| Abstract: | In order to improve the firing accuracy and decrease energy cost of electromagnetic launcher's rail,considering the effect of the viscous damping and the material damping,the electromagnetic launcher's rail was modeled as a simply supported beam on elastic foundation by moving load,and the mechanical model of beam was established on the basis of Euler beam theory.By using Laplace transform and Fourier transform method,the analytical solution to the equation subjected to exponential pressure was derived.The ... |
