【摘要】 以组合梁的模态为研究目标,通过刚度和质量等效的方法,建立组合梁的等效模型。运用有限单元法,结合实例对组合梁的自振特性进行分析,并将实际模型与等效模型的计算值进行对比。结果表明,两者吻合较好,可以为组合梁的相关设计提供参考。更多还原

【Abstract】 Taking the modal of composite beams for the research objective,by the method of that stiffness and quality are equivalent to the actual component,establish the equivalent model of composite beams.Using the finite element method,analyze the natural vibration characteristics of composite beams with examples,and compare the calculated values of the actual model with that of the equivalent model.The results show that the calculation results of the both models are in good agreement,and it may provide reference for the related composite beams design.更多还原
