摘要
通过对三轴六自由度振动台系统的机械部分运动学和动力学分析、液压激振系统动态特性分析以及电液伺服控制原理分析,建立了三轴六自由度液压振动台系统的整体模型。仿真结果表明,所得的数学模型能够真实反映该系统的动态特性,其模型频率特性与实际系统相近。
To building the mathematic model of the six degree of freedom shaking table,the kinematical and dynamic modeling problem of the mechanical part of the shaking table was discussed,the dynamic characteristic of the eight servo-hydraulic actuators in the shaking table was analyzed.The six degree of freedom servo control method was analyzed and researched.The mathematic model block of the shaking table was implemented in simulink tool of Matlab.The simulation result shows that this model can effectively reflect...
