摘要
对一种动态载荷识别的计权加速度方法进行了数值仿真研究。设计了一悬臂梁的有限元分析与数值模拟算例 ,结果表明 ,对只作用在一个节点上的三角脉冲载荷而言 ,此方法都具有较高的识别精度。无论是离散或是连续系统 ,在模态缺省的情况下 ,结果还较令人满意的。
Carry through the numerical simulated study on the sum of weighted acceleration in dynamic loads identification.Design an example of an appending girder using limited element analysis and numerical simulation.The result indicates that distingusihed precision of this kind of method is perfect on triangle impulse load which is loaded on one node.No matter it is discrete or continuous system,the result is also satisfying if mode is defaulted
