“…Since the transfer function matrix method is expected to yield accurate predictions for the set of assumptions made in the analysis, this result demonstrates the accuracy of the numerical model. In agreement with results by Gur and Morman [9], there is a resonance frequency where R TL become zero. This frequency corresponds to the mass-air-mass resonance frequency of the seal.…”

Automotive metal door panels and nonmetallic seals have complicated nonlinear interactions in their narrow mating sections, leading to non-uniform compression and complicating the sound transmission mechanism. Therefore, a new sound transmission modeling methodology and numerical analysis is developed for a refined sealing system by considering the geometrical boundaries and the non-uniform compression load. Nonlinear analysis is performed to obtain the geometrical parameters of the deformed seal, which are later input to the subsequent numerical acoustic model, by varying the compression ratios at different door locations under quantified nonlinear metal–seal interaction boundary conditions. A numerical prediction model of the sound transmission loss is constructed considering the deformed seal geometry using a double-wall-panel sound transmission model. Finite-element analysis and an infinite-element method are combined. Sound transmission loss experiments are conducted by varying the compression ratios of the seal. Experimental results are in good agreement with the numerical analysis. Furthermore, the sound transmission loss of the incident sound source with respect to a wide range of frequencies is numerically predicted for different compression magnitudes and directions using the verified methodology. This shows that the presented model and numerical methodology is valuable for optimizing the sound transmission loss performance of automotive door seals.

“…Park et al 2,3 worked on representative sealing layers for bulb geometry and presented a transfer matrix method to calculate overall sound transmission loss (STL). Gur and Morman 4 compared their results with vehicle level measurements after finite element method (FEM) predictions to assess the performance of sealing systems. Andro et al 5 provided a brief comparison of FEM results and experimental measurements.…”

Noise isolation properties of the closure systems are important factors for the acoustic performance of vehicles. This study explains sound transmission through a door sealing system, and numerical methods analyze all acoustic responses’ parameters. A specific design of experiments (DoE) analysis is carried out to reveal the effects of each material along with the predefined geometric entities and their dimensions. Viscoelastic material parameters are included with full factorial designs for a particular geometry. Material optimization is implemented with the Taguchi method by incorporating noise factors. Optimization of the geometric entities is studied, and the best section shapes for acoustic performance are obtained. A robust optimization study is conducted by considering the uncontrollable noise factors. Consequently, the door closing efforts compromise the acoustic design to present an overall method with design constraints.
