Effect of Eccentric Imbalance of Various Crank Train Components on Vibrations in Single Cylinder Diesel Engines 2019-28-2417

Diesel engine is the main source of power for many agricultural applications such as water pump sets, compressors and tractors. At the same time it is also the main source of vibrations. Mechanical vibrations have instantaneous and long term effects on human body. Kinds of effects depend upon duration of exposure and frequency of vibrations. The increasing demands of improved comfort levels of operators are putting pressures on tractor manufacturers on reducing the vibration levels which thereby resulting in improving diesel engine vibrations.
Vibration is the movement or mechanical oscillations about an equilibrium position of a machine or component. A Vibration analysis is about the art of looking for changes in the vibration pattern and then relating those changes. Vibration always occurs when there is unbalanced body in reciprocating or rotary motion. In an internal combustion engine there are many parts in reciprocating and rotary motion such as pistons, connecting rod, crankshaft, flywheel etc.
This paper explains the study carried out to evaluate combined effect of location of unbalance in individual components when they are assembled and work as a system.
This study was carried out to assess the impact of change in of vibration pattern from Lateral to Vertical, Change of location of an eccentric mass, changes in acceleration/displacement pattern with different percentage of balancing
