摘要
为模拟高速列车驱动装置的多轴随机振动环境,提出一种能沉浮、侧滚、横摆三自由度振动模拟的三自由度电液振动环境模拟台的设计方案.通过建立振动环境模拟台运动学反解模型,并基于adams软件建立动力学仿真模型,对振动环境模拟台的附加运动及逆向动力学进行分析,最后根据振动环境模拟台的无阻尼动力学方程对系统不同姿态下的固有频率进行分析。分析结果表明:该振动环境模拟台运动精度和固有频率能够满足试验要求,为各作动器选型、拉杆及振动梁优化设计提供依据。
One kind of design scheme for 3D Electro-hydraulic vibration environmental simulation stand is proposed to simulate the random vibration environment of high speed train＇s drive Device. Based on the inverse kinematic model of simulation stand, the dynamics simulation model is built on the platform of the ADAMS, additional movement and inverse dynamics analysis of vibration environmental simulation stand are conduct. Finally the inherent frequency of the simulation stand is studied based on the no-damp kinetic equation. The results show that the motion accuracy and inherent frequency of this vibration environmental simulation stand could satisfy the test requirement. It provides the basis for the selection of actuator and optimization design of pull rod and vibrating beam.
