| 摘 要： | 基于Newton Euler法对三向六自由度(6 PSS)并联地震模拟器进行了动力学分析，分析了地震模拟器运动平台与各构件运动参量之间的关系；考虑重力与惯性力的影响，推导了并联机构杆件和运动平台动力学方程，并消去各构件之间的内力，建立了机构整体动力学方程；基于动力学模型进行动平台各驱动力的数值仿真.结果表明，6-PSS并联机构适用于地震模拟器，所建立的动力学模型能够作为其精确控制的数学模型.

| Abstract: | Based on Newton-Euler method,the research on the dynamics of a 6-PSS parallel earthquake simulator was presented.The relations of motion parameters between the platform and other poles were deduced.Newton-Euler equations were educed for every poles and the platform respectively with thinking about the effect of the gravity and inertia force of all components.After all of forces between poles and between platform and other poles being removed,equations for the inverse dynamics of the holistic parallel mechan... |
