摘要
应用有限元接触分析方法,研究钢轨接头螺栓螺纹旋合长度对螺栓强度的影响.通过改变钢轨接头螺栓和螺母的螺纹旋合长度,并进行相应的接触有限元分析,定量研究钢轨接头螺栓内部的应力分布,为实现钢轨螺栓螺母的轻量化,降低螺栓和螺母的制造成本提供理论依据.
By using finite element contact analysis method,the influence of the length of thread engagement on the strength of rail bolt was analyzed.Through changing the length of thread engagement of rail bolt and carrying on the finite element contact simulations,the quantitative research of stress distribution within the rail bolt was completed.And through which,a theoretical foundation for the realization of lightweight of rail bolts and nuts,and the reduction of manufacture costs was
