可控软启动齿轮传动系统的稳定运行能够有效保障船用电机启动的安全运行。为提高可变刚度对可控软启动齿轮传动性能的效果，以齿轮传动系统作为研究对象，应用ADAMS仿真软件建立刚柔耦合模型，并进行动力学特性分析。获得各级传动角速度曲线，将刚性体与柔性体角速度曲线进行对比，可以看出柔性化后曲线产生明显波动，刚柔耦合仿真结果与理论计算误差范围在5%以内，验证了模型的正确性。齿轮时变啮合刚度对传动系统的影响较大，通过改变不同的啮合刚度，齿轮啮合力波动明显，局部陡峭曲线的出现频率增加。
Controlled soft start device for the stable operation of the gear transmission system can effectively ensure the safe operation of the ship start.In order to improve the variable stiffness on the properties of controllable soft start gearing effect, in gear transmission system as the research object, using the ADAMS simulation software to establish the coupled model, and dynamic characteristics analysis. The angular velocity curves are obtained, by comparing the curves of rigid body and flexible body, the flexible curve fluctuates significantly. Time-varying meshing stiffness of gear has vice influence on the transmission system, the changes of stiffness show that gear meshing force fluctuation obviously, besides, the frequency of emergence of local steep curve increased. The results enable the data to be used for decreasing virbration and the optimal design.
