摘　　要：为了保证飞机除冰车在臂架变幅过程中,工作平台始终与水平面保持平行,采用静液压调平与平行四边形机构相组合的调平方式,同时对静液压调平系统进行数学建模及机构优化。以工作平台相对于水平面的偏差角度为优化目标,以下调平液压缸的铰点位置以及两个液压缸缸筒面积之比为设计变量,利用MATLAB遗传算法求解。优化结果表明,优化后的调平偏差角最大值为-0.8°,优化比例达到49%,调平性能得到明显优化。To ensure that the working platform of aircraft deicing vehicle remains parallel to the horizontal plane in the process of boom luffing, a leveling method combining hydrostatic leveling and parallelogram mechanism is adopted. At the same time, mathematical modeling and mechanism optimization of hydrostatic leveling system are carried out. Taking deviation angle of working platform relative to horizontal plane as optimization objective, and hinge position of downleveling hydraulic cylinder and ratio of cylinder barrel area of the two hydraulic cylinders as design variables, it is solved by MATLAB genetic algorithm. The optimization results show that the maximum value of optimized leveling deviation angle is-0.8 °, the optimization ratio reaches 49%, and the leveling performance is significantly optimized.
