“…Additionally, Andro [10] used similar techniques to those of Park to obtain a nonlinear model for the static part and a good approximation was achieved of the dynamic behaviour of the elastomer's Young Modulus using an additional seal shape.…”

“…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. All these previous work depends on the particular design and material properties to provide insight into the proposed method and validation.…”

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.

Door closing sound quality of a vehicle has become one of the most important customer-related quality metrics in the recent years. There has been a vast amount of information on the design parameters contributing to this attribute in the literature. Amongst them, damping pad on the door outer panel emerges as one of the most significant factors on the door closing sound quality. In this paper, we apply solid isotropic material with penalization topology optimization method to determine the optimum material layout for within a given volume constraint on a front door of a typical vehicle. The objective function of the topology optimization is chosen as the minimization of residual sum of squares of the accelerance of the door outer panel up to 200 Hz. The optimization problem is subject to design constraint to use a predetermined percentage of the full damping pad. The methodology is demonstrated on the finite element model of front door of a Toyota vehicle. Two optimization case studies using 60% and 45% of the damping pad on the door outer panel are introduced as a result of the application of the proposed topology optimization methodology. In addition, more manufacturable optimization configurations with the same % of the damping pad are suggested as a means for more feasible application by automotive original equipment manufacturers. All the optimization configurations are compared to each other on (i) accelerance spectrum up to 200 Hz, (ii) residual sum of squares of the accelerance, and (iii) weight of the damping pad. The results show that it is possible to improve the aforementioned metrics significantly by the application of topology optimization.
