针对现有的三级气缸悬臂机构由于刚度不够引起的挠度较大的问题,提出了一种全新的设计方案,通过在多级气缸的第一级气缸前端安装升降液压缸,在第一级气缸后端加装铰接结构的设计,改变整条悬臂的俯仰角,对悬臂的挠度进行补偿。利用ANSYS和MATLAB软件进行了仿真和数据拟合,并对现有的激光测距仪的测量方式进行了改进,优化了该装置的电气控制系统。最终通过结构上和控制系统的优化,进一步缩小了该装置的挠度。 Aiming at the problem of large deflection of existing three-stage cylinder cantilever mechanism due to insufficient rigidity, a new design scheme is proposed. By installing a lift cylinder at the front end of the first stage cylinder of the multi-stage cylinder, Rear-end design of the hinge structure to change the pitch angle of the entire cantilever to compensate for the deflection of the cantilever. The simulation and data fitting were carried out by ANSYS and MATLAB software. The existing measurement methods of laser range finder were improved and the electrical control system of the device was optimized. Finally, the structure and control system optimization, to further reduce the deflection of the device.
