摘　　要：针对势能守恒系统中的关节力矩和阻尼展开分析,依据第二类拉格朗日方程建立动力学模型,并结合仿真进行验证分析.结果表明,关节力矩、弹簧组件中阻尼是影响被动式微低重力模拟系统平衡的关键控制参量.同时,根据系统受激励后的特性提出一种阻尼系数取值的单曲函数定量约束的方法,并进行案例研究,为相关系统的平衡性研究提供定量依据和分析方法.In this paper,the joint torque and damping in the potential energy conservation system were analyzed.The dynamic modeling was established based on the second type of Lagrange equation.Simultaneously,it combined with simulation for validation and analysis.It was concluded that joint torque and damping of spring assemblies were the key control parameters affecting the balance of passive micro-low gravity simulation system.At the same time,a method of quantitative constraint of single curve function with damping coefficient value was determined according to the characteristics of the system after being excited.And a case study was carried out,which provided a quantitative basis and analysis method for the balance research of related systems.
