摘　　要： 基于模块化设计概念,研究了微型汽车车身加速度波形复现技术。论文对微型汽车平台衍生车型的正面碰撞车身加速度波形进行了等效简化,分析了关键结构吸能特性对车身加速度波形的影响;基于能量吸收和刚度等效,设计等效结构台车替代平台衍生车型研发过程中的骡子车,通过车身加速度波形验证试验表明台车设计方法可实现车身加速度的复现,该台车所测车身加速度波形满足乘员伤害相应模型仿真输入要求,有效提高了研发效率并降低了设计成本。 Based on modular design, the micro-automobile body acceleration waveform reproduction technology has been studied. The micro-automobile body acceleration waveform reproduction technology has been studied. By using equivalent acceleration waveform, the impact of key structural energy absorption characteristics on acceleration waveform was analyzed. Based on energy absorption and stiffness equivalence, the design of equivalent structures trolley was to replace the mule cart during the development process of platfarm derivative models, and frontal crash test results showed that test methods can achieve reproducibility body acceleration, and frontal crash test results showed that body acceleration wave forms measured by the trolley meet the input requirements of occupant injuries corresponding simulation model, which can effectively improve the efficiency of research and development.
