针对无杆飞机牵引车液压系统元件布置过于分散的缺点,利用将部分液压元部件集成的方法对系统进行优化,并对优化后的液压系统进行评价。结果表明优化后的牵引车性能良好,成本降低。 Aiming at the disadvantage that the components of the hydraulic system of the towing aircraft are too scattered, the system is optimized by integrating some hydraulic components and the optimized hydraulic system is evaluated. The results show that the optimized tractor performance is good and the cost is reduced.
