It'll allow analyzing this system dynamic state under parameters changing both of system itself and of external loading. The recommendations for special software application and own software application at the same time for such investigations and analysis fulfilling were worked out as well. The technique of simulating of elastic systems non-stationary stochastic behavior under the influence of seismic excitation was developed. The technique was built with the use of the finite element method, nonlinear elasticity theory, wavelet analysis and the theory of motion waves. The numerical approach for estimating of response (displacements, velocities, accelerations) of elastic systems on seismic loads is presented. The approach is based on the fourth-order Runge-Kutta direct method of numerical integration and methods of wavelet analysis in frequency-time space. Product Description popup.authors Баженов В.
