Summary:

The internal combustion engine air intake manifold is subjected to continuous dynamic excitation due to unbalanced firing sequence and alternated movement of the pistons. An elastic anchoring for the intake manifold of Iveco's new bus was developed based on two criteria: 1. increase the natural frequency of the system to avoid coupling with engine's NEF 6 idle input and 2. minimize the vibration transmitted to the chassis. In order to solve this duality an optimization algorithm was used to fit cushion stiffness to both requirements.The system behavior is evaluated virtually in frequency domain through FRFs and its modal mode shapes and natural frequencies (eigenvectors and eigenvalues) extracted with Lanczos method
