弹簧试验机是专门测试弹簧的仪器。弹簧生产出来后，在使用之前，要通过严格的测试才能投入使用，
Spring tester is a special instrument for testing springs. After the spring is produced, it must pass strict test before it can be put into use.
因为弹簧多数是使用在机械、车辆上面的主要部件，如车辆上的弹簧，如果装在车上的弹簧没有经过严格的测试，随便装在车辆上面使用，性能没有达到要求，那就容易造成非常严重的后果；
Because most of the springs are the main components used on machinery and vehicles, such as the springs on vehicles. If the springs installed on vehicles have not undergone rigorous testing, they can be used casually on vehicles, and their performance does not meet the requirements, it is easy to cause very serious consequences.
而再如用于避震的弹簧，因为性能的衰退，使得车辆失去平衡，容易造成交通事故。由此总结出弹簧试验机的主要作用是对拉簧、压簧、碟簧、塔簧、板簧、卡簧、片弹簧、复合弹簧、气弹簧、模具弹簧、异性弹簧等精密弹簧的拉力、压力、位移、刚度等强度试验和分析。
Another example is the spring used for shock absorber, because of the deterioration of its performance, the vehicle loses its balance and is liable to cause traffic accidents. It is concluded that the main function of spring testing machine is to test and analyze the tension, pressure, displacement and stiffness of precision springs, such as tension spring, compression spring, disc spring, tower spring, leaf spring, clamp spring, leaf spring, composite spring, air spring, die spring and heterosexual spring.
弹簧试验机主要分三类：
Spring testing machines are mainly divided into three categories:
1、弹簧拉压试验机。
1. Spring tension-compression tester.
2、弹簧扭转试验机。
2. Spring torsion tester.
3、弹簧疲劳试验机。
3. Spring fatigue testing machine.
