In order to improve the accuracy of load identification and study the influence of transverse distribution, a novel method was proposed for the moving load identification based on strain influence line and the load transverse distribution under consideration. The load identification theory based on strain influence line was derived, and the strain integral coefficient was proposed for the identification. A series of numerical simulations and experiments were carried out to verify the method. The numerical results showed that the method without considering the load transverse distribution was not suitable for solving the space problem, and the method with the load transverse distribution under consideration has a high identification accuracy and excellent anti-noise performance. The experimental results showed that the speed identification error was smaller than ±5%, and the vehicle speed had no obvious influence on the identification results of the vehicle weight. Moreover, the average identification error of the vehicle weight was smaller than ±10%, and the error of more than 90% of samples was smaller than ±5%.

基于应变影响线的运动载荷识别方法研究

为了提高载荷识别的精度并研究横向分布的影响，提出了一种基于应变影响线和考虑载荷横向分布的运动载荷识别新方法。推导了基于应变影响线的载荷识别理论，并提出了应变积分系数进行识别。进行了一系列数值模拟和实验以验证该方法。数值结果表明，不考虑载荷横向分布的方法不适合解决空间问题，考虑载荷横向分布的方法具有较高的识别精度和优异的抗噪性能。实验结果表明，车速识别误差小于±5％，车速对车重识别结果无明显影响。此外，车辆重量的平均识别误差小于±10％，超过90％的样品的误差小于±5％。
