随着铁路运输事业的发展与机车车辆的现代化,需要生产大量的性能优良而质量可靠的减振、缓冲等装置所用的弹簧元件。这就要求具备相应的测试设备。目前,机车车辆工业系统使用的弹簧测试设备,大都是五十年代前的陈旧产品(如Birmingham型、五七型、PC89型等)。这些弹簧试验机存在着测力计精度低、机械结构复杂和操作不便等缺点。为了改变这种状 With the development of railway transportation and the modernization of rolling stock, a large number of spring elements for damping, buffering and other devices with excellent performance and good quality need to be manufactured. This requires the appropriate test equipment. At present, the spring testing equipment used in industrial systems of locomotive and rolling stock are mostly old products (such as Birmingham type, 57 type and PC89 type) until the 1950s. These spring testers have the disadvantages of low dynamometer, complicated mechanical structure and inconvenient operation. In order to change this shape
