Design and Modal Analysis of Balance Shaft at Inclined Position for a Single Cylinder Engine
Noise and Vibration of single cylinder diesel engine cause a great impact on the performance and other function of the engine. Engine’s vibration is determined by total unbalance inertia force. Most of the time balancing of total unbalance inertial forces of the single cylinder engine requires re-engineering of the engine that increases weight and cost. This paper describes the balancing of unbalance inertia forces with minimum modification in engine i.e. Using balance shaft mechanism. Balance shaft mechanism cancels the unbalance inertial force as balance shaft assembled to crank shaft. In this paper, size, shape, and position of the balance shaft in a single cylinder engine are identified by simulation. The total unbalanced inertial force with and without balance shaft in the engine are obtained by rigid body dynamic analysis in ANSYS. The balance shaft designed is verified for resonance using FFT analyser.
