To understand the mechanism of inter-leaf friction in leaf springs, the author tried the vibration test for three kinds of springs.
By these tests it has become clear that damping factors and natural frequencies are variable with amplitude. It is considered that variation of damping factor shows complex of friction mechanisms, and variation of natural frequency is due to hysteresis characteristics.
Now, the author intends to investigate variation of forced vibration characteristics by amplitude and relation of vibration test to static test and, moreover, influence of nip, lubrication and liner between leaves on vibration characteristics of leaf spring.
