基于LS-DYNA的T型电梯导轨残余应力研究
|
摘要
在T型电梯导轨的三点压弯校直理论基础上,研究T型电梯导轨的校直变形规律。利用SolidWorks三维软件进行几何建模,导入ANSYS/LS-DYNA进行有限元仿真,得出T型电梯导轨在校直后的残余应力分布规律。再通过调整压头、支点的位置,探讨压头的行程变化和支点之间的跨距对应力、应变和校直质量的影响,为T型电梯导轨的校直方法研究提供一定的理论依据。
According to the three-point bending and straightening theory of the T-type elevator guide rail, the straightening deformation rule of the guide rail is studied. Using SolidWorks three-dimensional software for geometric modeling, importing ANSYS/LS-DYNA for finite element simulation, the residual stress distribution rule of T-shaped elevator guide rails during straightening is obtained. And by adjusting the position of the indenter and the fulcrum, the influence of the change of the stroke of the indenter and the span between the fulcrum on the residual stress and the quality of the alignment is explored,which provides a theoretical basis for the research on the straightening method of the T-type elevator guide rail.
