| Abstract: | Amending the natural frequency of vibration rod is an important means to raise the efficency of the vibration system. In this paper,the energy method is adopted. By means of analyzing the effect upon the kinetic energy of vibration system caused by cross-coupling, the amended formula for natural frequency of the longitudinal vibration rod with variable cross-section is obtained. The expressions of natural frequency for two frequently used vibration rods are given. Some calculations are carried out, comparisons made in detail. |
