摘要
用自制的演示仪器,容易说明弹簧的形变主要是由金属丝的扭转引起的.借助于量纲分析及螺旋弹簧变形机理的二维模型。
A new self-made apparatus is used to demonstrate that spring deformation is mainly caused by torsion of wire. The spiral spring deformation formula and coefficient of stiffness are directly derived by dimensional analysis and two-dimensional model of spiral spring deformation mechanism.
