摘要
本文讨论了机械振动部分的两个问题:(1)弹簧质量不能忽略时如何计算振动系统的回频率;(2)竖直悬挂的振子,悬挂点振动时对振子振动的影响。
Presented in the paper are two problems involved in the mechanical vibration:(1)How to calculate the cgcle frequency of the vibration system in ease the mass of the spring is nat ignored;and(2)The effect of the vibration of the hang—point on the vibrator in case of verficallg hanged vibrator.
