【摘要】 通过理论分析和实验测量,研究了横向振动对两端自由的金属杆中纵波传播速度的影响,重点研究了直径对声速的影响.结果表明,横向振动使得振动系统中纵向振动的传播速度减小;同样长度的杆,截面增大时声速减小.这为变幅杆的设计提供了一定依据.更多还原

【Abstract】 The effect of transverse vibration on longitudinal velocity of metallic rods in a state of freedom is analyzed theoretically and experimentally, especially the effect of diameter on longitudinal velocity is studied.The results show that the longitudinal velocity reduces with transverse vibration and also reduces with the dimension of the section increasing, while the length of the rod is the same. The results may be useful to the transformer design.更多还原
