摘　　要：将惯性力作为作用于构件上的体积力，在处理方法上将惯性力作为作用于构件上的分布载荷求得节点载荷，推导出了弹性梁单元惯性激励力的精确表达式。The accurate expression of inertial force of elastic linkages element has been deduced.Compared with the inertial force expression that treats inertial force as concentrated load,the precisive when KED analyzing linkages element of the same degree is free.

关 键 词：梁单元 激励力 KED分析 惯性力 弹性梁单元
