全液压自动猫道举升系统运动学分析

摘要

全液压自动猫道举升系统在举升钻具过程中要充分保证其运行的平稳性，以降低冲击载荷和整个举升滑道的振动。根据全液压自动猫道模型，将举升系统进行简化，建立其机构运动简图；应用 MATLAB 软件求解运动学方程并进行线性拟合，得到举升滑道的空间位姿变化曲线；应用 Ad-ams 软件对举升系统进行运动学分析，得到举升滑道倾角变化曲线、位移曲线和速度曲线，验证了其设计的可行性。%In the process of lifting drilling tools,it is very important to ensure the stability of oper-ation of the lifting system of full hydraulic automatic catwalks,in order to reduce the impact load and the oscillation of lifting ramp.According to the full hydraulic automatic catwalks model,the lifting system is simplified,and its mechanism motion diagram is established.Using MATLAB software to solve the kinematics equation and get space posture change curve of lifting ramp by linear fitting,kinematics analysis was executed on the lifting system by using the Adams soft-ware,and the curves of lifting ramp angle and displacement curve and speed curve were obtained, and the feasibility of the design was verified.
