虚拟环境下大口径火炮故障预测技术——虚拟预测环境

Fault Prediction Technology for Large Caliber Gun Under Virtual Environment:Virtual Prediction Environment

综合考虑状态力学特性、工况监测参数、传统专家经验的融合和推理技术,是解决大口径火炮维修保障任务的紧迫问题。运用ADAMS/FEA模块将ADAMS软件计算的作用力按照载荷工况输入到有限元分析程序中。通过ADAMS/FEA接口,将有限元分析数据返回到ADAMS软件中,实现了虚拟样机在虚拟环境下多柔体的仿真、分析和计算。该技术为大口径火炮故障预测提供了理论依据和数据支持。

Solving emergent problems of large caliber gun maintenance support are to comprehensively consider mixing and inference technology such as state mechanics characteristics, working state monitoring parameters and conventional expert experience. Using ADAMS/FEA module, acting force calculated by ADAMS software program is input FEA program according to load working state. By means of ADAMS/FEA interface, FEA analysis data is returned to ADAMS software. As such, simulation, analysis and calculation of multiple flexible bodies virtual prototype under virtual environment are realized. The technology provided theoretical support of basic data for fault prediction of large caliber gun.
