“…The ever-growing number of electrified automobiles has encountered a significant challenge in reducing the noise, vibration, and harshness (NVH) of vehicles [1,2]. Particularly, the unwanted gap and flush in the moving parts (e.g., hood, doors, and so on) can lead to poor appearance quality and NVH issues, such as cavity and whistling noises [3][4][5][6].…”

Automotive hood, a closure system of the engine compartment, needs to be mounted in a suitable position to avoid irregular gaps and flush when it is initially assembled. Hood panel is mounted with an elastomer part called weatherstrip that is generally made of EPDM foam material for sealing and reducing vehicle vibration and whistling noise. Since the elastomer material exhibits non-linear mechanical properties and viscoelasticity, which result in unpredictable reaction force and compression set, finite element analysis (FEA) of the automotive hood panel displacement with weatherstrip model shows low precision and long computing time. To resolve this issue, in this study, a cost-effective methodology for FEA is introduced by applying compressive stress of weatherstrip into distributed surface load in the finite element model without weatherstrip modeling. In addition, 2D FEA of the weatherstrip was performed to investigate the effect of structural parameters on the reaction force. This work demonstrates a numerical approach for predicting automotive hood displacement, considering not only the material properties but also the structural design variables of the weatherstrip. Therefore, this approach can be applied to other closer parts where it requires highly efficient yet reliable predictive results for mounting position.

When talking about the car door and its importance, all aspects should be considered. Main applications of the door is the protection of passengers from outside weather variations such as air flow, temperatures, dust, side impact, etc. As a part of the car, it is connected to the car body by means of hinges, latch, and weather seals. It is excited by all excitation sources which excite to the vehicle plus vehicle accessories. Car door design evaluation is nothing but simulation of real application of door with different loading and boundary connections. An extensive literature survey and study of technical papers have been done to understand the amount of work done on Car door design evaluation during 2002 - 2022. A mainly top-level study was done to find the number of analysis papers published, the number of papers published per year, and the number of papers published of each type of analysis, and a detailed study was carried out of the papers published on NVH analysis. NVH analysis of a Car door itself is a broad area for study and research. To make it simple and streamline NVH analysis papers are sub-divided into further classes that are modal analysis, vibration and noise analysis, correlation of modal, vibration, noise, and other NVH analysis results. A thorough review of published papers provided an inside picture of the subject, the current status of Car door NVH, and the scope of future research on Car door.
