颈椎有限元分析模型的应用和进展

有限元分析法(FEA)是一种在工程学中广泛应用的方法,最初应用于模拟并且解决各种工程力学、热学、电磁学等物理问题.其基本原理是将一个由无数个质点组成并且由无限个自由度连续体近似为有限个单元所组成的集体.后来逐渐将有限元方法应用于骨科生物力学的研究,建立了最早的颈椎有限元模型.近年来随着计算机和软件技术突飞猛进,有限元法在颈椎生物力学研究中的利用日益广泛与深入.

Application and progress of the finite element analysis model of cervical vertebrae

Finite element analysis(FEA) is broadly used in engineering,it was initially applied to simulate and solve a variety of engineering mechanics,thermal,electromagnetics,and other physical problems. The principle is a colective to be composed by an infinite number of particles,and an unlimited number of degrees of freedom from the continuum approximation. Brekelmas and Ryblcki firstly applied the finite element method to orthopedic biomechanics research in 1972. The first cervical vertebra finite element model was established in 1982 by Hosey. With the computer and software technology advances in the past 20 years,finite element method in cervical spine biomechanics studies is increased and widespreaded.
