摘要
为防止输电线路舞动,提出新的舞动力学模型,即在弦振动方程中引入了非齐次方程边界条件和抛物线初始条件,求解和分析弦振动方程。还提出了防止悬吊系统的固有频率和导线的固有频率具有匹配关系、防止导线振动时相互共激、以及装设防振锤和阻尼线等措施。
A new dancing mechanics model is proposed to protect transmission lines from dancing ;non -homogeneous equation boundary condition and parabola beginning condition are led into chord vipration equation which is solved and analyzed. Meanwhile,protecting measures from dancing are proposed.
