This brief note examines the lumped dynamic modeling of two simple structural systems: 3D-printed cantilevers, and circular aluminum panels. In each case a set of stiffness and natural frequency measurements are made based on simple experiments, with a view to examining effective mass, and a comparison is made with the basic theory.

关于集总参数建模的说明

本简短说明研究了两个简单结构系统的集总动态建模：3D 打印悬臂和圆形铝板。在每种情况下，都会基于简单的实验进行一组刚度和固有频率测量，以检查有效质量，并与基本理论进行比较。
