【摘要】 给出一个动载荷识别的时域方法。该法将控制论中的逆系统理论用于载荷识别，将载荷识别这种逆问题转变成正问题来处理，得到离散系统和连续系统载荷识别的计算模式。文中方法可以识别载荷的时间历程、载荷的作用位置、载荷的分布规律。通过仿真和实验，验证了方法的有效性。更多还原

【Abstract】 This paperproposeda time domain method todetermine force.The method thispaperproposed applied inverse system theory in thedeterminatoon of force. Changing theldentification of force which is an inverse problem into a normal problem,we obtains formulasto identify the forces of discrete and continuous systems. The proposed method can be used todetermine the time history of force, the location offorce and the dlstribution of distributiveloads.Plenty ofcalculating examples and experiments have beendone andthe results indicatethat the method is effective.更多还原
