以一种新型钢管旋转机构为研究对象,采用复数矢量法求解了该机构的运动参数。基于ADAMS仿真软件建立了机构的虚拟样机模型,并对该机构进行运动学仿真分析,对比分析了两种条件下其运动规律和状态。分析结果表明,在钢管夹紧阶段,夹杆均为变减速运动;而在旋转阶段,当气缸输入时,机构为变加速的加速转动,当曲柄输入时,机构为匀速转动;气缸在整个运动过程中为正、反向摆动。分析结果为机构的工作参数选择和结构的优化设计提供依据。
Taking a new type of steel pipe rotating mechanism as the research object, the motion parameters of this mechanism were solved by complex vector method. Based on the ADAMS simulation software, a virtual prototyping model of the mechanism is established. The kinematics simulation analysis of the mechanism is carried out. The motion and state of the mechanism are compared and analyzed under two conditions. The results show that the clamp rod is decelerated and decelerated during the clamping of the steel tube. In the rotation phase, when the cylinder is input, the mechanism is accelerating and accelerating. When the crank is input, the mechanism rotates at a constant speed. During the entire movement The process is positive, reverse swing. The results of the analysis provide the basis for the selection of the working parameters and the optimal design of the structure.
