摘要

A high-precision transient energy response prediction method for a complex structure, including: taking a time dependent term (formula I) of energy transfer between subsystems into account; establishing a transient power balance equation of each subsystem of the structure by combining with a loss factor matrix η n of the complex structure; and given initial boundary parameters, adopting fourth-order and fifth-order Runge-Kutta algorithms to calculate transient energy response of each subsystem of the structure. The present invention establishes a more complete transient energy balance equation for each subsystem of the complex structure by taking the time dependent term of energy transfer between the subsystems of the complex structure into account, thereby significantly improving the prediction precision of the current transient statistical energy analysis method in the transient energy response prediction, and expanding the research scope of the current transient statistical energy analysis method.
