aircraft Structural Strength Based on MSC/PATRAN Platform

在Windows环境下,以MSC/PATRAN为平台,利用平台提供的二次开发语言PCL(Patran Command Language),并结合C++语言,通过客户化、增设特定的命令和窗体等技术开发了飞机结构强度静力试验数据实时跟踪与处理系统TestDTAS(Test Data Tracking,Analyzing and Processing System)。在结构试验进行中,TestDTAS可以实时地监测结构试验件中应力和位移的变化情况,并与理论分析结果进行对比,而在试验结束后,TestDTAS可以进行试验数据回放和分析,从而将试验与理论分析有机的结合在一起,对结构静力试验和结构设计有很高的实用价值。

Under windows operation system, a system for test data tracking, analyzing and processing of aircraft structural strength （TestDTAS） is developed on MSC/PATRAN platform. The work is performed with adding special commands and windows by using the PCL language provided by MSC/PATRAN and C＋＋ language. During the test of aircraft structural strength, the TestDTAS is able to timely monitor and display the structure stresses and displacements which also can be compared with the theoretical analysis results in the same time, After the test, the test data will be repeated and analyzed for linearity by using TestDTAS. Thus combination with structural test and structural analysis is very practical to structural test and structural design.
