1. Main functions:

1. TPW -300 type electro-hydraulic servo leaf spring fatigue test is mainly used to test the dynamic and static mechanical properties of various steel pole springs. It can not only complete the leaf spring fatigue test required by the standard, but also perform the characteristic test before the fatigue test. Such as automatic drawing of test force_deformation curve, calculation of leaf spring stiffness, etc. By replacing accessories, you can also test the dynamic and static mechanical properties of other parts by hand, which has the characteristics of good professionalism, high reliability, advanced technology, and easy-to-hand upgrade.

2. Meet GB/T19844-2005 "Leaf Spring", JB3383-1998 "Automobile Leaf Spring Bench Test Method" and QCn 29035-1991 "Automobile Leaf Spring Technical Conditions" JBT 7283-2001 "Agricultural Machinery Leaf Spring" ISO18137-2015 "Leaf Spring-Technical Specifications" and other national industry standards.

3. It can complete the static and dynamic mechanical performance test of the leaf spring

1) Deformation test under vertical load

2) Leaf spring characteristic test: automatically draw test force-deformation and calculate leaf spring stiffness.

3) Dynamic mechanical performance test of leaf spring.
