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LMS AMESim建立了电振动台正弦振动控制仪模型；通过多学科系统仿真软件LMS Virtual.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仿真，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 platform 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 Motion. 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 virtual vibration test system was implemented. Finally

a virtual sine vibration test for a box &thin specimen was performed by using the proposed system. Test results show that the virtual vibration testing platform based on the electrical and mechanical coupling modeling method can provide test environments for test analysis and virtual vibration test because it considers the coupling effect of the testpiece and the electrical vibration table.
