【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固有频率的影响,重点研究了直径对固有频率的影响.结果表明,横向振动使得振动系统中纵振动的固有频率降低.理论和实验结果都表明,同样长度的杆,截面增大时纵振动的固有频率降低.更多还原

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