摘要: 对一端固定钢条弯曲振动的共振进行了分析,指出它有一系列的振动模式,满足一定条件的策动力若频率接近其某一振动模式的频率时,则可以激发钢条共振.

关键词: 振动模式, 策动力, 共振

Abstract: An analysis of the resonance of flexural vibration of a ong-end-fixed steel ruler is made, which shows that there are a lot of discrete modes for its flexural vibration and when the frequency of some stirring force acting thereon is close to that of a mode,this mode will be excited at resonance.

Key words: vibration modes, stirring force, resonance
