Failure analysis of a dynamometer drive shaft coupled to an engine
A typical dynamometer drive shaft was damaged during its working condition. This failure was repeated in four cases. In the present article, a failure analysis of a dynamometer drive shaft has been performed. To analyze the failure, the material investigation was carried out by scanning electron microscopy (SEM) images. Additionally, the micro-structure of the failed coupling shaft was photogra...
متن کاملDynamic analysis of three-cylinder engine with balancing shaft
Three-cylinder linear engines are designed to minimize, reduce fuel consumption and pollution. The disadvantages of this type of engine, heavy vibration inherent in them. this study aims to balance Three-cylinder linear engines with a balancing shaft. First, the dynamic analysis of these types of engines identifies unbalanced sources. The results of the dynamic analysis showed that the inertial...

متن کاملVibration Analysis of Rotating Shaft with Loose Disk
In this paper energy method is used to calculate rotor response with loose rotating disk on it. System equation of motion is obtained based on energy method and Lagrange equation. Mathematical modeling of loose disk in a rotor bearing system has resulted in terms similar to unbalance and gyroscopic effect in the system equation of motion. The effect of loose disk axial position and orthotropic ...
متن کاملModel identification and dynamic analysis of ship propulsion shaft lines
Dynamic response analysis of mechanical structures is usually performed by adopting numerical/analytical models. Finite element (FE) modeling as a numerical approach plays an important role in dynamic response analysis of complex structures. The calculated dynamic responses from FE analysis are only reliable if accurate FE models are used. There are many elements in real mechanical structures w...
