本文用非线性规划方法对液压挖掘机反铲工作装置进行结构优化设计。通过对各设计要素的综合分析,提出结构优化策略,建又了数学模型。运用FORTRAN语言在IBM-PC微机上编制了结构应力分析和结构优化设计程序。结构最大应力分布规律的分析是优化位置选择和设计合理性评价的依据。现有反铲工作装置的优化结果表明,优化后结构自重明显减轻,应力分布得到改善。作为本文的实际应用,作者对长江挖掘机厂开发产品WY100型进行了工作装置结构优化设计,提供了一组结构参数。
This paper uses nonlinear planning method to optimize the structure of hydraulic excavator backhoe working device. Through comprehensive analysis of various design elements, a structural optimization strategy was proposed and a mathematical model was built. The FORTRAN language is used to program the structural stress analysis and structural optimization design on the IBM-PC microcomputer. The analysis of the structural maximum stress distribution is the basis for optimizing the location selection and design rationality evaluation. The optimization results of the existing backhoe working device indicate that the weight of the structure is significantly reduced and the stress distribution is improved after optimization. As a practical application of this paper, the author optimized the design of the working device structure of the WY100 type product developed by Changjiang excavator factory and provided a set of structural parameters.
