现举例说明量纲分析法的要点及其应用。例如分析弹性体的共振频率ψ0,应用量纲法确定相似指标的步骤如下: (1)确定影响ψ0的参数 弹性体的共振频率是弹性体尺寸L、密度ρ、弹性模量E、泊松比υ和阻尼比ξ等的函数即: ψ0=f(L,ρ,E,μ,ξ) (2)列出各参数的量纲矩阵 列量纲矩阵时 The following is an example of dimension analysis method and its application. For example, the resonant frequency ψ0 of the elastomer is analyzed. The following steps are used to determine the similarity index by using the dimensional method: (1) Determining the parameters affecting ψ0 The resonance frequency of the elastomer is the elastic body size L, density ρ, elastic modulus E, Poisson’s ratio υ and the damping ratio ξ and other functions that is: ψ0 = f (L, ρ, E, μ, ξ) (2) lists the parameters of the dimension matrix matrix dimension matrix
