对玻璃纤维复合材料圆柱螺旋弹簧的加工和弯曲力学性能进行了研究。通过大量探索性试验确定了复合材料弹簧的成型工艺流程，讨论了弹簧的加工工艺及结构参数对其弯曲回弹力、回复率及拉伸性能等的影响规律。研究结果表明，复合材料弹簧的弯曲力学性能与弹簧内径、纤维束的捻度、股数及直径等有直接关系，并受弯曲、回复时间的影响，可以根据需要设计弹簧的工艺和结构参数。
This paper is mainly about the study on the processing and mechanical performance of glass-fiber composite springs. The processing parameters of cylindroid spiral springs were confirmed on the basis of a large number of experiments. Influence of processing technology and structure parameters of the composite spring on bending resilience, bending restoration rate and tensile property was also tested and analysed.The experimental results indicate that bending mechanical performance of the composite spring is directly associated with the inside diameter of the spring, and the diameter, twist and number of fiber bundles. The bending restoration rate of the composite spring is under the influence of bending time and restoration time. The processing and structure parameters can be regulated according to specific conditions.
