工程机械驾驶模拟器运动平台多体动力学分析

摘要

By applying the dynamical simulation software ADAMS? For mechanical systems,the kinemat-ical and dynamical analyses are first conducted on the motional platform of driving simulators. Then, the virtual prototyping model is established for a 6 - DOF Stewart motional platform. Finally, the variable curves of supporting-leg actuator route and driving force are obtained via simulation. Therefore, the simulation results set a reference to motional platform design.%应用机械系统动力学仿真分析软件ADAMS,对驾驶模拟器运动平台进行了运动学和动力学仿真研究.建立了6自由度Stewart型运动平台的虚拟样机模型,进行了仿真计算,得出支腿作动器行程和驱动力的变化曲线.仿真结果为运动平台的设计提供了依据.
