摘要: 给出了噪声载荷作用下薄壁柱壳结构随机振动加速度响应功率谱密度的计算公式和计算方法,并与实际测量获得的加速度响应功率谱密度进行了比较,计算的功率谱与实测的功率谱具有较好的一致性,说明这种估算噪声载荷作用下薄壁柱壳结构随机振动加速度响应功率谱密度的方法是合理可行的。用同样方法导出的Von Mises应力响应的功率谱密度及其均方值的计算公式,可直接用于疲劳强度分析。Abstract: This paper presents the estimated method for the power spectral density of vibration acceleration response of thin cylindrical shell excited by noise. The estimation is compared with the experience of a thin cylindrical shell excited by noise. They have a good agreement. Then a set of formula calculating the power spectral density of Von Mises stress response and its mean square value is given. The result can be applied to fatigue analysis.
