摘　　要：运用迭加法计算均布载荷作用下相邻两边固定,一边简支,另一边自由矩形弹性薄板的挠曲问题,结合有限元分析软件ANSYS数值模拟的结果,验证该板型用迭加法所得结果的精确性,分别分析迭加法和数值模拟技术的优点和不足,进而说明迭加法和数值模拟技术有效结合的长处,及其对实际工程和弹性薄板的理论研究具有特别重要的意义.In this paper, superposition method is applied to the study of the deformation of elastic thin plate with two fixed adjacent sides： one freely-supported side, the other free side under uniform pressure. Numerical modeling is applied, and the result is pointed to be a criterion. In order to guarantee the accuracy of the result of superposition method, the result is compared to the criterion. The advantage of them can be found when they are applied together. In practice, if superposition method can be applied by cooperating with numerical modeling, it will be very great.
