【摘要】 在对大倾角带式输送机机架空间框架进行有限元分析的基础上,把型钢的截面尺寸作为设计变量,把整机重量作为目标函数,根据满应力准则确立设计变量的约束条件,通过求解从而得到了大型型钢结构的最佳设计方案。更多还原

【Abstract】 In this paper the crosssections of steel shapes are used as design variables,thegeneral weight of conveyor frame is used as objective function,and restrictive conditions of the de-sign panametcrs,are esteblished based on the“full-stressed rule”.Optimum design result ofsteel-shape structure of high-slope belt-conveyor is obfained.更多还原
