以HR模型神经元为基础,研究了非对称结构耦合神经元系统的特性。结果显示,非对称时滞耦合下的系统同步的时滞范围与耦合强度C呈正相关变化,过强的耦合关系对神经系统的活性具有明显的抑制作用,系统的完全同步主要发生在相同时滞对称耦合的情况下,其它的同步类型主要是近似完全同步和相位同步等,时滞差异并未使得两个耦合HR神经元各自的峰峰间期分岔图明显不同,因此,耦合神经系统对时滞反馈虽然敏感,但非对称时滞反馈与
We studied a multi-objective optimal design of three different frame vibration control configurations and compare their performances in improving the lateral stability of a high speed train bogie.The
轮胎的刚度特性和阻尼特性对汽车操纵稳定性、乘坐舒适性及振动噪声等能产生显著影响.但是对轮胎刚度的研究主要集中在径向刚度,对侧向和切向的动态刚度研究较少.因此有必要对其进行深入实验研究,并且对轮胎变形量、充气压力及激励频率对轮胎侧向及切向动态刚度的影响进行分析.在自制的试验机上以不同频率、不同幅值的正弦激励对载重汽车子午线轮胎10.00R20进行加载,测试轮胎侧向及切向变形及动载荷.分别建立了轮胎侧

针对判断列车脱轨问题,本文评述了近些年来国内外的研究进展情况。首先分析了传统判断脱轨的方法,发现传统利用脱轨系数与轮重减载率的车辆脱轨评价方式都是从轮轨间受力情况方面加以分析,在进行脱轨判定时存在严重的误差与不足。在此基础上提出了一种基于轮轨相对位移的脱轨预测方法。通过在ADAMS/Rail中建立单车模型,对轮轨作用关系和列车安全性分析研究,推断出列车安全性与轮轨几何位置存在关系。经过仿真实验提取
