道路养护车上料机构仿真研究

摘要

During the design stage of the loading mechanism,the motion simulation was carried out,and a kinetic model of cable lifting was proposed based on ADAMS/Cable.The motion trajectory of the working parts were analyzed in the process of simulation,verifying the structural rationality of the mechanism.The simulation failure of multi-body contact in ADAMS was solved by the constraints of the working parts movement.The displacement,speed,acceleration and cable force of the working parts were attained,which provided the basis for analyzing the work characteristics of the mechanism and improved the efficiency of loading mechanism design.%在养护车上料机构设计阶段对其进行运动仿真，利用 ADAMS/Cable 建立了道路养护车上料机构的动力学模型。通过对工作部件的运动进行约束，解决了 ADAMS 中多体接触时仿真容易失败的问题，顺利得到机构工作部件的位移、速度、加速度和绳索受力的数据，及其危险工况的发生时间，为进一步分析优化该机构的工作特性提供了基础，并且能提高上料机构的设计效率。
