中文摘要： 重型汽车后防护系统能够有效减少乘用车与重型汽车追尾钻入事故所造成的损伤，是当前商用车研究领域的热点和前沿。但现有后防护装置大都与车架刚性连接，难以实现阻挡刚度、碰撞相容性及整车通过性的协同优化。本项目拟通过仿生工程与车辆工程的学科交叉，以人-车-环境耦合系统为研究对象，采用多元耦合仿生理论设计重型汽车智能集成后防护系统。通过生物耦合理论对人-车-环境系统进行耦合机理分析，建立多源信息融合智能安全预警策略；模拟生物应激反应设计机电一体化主动控制系统，根据风险状态智能调节后防护装置；探索羊角良好吸能特性及结构强度的形成机制，构建形态-材料-结构-构型-功能一体化多元耦合仿生模型，设计仿羊角跨尺度特性后保险杠，建立完整的重型汽车主被动智能集成后防护系统，实现整车性能多目标协同优化。本项目的开展，将探索出一套全新的汽车安全系统仿生学设计体系，有效减少交通事故伤亡，全面优化人-车-环境闭环系统性能。

英文摘要： The rear under-run protection devices （RUPD） for heavy truck, which could effectively decrease the injuries in the event of under-run, has become a focus in current commercial vehicle research. Most of the existing RUPDs, however, are rigidly mounted on the frame, which means it is hard to satisfy very well the required strength, stiffness, impact location, and the trafficability of heavy trucks. The objective of this project is to design the intelligent integrated rear under-run protection system for heavy truck based on the multi-coupling bionics theory, in driver-vehicle-environment (DVE) coupling system, through combining vehicle engineering and bionic engineering. According to the biological coupling theory, the coupling mechanism of the DVE system is to be analyzed and the intelligent rear-end collision warning strategies based on multi-source information fusion are to be established. By imitating the stress response of creatures, the electromechanical active control system is to be designed, which could intelligently adjust the bumper automatically in light of the risk states. The mechanism of good capacities of energy absorption and structural strength of sheep horns are to be studied and a multi-coupling bionic model covering shape, materials, structure, configuration and function is to be established. On the basis of both the macroscale and microscale structures of sheep horns, a new concept of bumper is to be designed and an intelligent RUPD integrating active and passive safety is to be built so that the vehicle performance could be multi-objective collaborative optimized. Within the implementation of this project, a set of new bionic design system for vehicle safety system will be explored, which will effectively reduce the injuries and deaths when the accident occurs and greatly optimize the performance of DVE system.
