摘　　要：为更好利用双机双质体振动系统,进行自同步运动设计,首先应用拉格朗日方程和传递函数,推导出了振动系统的稳态时的同步响应的表达式,进而推导出了振动系统的稳态相应。对系统进行了数值仿真分析,因为近共振有其特殊的工程意义,定量研究了振动系统在近共振工作状态下,两电机的转速、相位差,及两质体各自的位移与两质体间的相对的位移。最后通过实验验证数值仿真和理论推导的正确性,并给出了相关实际应用实例。To make better use of dual-mass with two motors vibrating system and enhance its design of self-synchronizing motion,firstly,Lagrange equations and transfer function were used to obtain synchronization response expressions of the vibration system. Then,the stable synchronous response expression were obtained. As the near-resonance＇s special engineering significance,the numerical simulation of the self-synchronization vibrating system such as rotational speed,phase difference,the displacement and the relative displacement of the two mass were carried out under sub-resonant working condition. Finally,experiments were done to prove the accuracy of the theoretical analysis and simulations,and relevant practical application examples are given.
