Computer aided analysis of balancing of multi cylinder radial and v- engines

Abstract

The reciprocating engines are the prime source of power generation in various mechanical applications ranging from power generation to automobiles. Noise, vibrations and harshness are caused in this engine due to unbalanced inertia forces and moments which further cause complications in their operation. To minimise the unbalance, analysis for the unbalanced forces and moments for different configuration of cylinders and firing order of multi-cylinder radial and V engines are done. The C programs have been developed for this analysis to minimise the time and calculations. The radial, V engines and combined radial and inline configured engines are compared on the basis of resultant unbalanced forces and moments.
