What is a leaf spring:
Leaf Spring is the most widely used elastic element in automobile suspension. It is an elastic beam of approximately equal strength composed of several alloy Spring plates of equal width but unequal length (thickness can be equal or not equal).
Executive standard:
JB3383 Test Method for Automobile Leaf Spring Bench
JB523 Technical Requirements for Automobile Leaf Springs
QC T 29035-91 Tests as required in technical Conditions for Automobile Leaf Springs standard.
Leaf spring dynamic and static fatigue testing machine
Electro-hydraulic servo spring testing machine, our company adopts the domestic leading mature electro-hydraulic servo dynamic test technology, combined with many years of experience in the spring testing machine industry, and developed for the static performance of leaf spring and dynamic fatigue series of products.
The testing machine has the dual functions of static and dynamic tests, and integrates the traditional static and dynamic tests on a testing machine, which has important economic and technical value.
