大型起竖装备起竖机构布置形式对比研究

摘要
大型起竖装备的前置直推式机构和后置直推式机构对起竖装备的性能有着不同的影响。利用ADAMS和AMEsim软件建立起竖机构力学性能的联合仿真平台,对举升过程做动态仿真。由仿真结果进行对比得知:前置直推式起竖机构与后置直推式的机构相比,响应速度快、工作周期短、活塞行程小、液压缸的摆角小,但系统压力和驱动力较大,整个系统的工作状态为不稳定状态。通过两种起竖机构的对比结果,为大型起竖装备起竖机构的选择提供了参考。
The front direct push mechanism and the rear direct push mechanism of large erecting equipment have different effects on the performance of erecting equipment. This paper uses ADAMS and AMEsim software to establish a co-simulation platform for the mechanical properties of the erection mechanism, and dynamically simulates the lifting process.Comparing the simulation results, the erection mechanism of the front direct push type has a faster response speed, a shorter working cycle, a smaller piston stroke, and a smaller swing angle of the hydraulic cylinder than the erection mechanism of the rear direct push type, but the system pressure and the driving force is large, and the working state of the entire system is unstable. The comparison of the two erection mechanisms provides a reference for the selection of the erection mechanism in large erecting equipment.
