摘　　要：为提升钻机工作装置的承载能力,实现快速响应设计,利用虚拟样机技术,对HDL80B型全液压履带式多功能钻机工作装置的结构进行优化研究。首先,采用D-H法对钻机工作装置进行运动学分析,构建运动学方程,并运用MATLAB编程计算获得钻机工作装置的有效工作空间;其次,根据有效工作空间极限工况条件,建立钻机虚拟样机模型,利用ADAMS对工作装置举升结构进行优化设计;最后,通过对举升液压缸受力测试验证优化设计方案。结果表明:将钻机举升结构的支座铰点前移1.2 mm,活塞铰点上移50 mm,支架铰点上移并前移50 mm后,举升油缸的举升力最大值减小了18.7%,与试验结果相符,证实了虚拟样机技术是钻机快速响应优化设计的有效途径。In this article,in order to improve the bearing capacity of the drilling rig’s working device and achieve rapid response,the virtual prototype technology is used to optimize the structure of the HDL80 B full hydraulic crawler multi-functional drilling rig’s working device.Firstly,by means of the D-H method,the kinematic analysis is performed on the working device,and the kinematic equations are constructed;the effective workspace of the working device is worked out with the help of MATLAB.Secondly,the ADAMS software is used to optimize the design of the working device’s lifting structure.Finally,the optimized design scheme is verified by the stress test of the lifting hydraulic cylinder.The results show that the maximum lifting force of the lifting cylinder reduces 18.7%with the optimization of three parameters,such as moving the support hinge point of the rig’s lifting structure forward by 1.2 mm,moving the piston hinge point upward by 50 mm,and moving the bracket hinge point upward and forward by 50 mm.These simulation results are in accordance with the test results.It has proved that the virtual prototype technology is effective for the optimization design of the rig’s rapid response.
