摘要
本文讨论了Euler梁的离散模型在任意边界支承(固支、铰支、滑支和自由)下的固有频率和模态的定性性质。文中指出梁的非零频率是分离的,并给出了梁的单个非刚体模态满足的充要条件。
In this paper we discussed the qualitative properties of frequencies and modesfor the discrete model of an Euler Beam vibrating under different bounderyconditions (clamped, pinned, sliding and free). It was shown that non-zerofrequencies of the beam are distinct. The necessary and suffecient conditionssatisfied by a non-rigid-body mode were established.
