中文摘要: 本文分析了连续梁横向振动主模态的解,采用按固有频率变化的集中力代替连续梁的中间支承,且在集中力作用处的变形满足原约束的要求,则该单跨梁作受迫振动时的频率,振型即为主模态.
Abstract:This paper discusses mainly the solution of fundamental mode of cross vibration of continuous beam. The middle support of a continuous beam can be relived by a concentrated force changing according to a natural frequency. The displacement of the acting point of the concentrated force should meet the requirement of the original constraint. The frequency and mode of vibration of a one-span beam during forced vibration are just the fundamental modes.
