摘　　要：多股簧是由钢索(通常由3～14股、1～3层、0.4～3mm的碳素弹簧钢丝缠绕而成)卷制而成的圆柱螺旋弹簧。与单股弹簧相比,多股簧具有更好的强度及独特的吸振、减振效果,因而可广泛应用于振动设备、高精度台面和要求很平稳的运输车辆等,以取代传统的单股弹簧和橡胶弹簧。本文综述了多股簧特性、用途及研究现状,介绍了本课题组开发的多股簧数控加工机床,解决了多股簧加工过程中的张力精确控制、回弹等难题,为将多股簧应用在汽车及摩托车减振器上提供了性价比高的解决方案。A stranded-wire helical spring is a cylindrical helical spring rolled by a strand, which usually consists of 3 to 14 carbon steel wires of 0.4 to 3 mm in radius. Compared with a conventional single helical spring, it has a unique characteristic in better damping and vibration reduction. Therefore, it can replace the traditional single spring or rubber spring, and is widely used in vibratory equipments, such as vibration sieves, anti-vibration breakers, high precision table-boards and steady transport vehicles. This paper reviews the characteristics, applications, research status of stranded-wire helical springs. In addition, a CNC machine which solves the problems of accurate control of force and springback during the manufacture is presented. The research and development of the machine provides a highly cost-effective solution to apply the stranded-wire helical spring to automotives or motorcycle shock absorbers.
