Dyamic analysis of balancing of an automobile engine using ADAMS

Abstract—This paper explain the primary balancing of single cylinder engine and optimizing the counter balancing mass to reduce the unbalanced forces coming on the crankshaft. After optimizing, the effect of primary balancing is validated. After primary balancing, the vibration is measured on the engine at various locations. Balancer shaft is designed for the unbalanced forces exist after primary balancing. Balancer shaft is introduced into the simulation model and simulated the running at 6000rpm and unbalanced forces on the crankshaft are measured. The vibration on engine assembly at previously measured location is measured. The effectiveness of primary balancing and balancer shaft is validated by comparing the acceleration (m/s 2 ) measured at various locations.
