Question

A 200 kg engine operates at 1200rpm. Design an isolator such that the transmissibility ratio during start-up is less than 4.6 and the system achieves 80% isolation during normal operation.

Answer 1

To design an isolator for an engine, consider the natural frequency, stiffness, and damping properties.

Step-by-step explanation:

An isolator is a device used to reduce the transmission of vibrations from one component to another. In this case, we need to design an isolator for an engine that operates at 1200rpm and has a mass of 200 kg. The transmissibility ratio is a measure of how much the vibrations are reduced by the isolator, and we want it to be less than 4.6 during start-up.

During normal operation, we want the isolator to achieve 80% isolation. To design the isolator, we need to consider the natural frequency of the engine and the isolator's stiffness and damping properties.
