针对目前已运用的悬臂式运煤列车防冻液喷洒装置不能升降的问题,设计了一种可升降的悬臂式喷洒装置,以便能够有效地喷洒各类规格车厢。在UG中建立了喷洒装置的三维模型,并将其导入到ADAMS软件中进行了运动仿真。仿真结果验证了结构设计的合理性和可行性,并为进一步的动力学分析以及优化设计奠定了基础。 In view of the problem that the antifreeze spray device of the cantilevered coal train can not be raised and lowered at present, a kind of cantilever spray device which can be raised and lowered is designed so as to effectively spray various types of cars. In UG, a three-dimensional model of the spraying device was built and imported into the ADAMS software for motion simulation. The simulation results verify the rationality and feasibility of the structural design and lay a foundation for further dynamic analysis and optimization design.
