地铁车内扶手强度校核工况分析和仿真计算

Strength Check Performance Analysis and FEM Calculation of Subway Handrails

为研究地铁车内不同类型扶手的强度校核工况,基于人体尺寸标准及人体力学理论,考虑地铁车辆在运营过程中的线路情况,确定典型扶手的静强度及疲劳强度的校核工况.采用有限元仿真分析方法进行扶手强度校核,并验证方案的可行性.

In order to study the strength calculating load cases of different kinds of subway handrails, the static and fatigue strengths of the handrails are calculated and determined based on the standard of GB10000-1988 and biomechanics with the consideration of subway line conditions. Furthermore, the strength of the handrails is checked by FEM, and the feasibility of the method is verified.
