摘要

近年來，人們對汽車品質的要求日益增加，由最初的外型、內裝質感、操控性能到車體結構強度，無不成為消費者購車時的參考條件，而從消費者第一眼看見的是汽車的外型，再來就是進入車內時的感受，而開關門這項看似小的動作，卻可提供消費者評價一台車的品質的一大因素，在車門開關過程中，呈現出關閉音與關閉力兩種感受，而文獻研究表示通常緊密紮實的關門音以及順手的關閉手感通常為大家最想獲得的感受。
因此，近年來許多汽車廠也投入大量的心血在提升車門關閉的品質，當一輛車關門音不佳或車門難以關閉也都會成為消費者對於車輛品質的負面評價，進而降低購買意願。
本文將透過各車門關閉的要因分析、各項關閉阻力的介入，再以儀器進行實車測試並探討個因素的影響比例分析，針對各項便因修正後再進行驗證，作為後續車輛設計製造時的參考依據，最後期望新機構的設計，或建立資料庫以縮短開發時程。

Recently, car buyers are always looking for better quality of the car. Their selection criteria cover the appearance of the car, the interior texture, the handling performance, and even the strength of the body structure. For instance, people will consider not only the outside appearance of the car but also the feeling after they enter the car. However, there is another key factor that will also influence buyers’ decision that is the design and functionality of car doors. Although this seems not very important, the quietness and mechanics design of car doors truly enhances consumers evaluation result. In other words, people are seeking the tight closed sound and tight mechanics design during the door switch process.
Thus, in recent years, many automotive plants also put a lot of effort to further enhance the quality of the door design. That is because when a car door closing sound is poor or the problem with difficulty of closing door, the consumers will start to complain the quality of the vehicle, thus reducing the willingness to buy.
Through the analysis of car door closing factor, energy conversion, we can investigate the ratio of the factor and conduct the real car testing.
We can also take this article as a reference for the subsequent manufacture of vehicle design.
