According to driving torque optimization problem of new concept rocket launch platform based on connecting rod mechanism,a dynamic model of the launch platform was established.
针对基于连杆机构的新型火箭发射平台驱动力矩优化问题,建立了该新型火箭发射平台动力学模型,利用ADAMS软件,进行了无平衡机和有平衡机情况下系统动力学仿真,通过对仿真结果进行分析,比较有平衡机和无平衡机两种情况下系统机构在运动状态的受力状况,并用参数化优化设计方法、以驱动力矩最小为目标,利用ADAMS软件对平衡机的参数进行了优化设计,显著降低了机构的驱动力矩。
