Influence of Successive Two Moving Spring-Mass Systems on Dynamic Behavior of a Simple Beam Subjected to Uniformly Distributed Follower Forces

연속이동 스프링-질량계가 등분포종동력을 받는 단순보의 동특성에 미치는 영향

A simple beam subjected to a uniformly distributed tangential follower force and the successive two moving spring-mass systems upon it constitute this vibration system. The influences of the velocities of the moving spring-mass system, the distance between the successive two moving spring-mass systems and the uniformly distributed tangential follower force have been studied on the dynamic behavior of a simple beam by numerical method. The uniformly distributed tangential follower force is considered within its critical value of a simple beam without the successive two moving spring-mass systems, and three kinds of constant velocities and constant distance of the successive two moving spring-mass systems are also chosen. Their coupling effects on the transverse vibration of the simple beam are inspected too.
