The Numerical Solution of the Dynamic Response of Helical Springs.
Abstract
An analysis was conducted during the period of November 1975 to May 1976 to determine the dynamic response of helical springs under axial impact with particular application to the return spring in the M60A2 tank recoil mechanism. The study was performed by the University of Illinois at Urbana, Illinois under the direction of the General Thomas J. Rodman Laboratory, Rock Island Arsenal. The dynamic behavior of the impacted spring is described by two coupled nonlinear partial differential equations. Two computer solutions to the equations are obtained by the methods of finite differences and nonlinear characteristics. Results of the two numerical techniques are compared with the closed form solution of the linear equations. The study indicates that frictional binding may occur between the spring coil diameter and the guide components which will result in failure to return to battery. (Author)
