【摘要】 本文运用非线性弹性线理论,提出了脊柱侧弯形状记忆合金棒矫形系统的数学力学模型,并进行了力学分析,侧弯脊柱用一小变形大挠度的弹性线来表示,形状记忆合金棒的记忆性质则通过与脊柱侧弯形状和程度有关的初始形变来表示。利用这种矫形系统模型,对用形状记忆合金棒矫正侧弯的效果和矫形力进行了分析。更多还原

【Abstract】 <ABSTRACT>In this paper a mathematical and mechanical model of orthopedic systemof scoliosis with shape memory alloy rods is described as well as its mech-anical analysis. The scoliotic spine is represented by an anisotropic elasticawith small deformation and large deflection, and memory properties of shapememory alloy rods expressed by means of initial deformation related to degreeand configuration of scoliotic spine. By using this model of orthopedicsystem, the effect and corrective forces of shape memory alloy rods areanalysed for correction of scoliosis,更多还原
