摘要
梨形截面伸缩吊臂具有当前最先进的截面形式,探讨其轻量化设计方法具有重要意义。在通用有限元软件ANSYS Workbench中建立梨形截面伸缩吊臂的参数化模型,在Static Structural模块完成梨形截面伸缩吊臂强度、刚度分析,利用Linear Buckling模块对梨形截面伸缩吊臂整体稳定性进行探讨。在此基础上,将吊臂强度、刚度及整体稳定性作为约束条件,构建以自重最轻为目标的优化设计模型。借助GDO模块响应面技术实现梨形截面伸缩吊臂的优化。这种轻量化设计方法对今后大吨位铁路起重机的设计具有实际的指导与借鉴作用。
The anti-buckling behavior has led to the development of the telescopic boom from box section to pear -shaped cross-section,so the boom lightweight design work needs to consider not only the strength but also a certain requirements of the stabili -ty.Pear-shaped cross-section telescopic boom has the most advanced form of section ,and its lightweight design exploration has much more importance .Establishes the parametric model of the telescopic boom in the general finite element software ANSYS Workbench .The strength and stiffness of the boom are completed in the Static Structural module and the overall stability is ex -plored in the Linear Buckling module .Then the optimization design module is built with the constraints of strength ,stiffness,over-all stability and the objective of lightest weight .The optimization work was achieved by the response surface technology in the GDO module.The method of lightweight design gives a practical guidance and reference for the future design of large -tonnage rail-way crane .
