摘要: 在弹簧质量不能忽略的情况下,推导了n个弹簧串联系统的动能和弹性势能具体表达式,结果表明:n个串联弹簧系统的动能与每个弹簧自身质量、劲度系数密切相关;系统的弹性势能由”个串联弹簧的等效劲度系数和串联弹簧的总伸长量决定.

关键词: 能量, 串联弹簧, 弹簧振子, 劲度系数

Abstract: The total kinetic energy and elastic potential energy of springs in series are discussed in the case that the mass of spring can not be neglected. It turns out that kinetic energy of springs in series is related with every spring mass and coefficient of stiffness. However, elastic potential energy is only decided by absolute elongation of springs in series and their coefficient of stiffness.

Key words: energy, springs in series, spring oscillator, coefficient of stiffness
