摘要
应用变积方法建立了弹性动力学Gurtin型拟变分原理。应用弹性动力学Gurtin型拟变分原理对电机轴系的扭转振动问题进行了分析,并求得电机轴系的固有频率。
Gurtin-type quasi-variational principle of elasto-dynamics is established by variational integral method in this paper. The problem of torsional vibration of electric engine axial is analyze by Gttrtin-type qusi-variational principle. And natural frequency of electric engine axial system is obtained.
