摘要
为保证大型化的造船门机安全稳定地正常工作,依据金属结构的强度、刚度、稳定性的原则进行设计。通过有限元法对所设计的造船门机进行分析,获得结构在各种实际工况下的应力及变形情况。并在此基础上进行了改进,降低了最大应力,减小了结构自身质量,为大型化造船门机结构的设计提供了依据。
For the sake of working safely and stable,large-scale shipbuilding gantry crane was designed based on the principle of metal structure：3S,Strength,Stiffness,Stability.The detailed finite element analytical computation was successfully carried out on this structure,the stress and strain distribution of this structure were obtained under various actual operations.On the basis of it,the structural improvement was carried out,The result of design indicated that the stress was evident and the weight was lighten.This laid a foundation for the structure design of large-scale shipbuilding gantry crane.
