摘要

In this paper, the influence of high speed train vibration on the human lumbar spine is studied by three dimensional finite element method. The point cloud data of the human lumbar vertebrae are acquired by the arm type flexible point coordinate digital measuring instrument. Then it is imported into the Hypermesh software for model reconstruction and mesh generation. The finite element models of L1~L5 in human lumbar spine are created and MSC Nastran software is used to analyse the model and vibration response of the whole lumbar spine model. Results show that the resonance frequency of the human lumber spine mainly concentrates in low frequency phase. The vibration is mainly bending and torsion. Under given high speed train vibration excitation conditions, the vibration amplitude of L4~L5 segment is larger, which is the weak link of lumbar spine. This high amplitude vibration will significantly increase the load bearing capacity of the lower lumbar spine. The analysis of the finite element dynamic characteristics of high speed train passengers helps study the influence on passenger lumbar spine structure and its action principle in rail transit vibration environment. It helps to improve the treatment and prevent lumbar disease, and it has important significance in the design optimization of the passenger seat.
