摘要
为减少某型号8吨反铲液压挖掘机工作装置的制造成本,在综合考虑多种典型工况、理论挖掘力、静态强度的基础上对反铲液压挖掘机工作装置进行了轻量化设计。分析与计算了挖掘机工作装置在五种典型工况下的挖掘力,并通过有限元分析软件ANSYS中对工作装置进行了静力学强度分析。采用ANSYS、MATLAB与导重法相结合的方法对挖掘机工作装置进行了优化设计,最终优化结果表明在满足材料许用应力的情况下工作装置质量减少了21%,降低了工作装置的生产成本。
In order to reduce the manufacturing cost of an 8 ton backhoe hydraulic excavator working device,a lightweight design of the excavator working device is carried out on the basis of comprehensive consideration of a variety of typical working conditions,theoretical excavation force and static strength. The excavation force of the excavator working device under five typical working conditions is analyzed and calculated,and the static strength of the working device is analyzed by the finite element analysis software ANSYS. The method of combining ANSYS,MATLAB and the Weight-Guide method is used to optimize the working device of excavator,and the final optimization results show that the weight of the working device is reduced by 21% and the production cost of the working device is reduced when the allowable stress of the material is met.
