Abstract null null The slamming acoustic of a vehicle door is objectively not associated to the inherent character of the automobile however it is associated to the inherent structure of the vehicle door, which is an vital subjective performance to evaluate the vehicle. Vehicle exterior noise is the air borne noise created by this structural vibration in the slamming event. This paper investigates the effect of discretized transfer paths on the abnormal vibration and adapts a modified door struc...

Abstract null null Transfer path analysis (TPA) method has been widely used in the frequency-domain applications. However, it is not suitable for transient vibration problems such as the abnormal vibration in the automotive door slamming event. In this paper, two time-domain TPA models are used for the abnormal transient vibration diagnosis in the automotive door slamming event whenever the door glass is located at its lowest location. To obtain the excitation forces, lab experiments have been c...

Many unavoidable uncertainties in the engineering structure will affect its performance response. It is necessary to analyze the uncertain responses generated by uncertain factors in the vehicle design. Therefore, this study proposes a feasible identification method of uncertainty responses for vehicle structures. The proposed method consists of radial basis function neural network (RBFNN) and Taylor interval expansion (IE) model. The optimal network parameters of RBFNN are trained by the improv...

Abstract The sound quality produced by the door slamming event is one of the significant subjective parameters to evaluate the inherent quality of the vehicle. The vehicle door is mainly composed of fixed door panels and moving glass channels and the sound quality depends on these structural components. This paper proposes a numerical and experimental-based framework to evaluate the vibro-acoustic coupling value between the door panel system and the glass channel system in the door slamming even...

Abstract This study develops a topology optimization approach for design of carbon fiber reinforced plastic (CFRP) laminated components with different failure criteria to reduce the risk of structural failure. The discrete material and thickness optimization (DMTO) method is presented to parameterize the design variables of thickness and orientation of CFRP composites, which is driven by the Method of Moving Asymptote (MMA) algorithm. A large number of local constraints associated with the failu...
