摘要: 工程机械轨道吊结构的超差使用, 使得材料利用率较低, 造成经济成本的浪费. 从轨道吊仓主梁结构的力学分析出发, 将主梁重量的优化问题转化成力学约束条件下结构设计参数最优值的求解问题. 将主梁翼缘板、腹板的几何尺寸作为输入参数, 以结构强度、刚度、稳定性作为响应参数, 建立了基于零阶算法的数学优化模型, 通过有限元数值计算求得主梁的优化设计结果. 计算结果表明, 采用新的设计方法可以减轻主梁的重量, 提高材料的使用效率.

关键词: 轨道吊结构, 零阶算法, 优化设计

Abstract: Use of out of tolerance in hanging rail construction in engineering machinery usually causes inadequate utilization of the material and results in waste. Based on a mechanical analysis of the main beam structure in track hanging, a design optimization problem of weight of the girder structure is transformed to a solution of optimal parameters values under mechanical constraints optimal parameters. Using a girder flange plate and the web geometry value as input parameters, structural strength, stiffness, stability as response parameters, an optimization model is established based on a zero-order algorithm. Optimization results of the main beam are obtained by finite element numerical calculation. The results show that the new design method can reduce weight of the main beam and improve the efficient use of materials.

Key words: optimal design, track hanging structure, zero-order algorithm
