由正交异性板的响应识别移动荷载

Moving Loads Identification through Responses of Orthotropic Plate

建立移动荷载引起的正交异性板动力响应的计算公式，当移动荷载为常荷载时，板的响应可精确解得。在此分析基础上导出板上多个移动荷载与板的多点响应或单点多时刻响应的关系，由最小的二乘法识别移动荷载。通过算例讨论了响应的测试误差对识别结果的影响。

The equation for calculating the vibration response of an orthotropic plate caused by moving loads is established. The response can be precisely solved if the loads are constants. Based on the response analysis, the relations between the loads and the multi gage stations response or one gage station response at multi times are establishel, and the moving loads on the plate are identified by the least square method. A simulation example is introduced to discuss the effect of test error on the loads identification.
