1、I摘要弹簧试验机专门用来测量弹簧性能的仪器。弹簧制造出来后要经过精密的性能测试才可以在实际工作中应用，弹簧很大部分在一般机械和轨道车辆等重要部件中使用。在轨道车辆中使用的弹簧要是没有通过严格精密的测试，一旦性能没有达标，会使车辆在行驶过程中发生严重的交通事故，给人民的生命和财产安全带来巨大的损失。本文设计主要为弹簧试验机液压系统的的设计、机身外形和直线传动滚动导轨的选型设计。设计的弹簧试验机主要用于最大压力 100kN、最大直径 300mm、最大长度 850mm 范围内螺旋弹簧的测定。由液压系统实现对测试速度的便捷控制，测试不同压力下弹簧高度值、横向偏移量，以进行弹簧疲劳试验，也可以通过手控操
2、作实现对钢板简单的机械挤压。液压系统下压行程具有快进与工进几种速度，能快进提高工作效率，工进速度可任意调节，提高机器实用性。本文的机械设计主要在 SolidWorks2014 的制图软件中进行，设计出来的机器要求自动化程度高，运行稳定、可靠。关键词： 弹簧试验机；液压系统；直线传动IIIIIABSTRCATAn instrument used to measure the performance of a spring. After the manufacture of the spring to go through the precision of the performance test
3、 can be applied in practical work, most of the spring in general machinery and rail vehicles and other important components in the use of. In the use of rail vehicles in the spring when the test precision did not pass, once the performance is not up to the standard, the vehicle will make the serious
4、 traffic accident happened in the process of running, has brought huge losses to peoples lives and property safety.The design of this paper is mainly about the design of the hydraulic system of the spring testing machine, the shape of the fuselage and the design of the linear transmission rolling gu
5、ide. The design of the spring testing machine is mainly used for the maximum pressure 100kN, maximum diameter of 300mm, the maximum length of 850mm within the scope of the measurement of the coil spring. By the hydraulic system to achieve convenient control of test speed, test under different pressu
6、re spring height, lateral offset, for spring fatigue test of steel plate, also can realize the simple mechanical extrusion through manual operation. Under the pressure of the hydraulic system with fast forward and the work of a few kinds of speed, fast forward to improve work efficiency, work speed
7、can be adjusted to improve the practicality of the machine. In this paper, the mechanical design of the main SolidWorks2014 mapping software, the design of the machine requires a high degree of automation, stable and reliable operation.Key words: spring testing machine; hydraulic system; linear tran
