摘　　要：人-车的相互作用对汽车的操纵稳定性有重大的影响,而人椅系统的低频多向振动特性的研究对于人车相互作用的分析具有重要的意义.为此本文中建立了人椅系统的12自由度三维动力学模型,并利用多向振动试验台架在0.5-5Hz频率范围内进行了人椅多向振动试验,识别出36个低频多向振动特性参数.结果表明：提出的低频多向振动试验及参数识别方法可行,其参数可表征汽车人椅系统的低频多向振动特性.Human-vehicle interaction has significant effects on the handling stability of vehicle and the study on the low-frequency multi-direction vibration characteristics of human-seat system,main interface of human- vehicle interaction,has great significance in the analysis on human-vehicle interaction. In view of this,a 12 DOF 3D dynamics model for human-seat system is established,and a human-seat multi-direction vibration test in a frequency range of 0. 5-5Hz is conducted on a multi-direction vibration test bench,and 3 6 parameters of low- frequency multi-direction vibration characteristics are identified. The results show that the scheme proposed of low frequency multi-direction vibration test and parameter identification is feasible and the parameters identified can represent the low frequency multi-direction vibration characteristics of vehicle human-seat system.
