摘要
针对星轮式爬升机构稳定性指标r值较大,影响运行稳定这一问题,提出了一种曲柄摇杆式爬楼梯装置。研究了曲柄摇杆机构杆长对运动轨迹的影响,并对装置进行设计,使其r值减小了22%;应用SolidWorks软件对装置进行建模及爬楼过程仿真,得到其空载和施加载荷时的运行轨迹图,确定了方案的可行性;并进行样机测试,验证了装置的运行稳定性。研究结果说明,曲柄摇杆式爬楼梯装置的设计思路是正确的,对于开发类似产品有借鉴意义。
Aiming at the problem that the stability index r value of star-wheel climbing mechanism is large,which affects the operation stability,a kind of crank rocker climbing stair device is proposed.The influence of crank rocker mechanism rod length on trajectory is studied.The structure size of the crank rocker type climbing mechanism is designed while the r is reduced by 22%.The modeling of crank rocker type climbing stair device and the simulation of the process of climbing stairs are carried out by SolidWorks software,the motion trajectory diagram when the vehicle is unloaded and loaded is obtained,the feasibility of the scheme is determined.A prototype test is carried out to verify the stable operation of the device.The results show that the design idea of crank-rocker stair climbing device is correct,and it has reference significance for developing similar products.
