轴对称加载的阶梯式压力容器的径向振动

Radial Vibrations of Axisymmetrically Loaded Stepped Pressure Vessels

用奇异函数建立轴对称加载的阶梯式压力容器径向自由振动和强迫振动的微分方程并求得其通解。

Differential equations of free/forced radial vibrations of axisymmetrically loaded stapped pressure vessels are established by using singular functions. Furthermore,their general solutions are solved , the expression of vibration mode function and frequency equations on usual supports are derived with W operator and forced response of such vessels are calculated.
