支撑点与振源重合的圆形薄板二维驻波的实验与仿真研究

Research on experiment and simulation for two dimensional standing waves on circular plate whose support coincided with vibration source

通过实验和MATLAB软件对支撑点与振源在圆心重合的圆形薄钢板上的二维驻波进行了测量、数值计算和仿真研究,测量结果和数值计算以及仿真均与理论计算吻合,并给出一种测量材料杨氏模量的简单方法.在大学物理层面,对于物理实验和仿真做了有意义的尝试.

In this paper,the two dimensional standing waves on circular plate whose support coincided with vibration source are measured,calculated and simulated by experiment and MATLAB. The testing results follow with MATLAB’s simulation very well. It has shown a method to measure the Young modulus. It is a significant practice for college physics experiment and simulation.
