基于SAM的中国人群乘用车驾驶座椅位置设计研究

Driver’s Seating Position Design of Passenger Car for Chinese Population Based on SAM Model

摘要: 随着国内各车企乘用车设计水平的提升，设计手段已经由逆向开发转到正向设计阶段，同时中国经济的高速发展，中国市场已经成为乘用车主战场，针对中国人体的乘用车正向开发至关重要，乘用车座椅行程长度设计及行程分配决定了目标人群人体舒适性及内部空间布置，目前国内外车企设计规范依旧是基于美国人体SAE设计标准，因此，本文将基于中国人体尺寸提出适合中国乘用车驾驶员座椅行程长度正向设计方法，同时使用人机柔性台架进行了验证，为座椅行程正向设计提供了理论上的参考。

Abstract: With the improvement of passenger car design level in domestic automobile enterprises, the design method has changed from reverse development to forward design stage. At the same time, with the rapid development of Chinese economy, the Chinese market has become the main battlefield of passenger cars, and the forward development of passenger vehicles for Chinese human body is very important, and the track length design and travel distribution of passenger car seats determine the human comfort and internal space layout of the target population. At present, the design practice of domestic and foreign car enterprise is still based on the human body of the United States SAE design standard, because of the difference of human body size between China and the United States and the SAE design standard. Therefore, based on the Chinese human body size, this paper puts forward the forward design method of the seat track length suitable for the driver of Chinese passenger car, and uses the man-machine flexible bench to carry on the inspection at the same time, providing a theoretical reference for the forward design of the seat track.
