摘要/Abstract

摘要：

通过文献研究和仿真分析，确定座椅后撞动态试验的条件输入，并提出相应的座椅强度和假人伤害的要求。所提出的试验方法和要求可应用于校车座椅国标修订，将静态抗后倾试验升级为动态试验，解决静态试验不能反映实际交通事故中的性能的问题，适应技术发展的需要。

关键词: 校车座椅, 抗后倾, 后撞动态试验

Abstract:

By means of literature research and simulation analysis， the condition input of seat rear impact dynamic test is determined， and the corresponding requirements of seat strength and dummy injury are proposed in this paper. The test methods and requirements proposed can be applied to the revision of the national standard for school bus seats and the static anti-backward-pitching test is upgraded to a dynamic one， so solving the problem that the static test cannot reflect the seat performance in actual traffic accidents and meeting the requirements of technological development.

Key words: school bus seat, anti-backward-pitching, rear impact dynamic test
