动车转向架检测线多功能小车运动分析及仿真

Motion Analysis and Simulation of Multifunctional Crane of the Bogie Test Line

多功能小车是检修生产线系统上的关键设备,主要完成动车转向架的运输、多级升降和水平旋转等检修工艺步骤,具有承载大、动作定位精度高、工作可靠等优点。文中建立了多功能小车三维实体模型,分析了多功能小车运动部分结构和传动链,设定了多功能小车的一些主要技术参数。最后使用多体动力学仿真软件ADAMS对多功能小车建立仿真模型并设置相关约束,在预定载荷下进行动力学仿真。仿真结果验证了机构设计的合理性并达到了设计要求的运行指标。

Muhifunction crane is the key equipment of the motor bogie overhaul production line systems, which is mainly used to complete the transport of motor bogie, multi-stage lifting and horizontal rotation overhaul process steps, with carrying large, action high positioning accuracy, reliable work and other technical requirements. Firstly, a three-dimensional solid model was established to analyze the structure and the drive chain of multifunetion crane＇s moving parts. Main technical parameters of multifunction crane were set. Finally muhi-body dynamics simulation software adams was used to establish simulation models for muhifunetion crane and set the related constraints. At a predetermined load dynamic simulation was conducted. Simulation results verified the rationality of mechanism design and operation indicators meet the design requirements.
