本文提出了一种新的正则化方法，并将其应用于复合材料层合圆柱壳表面多源动载荷的识别。一般来说，正则化是一个不适定问题被一个邻近适定问题族的近似。通过构造一种新的正则化算子，建立了相应的正则化方法。提出了一种正则化算子，从而构造了一种新的正则化方法，并证明了其正则性。将该方法应用于复合材料层合圆柱壳的载荷识别。瞬态位移响应可以通过有限元方法得到。通过对复合材料层合圆柱壳表面多源动载荷的识别，验证了该方法的有效性和鲁棒性。
In this article, a new regularization method is proposed and applied to the identification of multi-source dynamic loads acting on a surface of composite laminated cylindrical shell. In general terms, regularization is the approximation of an ill-posed problem by a family of neighbouring well-posed problems. Based on the construction of a new regularization operator, corresponding regularization method is established. We propose a regularization operator, thus construct a new regularization method, and prove its regular property. The present method is applied to load identification of composite laminated cylindrical shell. The transient displacement response can be obtained by the finite element method. The multi-source dynamic loads on a surface of composite laminated cylindrical shell are successfully identified, which demonstrates the efficiency and robustness of the present method.
