TPJ系列弹簧疲劳试验机是由驱动系统、传动系统、控制显示等系统组成，适用于各种螺旋弹簧的疲劳性能试验。该试验机由电磁调速系统控制电机运行，通过偏心装置带动连杆使往复压板上升、下降，完成对弹簧的往复压缩疲劳试验。该机无污染、效率高，具有较宽的调频范围和试验空间，配上合适的辅具，可完成不同规格的弹簧疲劳试验。
TPJ series spring fatigue testing machine is composed of driving system, transmission system, control display system, etc. it is suitable for fatigue performance test of various spiral springs. The testing machine is controlled by the electromagnetic speed control system. The eccentric device drives the connecting rod to raise and lower the reciprocating pressing plate, thus completing the reciprocating compression fatigue test of the spring. The machine is pollution-free, high efficiency, has a wide range of frequency modulation and test space, with suitable accessories, it can complete different specifications of spring fatigue test.
