An analytical method and a result for obtaining dynamic stresses in the valve-spring of a driven valve system of internal combustion engines are presented with a consideration of the end effects. To treat the complex dynamic behavior due to cam rotation with complex profile, this paper applies a combination method of the transfer matrix, the Laplace transform and the Fourier series expansion procedures. Numerical calculations have been carried out for a sample case of general valve-springs, and the numerical results for the dynamic stresses have been obtained in the case of a spring excited by the driven valve system.
