摘要
针对旅客列车发生纵向冲动时的判断标准缺乏统一性,进行了列车的纵向动力学分析以及人体敏感度分析。运用数字信号处理和虚拟仪器技术对采样数据进行了分析统计,归纳出了纵向冲动产生时的普遍性规律,并在研究的基础上提出了以加速度、频率和作用时间为依据的新的纵向冲动判断准则。实验表明,与传统舒适度标准相比,运用该准则进行人体的纵向舒适度判断更为合理与准确。
To solve the absence of the uniform rule for judging longitudinal impulse of passenger trains, the new judge rule composed of acceleration, inherent frequency and effect period is provided in this paper based on the research of the longitudinal dynamics of trains and human sensitivity. The genera pattern of longitudinal impulse was reduced through analyzing and concluding acceleration samples by digital signal processing and virtual instruments. Compared with traditional rules, the new rule is more rational and exact, which was proved by experiments.
