Description
The engine mounting plays an important role in reducing the noise, vibrations and harshness for improving vehicle ride comfort. The first and the foremost function of an engine mounting bracket is to properly balance the engine on aero plane wing for good motion control as well as good isolation.
This project deals structural and fatigue analysis of engine bracket operating at three different temperatures with applied loads. Normal operating loads are applied and thermal loads are kept at room temperatures,
-40°C and +52°C conditions. Fatigue life is evaluated at critical locations. Goodman criteria is used for means stress correction and S-N curve is use to evaluate the number of cycles. Cumulative fatigue damage is carried out using Miner’s rule. Critical locations are evaluated for fatigue life and damage estimation.
The results are evaluated and verification is done for strength and durability of the engine bracket operation at different temperature environments. Fasteners selection verification is carried out in the current analysis.
