以MCYY2000移动式煤炭采样机采样装置为研究对象,为提高其控制精度,降低在采样过程中采样臂颤振,在ADAMS软件中建立采样臂的虚拟样机,仿真分析在最大工作半径工况下采样臂的运动学特性与动力学特性,求取采样头的位移、速度、加速度以及液压缸铰点与采样臂关键铰点的受力等运行参数,为后续进行运动控制,提高其工作准确性等提供依据。
In order to improve the control precision and reduce the sampling arm chatter vibration in the sampling process of MCYY2000 mobile coal sampling device, a virtual prototype of the sampling arm was established in ADAMS software. The simulation analysis was conducted under the maximum working radius Arm kinematic and dynamic characteristics of the sample head to find the displacement, velocity, acceleration and hydraulic cylinder hinge point and the sampling arm of the key hinge point and other operating parameters of the force for the follow-up motion control to improve their work accuracy Provide evidence.
