| Popis: |
An innovative concept has been developed in which the dynamic behaviour of a cylindrical cam mechanism is modified using inertial compensation techniques. Elastic and magnetic compensation systems are incorporated in the experimental acoustic and acceleration analysis procedure. Both compensation systems have a remarkable effect on the reduction of the noise and vibration levels produced by the impact between the cam follower and the groove inversions. However, individually they both have different influences on the groove junctions. Generally they both have a considerable effect on the integral cam mechanism in terms of reducing emitted sound levels. The results also show that the difference in emitted sound levels before and after modification is approximately 3 dB. This conclusion means that the difference of the equivalent sound level is roughly equal to a reduction of about thirty percent below the original level with the compensation devices in position. |
