摘要:针对用振动台进行飞行器振动环境试验时存在试验周期长、耗费高及易发生过试验或欠试验等问题,采用虚拟现实技术建立了飞行器虚拟振动试验平台。采用系统仿真软件LMSAMESim建立了电振动台正弦振动控制仪模型;通过多学科系统伤真软件LMSVirtual.Lab建立了振动台的多体系统动力学模型,进行了振动台多体动力学模型与电磁作动系统模型的机电联合仿真;实现了振动控制系统、电磁作动系统、振动台与试件机械系统的闭环伤真,构建了飞行器虚拟振动试验平台。利用该虚拟振动试验平台系统进行了盒式试件的正弦振动试验。结果表明,采用机电耦合建模方法构建的虚拟振动试验平台综合考虑了试件、振动台机械系统、控制系统及电气系统的耦合效应,可为飞行器的试前分析和虚拟振动试验提供试验环境。

Abstract: As the spacecraft vibration testing based on a shaking table has some defects, such as long time cycle, high cost, easy to produce over-testing and under-testing, a virtual vibration testing plat-form was built based on virtual reality technology. A sine vibration controller model of the electrical vibration table was built by system simulation software LMS AMESim and a multi-body model for the vibration table was established based on the multi-body simulation software LMS Virtual. Lab Mo-tion. Furthermore, the model of electromagnetic actuator in the vibration testing system was realized using the simulation software LMS AMESim, and the co-simulation of vibration testing system was carried out by uniting the multi-body model and LMS AMESim model. In combination of the vibration control system, electromagnetic actuation system and shaking table test mechanical system, the whole
