摘要
讨论了弹簧质量对谐振动固有频率的影响,作出了系统固有频率随弹簧质量的变化曲线,以及系统固有频率随弹簧几何参数变化的曲线和系统固有频率相以误差随弹簧质量的变化曲线.
Probeed the effect of the mass of a spring on the natural frequency of harmonic oscillation, and drawed the change curves of systematic natural frequency respectively with spring mass and geometry parameter, as well as the change curves of the relative errors in systematic natural frequency with spring mass.
