【摘要】：悬臂端的静刚度通常对带悬臂的门式起重机轻量化设计起控制作用。这种情形下,使用常规的仅以各结构件截面尺寸为设计变量的优化方法,轻量化的效果通常不理想。以32t-26m带悬臂的L型门式起重机为例,针对悬臂端的静刚度不足问题,在主梁截面尺寸为优化参数的基础上,增加主梁和支腿连接宽度作为优化设计变量,并提出一种非对称的支腿结构形式。分析结果表明:采用改变支腿的连接宽度或支腿形状的方法,门机的质量分别减少10.47%和12.85%,可明显提高轻量化的效果。
[Abstract]:The static stiffness of the cantilever end usually controls the lightweight design of the gantry crane with cantilever. In this case, the conventional optimization method with only the cross-section size of each structure as the design variable is used. The effect of lightweight is usually not ideal. Taking the L-type gantry crane with cantilever 32t-26m as an example, aiming at the problem of insufficient static stiffness at the cantilever end, the section size of the main beam is an optimized parameter. Adding the connection width of the main beam and the supporting leg as the optimum design variable, and proposing a kind of asymmetric supporting leg structure form. The analysis results show that the method of changing the connection width or the shape of the supporting leg is adopted. The quality of door crane is reduced by 10.47% and 12.85, respectively, which can obviously improve the effect of lightweight.
