摘　　要：采用静力问题的格林函数作为权函数,建立薄板动力问题的边界积分方程式,并将惯性力项作为面分布载荷处理.实例计算表明,本算法具有较高精度,与理论解吻合甚好.We introduce a method to establish the bounnary integration equa-tions for dynamic problems of thin plates by employing the Green's function ofstatic problems,in which the inertia term is regarded as distributing loads.Numerical results show that the method is of high accuracy and consists withtheoretical solution
