摘要
分析了弯曲回弹应力应变变化过程 ,推导了矩形截面杆回弹弯矩、回弹曲率的计算公式 (1 4 )、(1 1 ) ;发现经典纯弯曲理论确定回弹弯矩的方法与公式 (1 4 )
This paper analyzes the changing process of the stress and the strain of bending re spring,infers calculating formula (14)、(11) of re spring curve and re springing bending moment for beams of section of rectangle,and finds the more theory tolerance between the formula (14) and the method determining re spring bending moment according to the classically pure bending theory.
