摘要
应用加补充项的Fourier-Bessel双重级数的位移模式,对扇形板的自由振动问题,提出了一种应用范围比较广的、便于计算的、解析形式的解法,给出了算例,从而进一步推广了加补充项的富里叶级数法的应用范围.
In this paper, a solution in the form of Fourer-Bessel double series with supplementary terms is proposed to analyse free vibration of a sector plate. This solution is suitable to a wider range, convenience for calculation and it is in an analytical form. The results of a computional example are obtained. Thus the applied range of the Fourier series method with supplementary terms is extended.
