【摘要】 介绍旋挖钻机变幅机构的主流结构形式及其工作原理,并借助Pro/E建立变幅机构的三维模型,再导入ADAMS建立动力学仿真模型。在ADAMS虚拟环境中,对变幅机构两组变幅油缸在不同运动顺序下的举升力分别进行仿真,给出两组变幅油缸举升力的仿真曲线,并分析仿真结果,得出对旋挖钻机变幅机构设计具有指导性的一些结论。更多还原

【Abstract】 Introduces the main current structure pattern of parallelogram system of rotary drilling rig and its working principle.The 3D model of parallelogram system is established in Pro/E.Then it’s transformed to a dynamics simulation model in the ADAMS environment.With the ADAMS tools the lifting forces of the boom parallelogram cylinder and the mast cylinder are simulated in different motion orders,then the simulation curves are generated.By analyzing the results some conclusions which are useful to the parallelogram system design of rotary drilling rig are gotten.更多还原
