利用Mathematica改进悬丝耦合弯曲共振法测量弹性模量实验

Improving elasticity modulus of metal materials by suspension wire coupled bending resonance using Mathematica

对悬丝耦合弯曲共振法测量金属材料弹性模量实验原理中的基本概念进行了详细描述;运用Mathematica对微分方程进行求解,得出节点位置的数值计算解,拟合出新的固有角频率公式,使实验的理论部分更加完整.提供了可深入理解该实验原理和运用Mathematica解决问题的方法和途径.

The basic concept of the experimental principle for measuring elasticity modulus of metal materials by the suspension wire coupled bending resonance method was described in detail.Mathematica software was used to solve the differential equation.The numerical solution of node position was obtained,and a new angular frequency formula was fitted,which made the theoretical part of the experiment more complete.At the same time,it provided a method to deeply understand the experimental principle and apply Mathematica to solve the problem.
