Analysis of Nonlinear Vibration on a Diesel Engine Part 2007-24-0058

The vibration problems concerning engine parts can be explained for the almost part by using the linear vibrations analysis method. The nonlinear vibration system in which spring stiffness changes with the spring elongation causes interesting phenomena such as the resonance suddenly stopping at a certain frequency and the resonance suddenly reappearing at another frequency. This paper reports characteristic phenomena, generation mechanisms and control methods for nonlinear vibrations through discussion of the results of engine testing, rig testing and calculations.
