Abstract
The nonlinear dynamical equations of tilted support spring system with critical components were established under the action of semi-sinusoidal pulse, and the equations were solved using Runge-Kulla method. The shock response characteristics of the critical components were obtained and analyzed. To evaluate the shock, a new concept of shock response spectra was proposed. The ratio of the maximum shock response acceleration of the critical components to the peak pulse acceleration and the dimensionless pulse duration were employed as the basic parameters of the shock response spectra. Based on the numerical results, the effects of the peak pulse acceleration, the dimensionless pulse duration, the angle of the tilted support spring and the frequency ratio of the system on the shock response were discussed. It is shown that the effects of the angle of the tilted support spring and the frequency ratio of the system are particularly noticeable. By increasing frequency ratio of the system, the maximum shock response acceleration of the critical components can be obviously decreased, while the peak of the shock response of the critical components can be decreased by increasing mass ratio at low frequency ratio.关键词
