Nonlinear Dynamic Analysis of a Typical Fuze Supporting Plate Considering Shock Loading

On the basis of nonlinear dynamic bending model of a typica fuze supporting plate, the nonlinear problem is disposed using the perturbation perturbation method and the way of general medal analysis is opened up using the central difference metjod.The problem of response analysis for the forced vibrations is settled using the modal superposition method. As an example,the nonlinear dynamic response of the supporting plate of a missile fuze has been analysed and calculated.
