Abstract

This paper describes the common structure of the longitudinal composite leaf spring as well as the stress of different parts. Combined with force analysis, various failure modes may occur in the middle and end parts of the composite leaf spring. Attention should be paid to the stress concentration in the clamping area in the middle of the leaf spring, caused by U-bolt pre-tightening. At the end of the composite leaf spring, enough bolt hole-edge distances shall be ensured and attention should also be paid to the stress concentration caused by the bolt. In spring design, the static stiffness of the composite leaf spring can be appropriately increased to ensure the suspension has sufficient offset frequency. At the same time, attention should be paid to the glass transition temperature (Tg point) value of the resin, which is suggested to be higher than 80 °C.
