Chassis design and test of crawler photovoltaic panel maintenance work vehicle

针对土质湿滑、坡度大且障碍物多等应用场景,现有光伏板检修作业车行驶困难、适应性差等问题,开发了一种适合在丘陵、湿地环境条件下行驶的履带式光伏板检修作业车。以作业车底盘为研究对象,利用理论与试验相结合的方法对行驶稳定性、通过性和越障性进行研究。通过理论计算发现,检修作业车在坡道横向行驶极限坡度角为30.5°,坡道纵向上坡极限坡度角为49.6°,攀越最高垂直壁为390 mm。通过目标样车实地测试,试验结果与仿真结果最大误差不超过8.3%,满足工程设计精度要求,为光伏板检修作业车的设计与应用提供了实践指导。

In order to solve the problems of difficult driving and poor adaptability of the existing photovoltaic panel maintenance operation vehicle in the application scenarios such as slippery soil,large slope and many obstacles,a crawler photovoltaic panel maintenance operation vehicle suitable for driving in hilly and wetland environmental conditions was developed.Through theoretical calculation,it is found that the ultimate slope angle of the overhaul operation vehicle in the lateral driving of the ramp is 30.5°,the ultimate slope angle of the longitudinal uphill slope of the ramp is 49.6°,and the highest vertical wall climbed is 390 mm.Through the field test of the target prototype,the maximum error between the test results and the simulation results is not more than 8.3%,which meets the accuracy requirements of engineering design,and provides practical guidance for the design and application of photovoltaic panel maintenance vehicles.
