Optimization of leveling mechanism of forest aerial work vehicle
In order to improve the stability and accuracy of the leveling mechanism of the forest aerial work vehicle,this pa-per analyzes the hydraulic cylinder operation of the up-leveling mechanism,establishes a mathematical model for six-varia-ble optimization of the up-leveling mechanism and the down-leveling mechanism,and optimizes the parameters of the level-ing mechanism with the goals of minimizing the force load of the up-leveling oil cylinder,minimizing the extremum values of the adjustment error,and minimizing the range of the adjustment error.The Box-Behnken Design(BBD)is used to optimize the parameters.The experimental results show that the maximum adjustment error of the optimized leveling mechanism is 0.422°,which is reduced by31.3%.The maximum force of the up-leveling hydraulic cylinder was308458 N,which is re-duced by1.8%.The study can provide reference for analyzing the working principles and optimizing the design of the hy-draulic leveling mechanism of the aerial work platform.
