摘要
对可展开为幂级数的变截面弹性直杆的纵向自由振动问题,提出了归一化幂级 数解法,具体计算了楔形直杆、锥形直杆的自振频率,并分析了楔形比、锥形比对自 振频率的影响。
Longitudinal free vibration of the elastic straight rod with varying cross-section function, which can be expressed in the form of power series, is investigated by means of the normalized power series method. Natural frequencies of the tapered rods, whose crosssection is rectangular or circular shape respectively are calculated, and the effect of tapered ratio on the natural frequencies of the rod is discussed.
