Method for calculating friction coefficients of few steel plate springs based on frictional works

The invention discloses a method for calculating friction coefficients of few steel plate springs based on frictional works. A mechanical calculation model of the steel plate spring is established through a frictional work analysis method, and a calculation formula of the frictional works done among the steel plate springs under the working conditions of smaller loading amplitude and frequency; according to an energy conversion relation, a calculation formula of the frictional works under static load compression is derived. According to the principle that the frictional works are equal, the static friction coefficients of the plate springs are obtained. By analyzing the deforming static load of the few steel plate springs, the relative deforming speeds of the few steel plate springs are derived. By establishing a friction coefficient calculation model of the few steel plate springs, the method for calculating the friction coefficients of few steel plate springs based on the frictional works is obtained.
