Abstract EN
The instrument panel assembly is an important structure to shield powertrain noise and front wheel noise, and the instrument panel sound insulation system plays a key role in it.
Therefore, the sound insulation characteristics of the instrument panel sound insulation components appear particularly important.
In the existing technology, the acoustic design of instrument panel mostly adopts the reverse design method and pays little attention to the forward design of acoustic system, which tends to lead to the shortcomings such as inaccurate acoustic design and poor acoustic design quality.
The reverse design also restricts the development cycle, so the control and design of acoustic performance cannot be realized in the initial stage of design.
Based on the above problems, the statistical energy model of the dashboard model was established by combining the statistical energy flow method and the proxy model method, and the influences of different acoustic cladding layers, different thickness, leakage, and new material microfibers on the sound insulation parameters of the front coaming were simulated.
The general rules that affect the sound insulation performance of the structure are obtained.
On this basis, multiobjective genetic algorithm and proxy model method are used to optimize the insertion loss of the front panel acoustic pack and the weight of the dashboard by introducing multiobjective variable and experimental design method, so as to obtain the best solution to meet the requirements of insertion loss and lightweight acoustic pack of the dashboard.
It is of great engineering significance for the development of acoustic components for forward design instrument panel.
