Research on Air-Structure Coupling Characteristics of Sounding Board Shanbao Pei1,2,a, Rongzhong Liu 1,b 1School of Mechanical Engineering, Nanjing University of science and Technology, Nanjing, Jiangsu, 210094, China 2School of Mechanical Engineering, Anhui University of Technology, Ma’anshan, Anhui, 243002, China ashanbaopei@163.com, bliurongz@mail.njust.edu.cn Keywords: Sounding Board, Virtual Mass Method, Air-Structure Coupling, Modal Abstract.
The Motion Equation of Sounding Board To solve the motion equation of the sounding board, the damping role of the blade can not be taken into account because the structural damping of sounding board has been included in the material constitutive equation.
The spring length is 50mm, the material of sounding board blade is steel, and the elastic modulus is 2.05×1011N/m3, poisson ratio is 0.3, density is 7.85×103kg/m3.
