摘要
设计了一种适应斜坡的新型自动调平平台,可以快速进行位姿调整,确保平台始终处于水平状态。该平台采用3个电动推杆和1个虚固定杆,调节灵活,支撑强度大。通过几何结构推出电动推杆之间的运动关系以及极限角度。基于单片机构建了自动调平平台机电控制系统。通过系统动态特性分析并结合电动推杆响应时间,确立电动推杆速度与加速度模型。实验数据同仿真数据的比较表明,自动调平平台达到预定要求,为进一步的设计和开发工作提供依据。
A new automatic leveling platform was designed adapted to the slope,which can adjust the posture rapidly and ensure its horizontality. It consists of three electric rods and one virtual fixed rod,which ensures its flexible adjustment and large supporting strength. The relationship between electric rods and the limiting angle were derived from the geometry of construction. The mechanical and electrical control system was constructed by MCU. By the analysis of dynamic system characteristics,the velocity and acceleration models of electric rods were given combined with their response time. The comparison between experiment and simulation shows that the automatic leveling platform can meet？predetermined requirements and provide some basis for the deeper design.
