- Abstract
- This study deals with the passive control of the dynamic characteristics of a theoretical model which is astring with fixed ends and loaded by two point masses - a main mass (Mo) and a secondary mass (Ms). It hasbeen controlled passively by means of a relocation of a secondary mass. A main mass placed on the string isconsidered as a vibrating receiver which be forced to vibrate by a vibrating source being positioned on thestring. By analyzing the motion of a string, the equation of motion for a string was derived by using a methodof variation of parameters. To define the optimal conditions for the vibration reduction, the governing equation,which denotes the dynamic response of a string was derived in the closed form and then evaluated numerically.
The possibility of reduction of an amplitude and a power being transmitted to a main mass were found todepend on the location and the magnitude of a secondary mass as well as the range of a forcing frequency.
