1. Main functions of leaf spring fatigue testing machine :   

TPW -100/200/300/500 series electro-hydraulic servo leaf spring fatigue testing machine is a special purpose developed by our company using domestic advanced and mature electro-hydraulic servo dynamic testing technology, combined with years of industry experience in spring testing machines, Series products for spring fatigue. This testing machine is mainly used for dynamic fatigue test and static characteristic test of leaf springs, and can also be used for fatigue test of other similar parts with accessories. Meet GB/T19844-2005, JB3383

2. Main technical indicators of leaf spring fatigue testing machine :

1. Maximum static test force: ±100/200/300/500kN, indication accuracy ±1%;

2. Maximum dynamic test force: ±100/200/300/500kN, amplitude fluctuation is not more than ±2%FS;
