摘要
在考虑弹簧本身质量的条件下,采用能量法分析圆台形弹簧系统的总动能.通过引入形状函数导出有效质量系数的精确表达式.其有效质量系数的变化范围为1/5~8/15.
Considering the mass of the spring itself, an energy method is adopted to analyze the total kinetic en-ergy of the truncated cone-shaped spring system,An accurate expression of the effective mass coefficient is derived by introducing the shape function,And the range of the effective mass coeffiicient is between 1/5 and 8/15.
