基于ANSYS的港口起重机桁架结构的优化设计

Optimization Design of the Port Crane Truss Structure Based on ANSYS

随着航运的发展,港口起重机也迅速发展。目前,不仅要求起重机有更高的起重量和起升高度,还要求起重机的重量轻、作业空间大。为了减轻自重、简化设计方法,应用ANSYS优化模块提供的一阶优化方法对起重机桁架结构优化,优化后起重机自重减小23.2%,质量明显减小。

Port crane is the guarantee of port industry development At present,it not only requires the crane having a higher weight and hoisting height, besides, the port crane weight must be light and the optimize space is large. This optimization design mainly through reduces the weight of crane truss optimization. ANSYS optimization module provides two optimization methods-zero order and first order, which can deal with most questions. Beam axial stress , the deflection of beam and the stability of the pressure rod as state variables of optimization are to be considered in the optimization. Quality as the objective function, reduced greately after optimization.
