多股螺旋弹簧制造中的回弹量研究（本科毕业论文设计）
摘 要
多股螺旋弹簧（简称多股簧）由于其有良好的机械强度、吸振、减振作用、寿命和安全性较高而成为航空发动机和自动武器等产品中是非常重要的一个部件。但是由于目前国内对于多股簧的理论研究非常少，造成在多股簧的生产加工中，废品率非常高、制造成本较高，而生产效率很低，且生产质量不稳定。其中多股簧在绕制过程中的回弹量研究就是其中很重要的一部分。
本文利用材料力学、弹塑性力学结合实际生产加工中弹簧采用的生产加工工艺条件,对单股簧的回弹量进行比较详尽全面的理论分析，并推导了单股簧的回弹量计算公式，从而为以后多股簧的回弹量研究提供一定的理论分析基础。
本次论文在研究多股簧的相关背景知识，和生产加工的工艺条件。然后结合力学分析对单股弹簧进行力学分析，并根据其变形阶段分为了弹性和塑性变形两个阶段，根据变形种类分为弯曲和扭转变形。对相应的各种情况做了详细的变形分析。综合各种变形情况下各自对加工参数的影响联立方程求解出单股簧加工中这些工艺参数的计算公式。为以后做多股簧的回弹量研究提供了理论基础。采用 borland C++ builder编制了简单的计算软件，并实验验证了理论计算的精确度。

ABSTRACT
Strand wires helical spring as they have very good mechanical strength, absorber, vibration-absorption effect,high life and safety become a very important component as an aviation engines and automatic weapons, and other products.However,due to the lack of theoritical research for strand-wire helical spring,there is high defective index,high manufacturing cost and low productive effect ,unstable production quality in the spring production. One part of the research is the spring-back study in the spring of winding.
By plasto-elasticity and spring processing conditions,the paper do a comprehensive theoritical analysis,and work out the calculation formula for a single stranded spring.This provides a theoritical analysis basis for strand wires helical spring in the future.
The paper summarizes the background and processing conditions of strand-wire helical spring.With the plasto-elasticity analysis on single stranded spring, the deformation section is divided into two sections,elasticity and plasticity; the deformation categories is divided into two kinds,bending deflection and tortional deflection.And detailed deformation analysis corresponding to the deformation conditions has been done.Integration of their respective effect on the processing parameters,Calculation formula for a single stranded spring is solved by the simultaneous equations.And provide a theoritical analysis basis for strand wires helical spring.For the digital and automation of spring production, a calculation software is worked out by using borland C++.Finally,the experimental tests this theoretical caltulation accuracy.Experimental results show that the accuracy of the theoretical formula is high.
