Product Introduction:
Comply with ISO18137 Leaf Springs-Technical specifications.
Spring types: multi-leaf spring with eyes, parabolic spring with eyes, multi-leaf spring with one eye and one sliding end, parabolic spring with one eye and one sliding end, multi-leaf spring with sliding ends, parabolic spring with sliding ends, two-stage progressive multi-leaf spring with helper spring, two-stage progressive parabolic spring with helper spring, two-stage rate parabolic spring with auxiliary spring, progressive (rate) spring
Used for measuring force and deflection in rate test of leaf spring.
It can apply cyclic testing load at centre part to make leaf spring incur reciprocating deflection, used for measuring cyclic force and deflection. In general, the test frequency should be less than 3Hz, and test should not be interrupted until failure.
keywords: spring rate, design camber, fatigue test.
