“…There are also other studies concentrated only in prediction models to define the major contributors of the DCE. 5,12,13 Cousin et al 14 used Star-CCM+ solver to perform CFD analysis of cabin pressure during the door closure process. The numerical simulations showed good correlation with the measured results.…”

The prediction model for the energy contributors is studied to define the effect of door components. The model is validated by experimental measurements on produced vehicles. The correlation of the control results and the evaluation methods among the representative customers, appraisers and senior experts are performed and compared by objective energy measurements. The subjective evaluation aims to clarify real customer expectations in door closing process and carry it to new product development phase. This will also improve the competency of appraisers in final assembly approval zones. The energy contributors for boot swing door is numerically calculated and validated by experimental measurements in easy and hard-closing doors. Subjective evaluations in 45 vehicles with different closing energies were performed by three different groups as representative customers, appraisers, and senior experts. The results were evaluated by statistical tools. The major energy contributors were found as air binding, seal resistance and check strap both in the calculations and in the experiments. The results demonstrated good correlation between numerical model and objective measurements. Besides, the subjective evaluations showed parallel trends with objective energy measurements. The variation in customer evaluations is more than appraisers and experts. Customers are severer in the evaluations of hard-closing doors and more sensitive in 10° door closing angle. This is a unique study for rear boot swing door closing effort in an LCV model. The study contains both definitions of factors, components that contributes in door closing energy and subjective evaluations to correlate the closing behaviors of representative customers, appraisers, and senior experts. The output of the study would be used to improve the vehicle control plan (VCP) and design standards in new model development phase.

The seal deformation of automotive door is caused by the door compression forces, including non-linear elastic force and non-linear damping force. The working principles of them are analyzed and a new simplified analysis model is built. Based on the Bernoulli equation and the law of conservation of mass, the mathematical models are established to calculate energy consumption of the seal system. According to the analysis results, the energy consumption of non-linear elastic force and non-linear damping force are respectively 84% and 16% of the total energy consumption of the seal system. At last, the calculation data is compared with the test data and the error is less than 5%, so the calculation method proposed in this paper is observed to be accurate.
