The invention relates to an automobile steel plate spring stiffness checking method which belongs to the field of automotive suspensions. Steel plate spring stiffness directly influences the performance of a suspension, but an accurate stiffness checking method does not exist. According to a mechanical model of an automobile steel plate spring, a steel plate spring stiffness checking method is established by virtue of an energy principle and a superposition principle. The established steel plate spring stiffness checking method adopts an analytical calculation method which can be used for accurately checking the steel plate spring stiffness compared with the conventional common curvature method, so that the development efficiency is improved, lots of experimental costs are saved, and the method points a direction for the design of the steel plate spring. The method can be used for design of the automobile suspension steel plate spring.
