高卸位装载机可以配套大吨位运输卡车从而加快施工进度,因而具有良好的市场竞争力。通过高卸位装载机工作机构的特性及动作分析,以产生单位掘起力所需转斗缸推力最小为优化目标,建立了工作机构优化设计的数学模型,给出了设计变量,确定了约束条件,对高卸位装载机的六连杆工作机构尺寸进行了优化设计。以Z30E型高卸位轮式装载机为实例,论述了优化过程,并将优化前后的尺寸进行了对比。结果表明:优化后的数据满足平移性、卸料性和自动放平性等要求,且构件间不存在干涉现象。
High unloader can be equipped with large tonnage truck to speed up the construction progress, which has good market competitiveness. Through the analysis of the characteristics and operation of the working mechanism of the high unloader, the optimization objective is to minimize the thrust of the cylinder required to generate the unit lifting force. The mathematical model of the optimal design of the working mechanism is established. The design variables are given and the constraints Conditions, the design of the six-bar working mechanism of high unloader has been optimized. Taking Z30E high unloading wheel loader as an example, the optimization process is discussed and the dimensions before and after optimization are compared. The results show that the optimized data satisfy the requirements of translation, unloading and automatic leveling, and there is no interference between the components.
