【Abstract】 A dynamic load identification method is proposed for proportional damping systems based on high precision direct integration scheme. Firstly, modal transformation is carried out to decouple the equations of motion. Then, an equation of load identification is constructed using the proposed high precision direct scheme. Finally, the time history of dynamic loads is determined by solution of the structural dynamic response. Numerical examples are provided to validate the present method.更多还原
