Machine vibration on a flexible roof

Holka T., Jarzyna T.

Journal of Polish CIMAC

2012

Vol. 7, no 3

69-74

The paper presents the synthesis of the receptance by using the block diagrams. The presented method is also very useful when the machine or a group of machines is mounted on a flexible roof which is hard to describe analytically. Such a case occurred while analyzing vibrations of a group of pumps installed on a floor of an assembly hall. Pumps, apart from excitations generated by the operation, are subjected to kinematic excitations from a vibrating foundation. A synthesis of the pump connection with a flexible base has been presented in this paper.
