摘　　要：针对滑移装载机举升铲斗调平问题,设计了滑移装载机铲斗自动调平系统。基于AMESim建立分流阀、顺序阀和调平系统总体仿真模型,仿真分析了分流阀分流特性、顺序阀卸荷情况和初始状态下的举升调平性能,并基于遗传算法对动臂小腔油液回T阻尼、进铲斗大腔阻尼和铲斗小腔油液回T阻尼通径进行了参数优化。结果表明:初始状态下举升调平性能较差,动臂和铲斗速度比为2.4;优化后铲斗自动调平性能得到提高,动臂和铲斗速度比调整为2.1,优化后的铲斗倾角范围为-2°—3°。Aiming at the leveling problem of the lifting bucket of a skid steer loader,an automatic leveling system for the lifting bucket of the skid steer loader was designed,and its lifting automatic leveling principle was given.Based on AMESim,the overall simulation models of the diversion valve,unloading valve,and leveling system were established.The diversion characteristics of the diversion valve were simulated and analyzed,and the unloading range of the unloading valve was verified.The lifting leveling performance in the initial state was simulated and analyzed.Based on genetic algorithm,the parameters of the damping diameter of the small chamber oil return T of the boom,the damping diameter of the large chamber inlet of the bucket,and the damping diameter of the small chamber oil return T of the bucket were optimized.The research results showed that the lifting leveling performance was poor in the initial state,and the speed ratio of the boom and bucket was 2.4;The automatic leveling performance of the optimized bucket has been improved,with a boom to bucket speed ratio of 2.1 and an optimized bucket tilt angle range of-2°—3°.
