| 摘 要： | 以QTZ630塔式起重机为研究对象,利用ANSYS有限元软件建立有限元模型,重点讨论了在自重载荷、风载荷等静载荷影响下,受起吊及卸载工况冲击载荷作用时塔机整体结构的变形、应力随时间的响应情况。对于研究塔式起重机的动态特性及避免材料破坏而造成事故具有实际意义。

| Abstract: | Taking QTZ630 tower crane as research object,this paper established its finite element modal with ANSYS.The time response of the deformation and stress of the tower's whole structure was emphatically discussed under loading and unloading conditions with gravity loads and wind load influence.The conclusion of the study has practical significance for reseaching the dynamic characteristics of the tower crane and avoiding accidents caused by material damage. |
