摘　　要：基于虚拟样机技术,在ADAMS软件中建立了新型机器人飞轮弹射装置的动力学分析模型,获得了飞轮转速、摩擦系数等几个影响弹射性能的重要参数,在参数化的基础上进行了设计研究和试验设计。仿真结果与物理样机的试验数据的对比证明了所建立的动力学模型的精确性和设计参数选择的合理性,同时也验证了该装置的弹射稳定性和对偶然条件变化的适应性,为改善物理样机的弹射性能提供了可靠的定量的参考依据。Based on the virtual prototype technology,the dynamic model of an original flywheel ejection mech- anism on a robot has been established in ADAMS.Some key parameters that affect the performance of the mechanism,such as the rotation rate of the wheel and the friction coefficient etc,have been studied by design study and design of experiment(DOE) on the basis of parametric modeling.The coincidence between the sim- ulation and the test results of the physical prototype validates the precision of the dynamic model and the ratio'- nality of the design parameters.The result reveals the ejection stability and the adaptability to randomicity, and also some reliable quantitative references are offered for ameliorating the design of the prototype.
