Abstract

typical rotating machinery system consists various components, such as rotor, support bearing, and disks. These components

pass out energy into the system when coincident to critical speeds. Ignoring such event might lead to disastrous breakdown of the

system. Due to necessity and vital contribution to most rotating machineries, the requirements on rolling element bearings have

become stricter every day. In this experimental study, the dynamic behavior and displacement of rotor supported by damped rolling

element bearing housing for different running speeds and load levels are analyzed and compared.

Keywords
