摘　　要：基于装载机整体式发动机罩的自动开启需求,设计了一款基于四连杆机构和扭杆弹簧的发动机罩重力平衡装置,解决了原滚轮式扭杆弹簧重力平衡装置存在的问题;在ADAMS软件中建立该装置机构的参数化模型,以扭杆弹簧预扭转角最小为目标,对机构进行了尺寸参数优化;为了获得更均衡的机构性能,在单目标优化的基础上对机构参数进行了优化后处理,最终的优化结果满足最初的设计要求并通过了试验验证。Based on automatic opening of the integral engine hood in a loader it has to design a new hood with a gravity balance device as based on a four bar linkage and torque-bar spring to have eliminated problems existing in the original hood.The way is to construct a data model for the mechanism in an ADAMS software,which is aimed at minimal pre-turning rotation angle of the torque spring before optimizing the mechanism's dimensions data after single unit's optimization for a better balanced mechanical function,and results of the optimizations can meet the initial design requirements,thus passing the proof test.
