摘要： 在发生车辆碰撞时，车辆内饰件要起到保护乘员的作用。该文利用1998年颁布的美国联邦机动车安全标准FMVSS201 (FMVSS，为美国联邦机动车安全标准，Federal Motor Vehicle Safety Standards and Regulations的缩写)，考虑到硬点、位置、内饰件材料、护钣厚度、加强筋等因素，建立了CAE(计算机辅助工程, Computer Aided Engineering)模型。对于护钣厚度、材料和结构三方面对内饰件碰撞的敏感性因素进行分析。用简化力学模型，分析了内饰件对乘员头部受力。分析方法可用于改进车辆内饰件的设计。

Abstract: The vehicle interior is playing a vital role in occupant protection when the vehicle collision happens. According to the FMVSS201 (Federal Motor Vehicle Safety Standards and Regulations,FMVSS) released by United States in 1998, a CAE (computer aided engineering) model was built including the impact location, hard point, material property, thickness, and the ribs of vehicle interior. The sensitivity of interior impact to the material property, thickness, and structure of the interior was studied. A simplified mechanical model was used to analyze the force of occupant’s head impact to the interior. The analysis method can be used to improve the design of the vehicle interior.

Key words: vehicle collision, occupant protection, vehicle interior, occupant head injury
