AI Technical Summary

Technical Problem

In the prior art, the moment of inertia of auxiliary equipment is much smaller than that of the engine, which makes it impossible to effectively use auxiliary equipment to suppress engine vibration.

Method used

Design an auxiliary equipment mounting structure in which the first fastening part of the auxiliary equipment is fastened to the outer wall of the engine through an elastic component, and the second fastening part is fastened directly to the outer wall of the engine without an elastic component. Furthermore, the fastening position of the second fastening part is closer to the center of gravity of the auxiliary equipment, and the flange lengths are unequal to increase the moment of inertia.

Benefits of technology

By increasing the moment of inertia of auxiliary equipment, it can effectively suppress engine vibration, play the role of dynamic damper, and reduce the discomfort of engine vibration to passengers.
