Beating in Three-Mass Systems Under Step Velocity Input. Part 1—Analytical

Abstract

The response of three-mass systems to step changes of the base velocity is discussed. It is shown that beating, which may occur between the vibrations in two normal modes, can result in a large increase in the maximum acceleration, or effective static force, undergone by one of the masses. Included are curves which show the maximum effective static forces on the system masses, and the beat frequency, for a wide range of system parameters.
