In this my 😀  undergraduate project 😀, I investigated the behavior of an engine mount using both experimental and numerical methods. 

The analyses included two parts:

1. Static analysis
2. Harmonic analysis under frequency-based loads.

The main objective of this study was to design a new engine mount capable of better damping vehicle accelerations and impacts.

This project was carried out using the Abaqus software for numerical simulation, and the results were compared with experimental data. I gained valuable insights from this work, which I am happy to share. Feel free to ask any questions regarding the study.

Simulation Methodology:

• Static Modeling:

For static analysis, the hyperelastic properties of the engine mount were considered. The most commonly used model in this context is the Mooney-Rivlin model, which is categorized based on material hardness using the Shore hardness parameter. In this project, the engine mount material was modeled with a Shore hardness of 55.

The loading was applied in four different directions, as shown earlier.

• Harmonic Modeling of the Engine Mount:

1. First, the engine's weight was applied to the mounts, and a static analysis was performed.
2. A frequency analysis was then conducted to examine the engine mount's response.
3. Finally, a harmonic analysis was performed within a specific frequency range to evaluate the engine mount's behavior under harmonic loads.

Experimental and Simulation Results:

• Experiments were conducted in four different directions to evaluate the stiffness of the engine mount.
• Displacement values in these four directions were recorded and compared with the simulation results.

• The results demonstrated that the engine mount effectively damped vibrations and accelerations under harmonic loads.
