作为发展机械和结构边界条件识别技术的基础研究，提出了一种新的圆板边界条件识别技术。该方法具有不需要边界实测数据的特点，适用于非线性边界条件。在提出的技术中，边界由弹簧和阻尼器以及有效质量和惯性矩建模。然后利用解析解结合实验数据确定了它们的特性。由于该技术是基于解析解的，所以只要能推导出其解析解，它就适用于任何结构。数值模拟结果表明，该方法能准确地确定边界条件。
As a basic study for developing an identification technique for boundary conditions of machines and structures, a new technique for a circular plate is proposed. This technique has features that do not require data measured on the boundary and is applicable to nonlinear boundary conditions. In the proposed technique, the boundary is modelled by springs and dampers as well as effective mass and moment of inertia. Then their characteristics are determined by using the analytical solution together with the experimental data. Since the technique is based on the analytical solution, it is applicable to any structure, provided that its analytical solution can be derived. Numerical simulation is conducted to show that the procedure determines the boundary conditions accurately.
