【摘要】 本文基于Ｌａｇｒａｎｇｅ方法推导了伸展悬臂梁的动力学方程，分析了伸展速度、加速度对梁动态特性的影响。对悬臂梁在不同的伸展规律、不同的外激励下的响应进行了数值模拟。结果表明，伸展长度、速度对梁的动态特性有显著影响。更多还原

【Abstract】 Dynamic equations governing the deploying cantilever beam are derived based on Largrange equations Dynamic responses of cantilever beam under various deploying laws and external forces are calculated to analysis the effects of deploying speed and acceleration on the dynamic property of the beam The result shows that the deploying laws have significant effects on the beam behaviour更多还原
