摘　　要：利用三维建模软件Pro/ENGINEER建立油阻尼断路器整体模型;将模型导入到多体动力学仿真软件ADAMS中,修改各个零件的属性,对各个零件添加相应的运动副约束,对模型添加碰撞接触力、合闸力、油阻尼力、弹簧力、电磁吸力、柔性连接力等载荷,分析了在不同倍数电流情况下的铁心速度、铁心受力以及动作时间等多种动态特性;此外,还对分离模型中不能解决的铁心位置问题进行了分析,得到了不同电流下断路器分断时的铁心位置;通过将整体模型仿真结果、分离模型的仿真结果和实验结果进行对比,证明了整体模型比分离模型仿真结果更接近实际情况,减小了仿真的误差,而且整体模型的仿真能够提供分离模型不能提供的数据。这为油阻尼断路器的研究开发提供了新的设计手段。An integrated model of circuit breaker with oil dashpot is established by using 3D modeling software Pro/ENGINEER.By implanting the model into the multi-body dynamics simulation software ADAMS and modifying materials properties,adding motion constraints corresponding to each part of the model,adding contact force,closing force,oil damping force,spring force,electromagnetic force and flexible connection force to the model,the core speed,core force,action time and more dynamic characteristics have been studied under different current.In addition,the problem of core position which cannot be solved in the separation model is analyzed under different current.Comparing the simulation results in integrated model and separation model with the experimental results,shows that the result of the integrated model is much more similar with the actual condition and the simulation error has been reduced,and the simulation of the integrated model can provide the data that the separation model can not provide.This provides a new design method for the research and development of circuit breaker with oil dashpot.
