随着新能源汽车的发展和普及,针对其电池系统碰撞安全研究的重要性日益凸显。高压线束作为新能源汽车高压电气系统的关键零件,研究其在碰撞工况下的电安全性能尤为重要。本文基于电池系统在碰撞工况下其高压线束可能遭受的典型挤压外载,选取直径15.8 mm的线束设计了D5柱面和V60楔面两种工况动静态挤压试验,试验过程中实时监测冲头与线束内部导体之间短路的发生,并对护套、绝缘层、导体3种组份材料进行拉伸、压缩等试验标定相应材料模型。通过线束结构试验和组份材料试验分别标定线束的单组份均质化模型和导体-等效绝缘层双组份模型。研究结果表明:线束在机械载荷下有很强的动态效应,动态下的力学响应升高。线束的短路行为与外载工况、加载速度高度相关。两种高压线束仿真模型利用单元删除来预测线束短路的仿真结果与试验结果基本一致,两种模型均可准确地预测线束在挤压工况下的短路风险。 相似文献

高低压线束耦合是电动汽车电磁兼容中需要重视的骚扰问题之一,因此在设计初期,汽车高低压线束电磁兼容设计非常重要。本文主要对电动汽车高低压线束耦合特性进行分析,在FEKO软件中建立高低压线束耦合模型及整车模型,通过S参数对高低压线束的耦合特性进行了仿真分析。并在实车进行了测试,仿真及测试结果表明高低压线束不同的布置方式线束的耦合特性也不同,可以通过适当拉大线束间距和在线束间增加金属结构降低高压骚扰源线束对低压线束的影响。这为整车设计开发过程中选择合理的高低压线束布置方式奠定基础。 相似文献

A combination of experimental and numerical methodologies is proposed for the investigation of knocking in spark ignition
engines to aid in better understanding the physical and chemical processes that occur and to exploit the capabilities of a
developed computational tool. The latter consists of a thermo-fluid dynamics model, which is part of an advanced 1-D fluid
dynamics code for the simulation of the entire engine, and a complex chemistry model, which can be embedded into the thermo-fluid
dynamics model using the same integration algorithm for the conservation equations and the reacting species. Their mutual
interaction in the energy balance will be considered. The experimental activity was carried out in the combustion chamber
of an optically accessible, single-cylinder P.F.I. engine equipped with a commercial head. The experimental data consisted
of optical measurements correlated to the combustion and auto-ignition processes within the cylinder. The optical measurements
were based on 2-D digital imaging, UV visible natural emission spectroscopy and the chemiluminescence of radical species (OH
and HCO). The engine parameters, the pressure signals of the related data and optical acquisition are compared on an individual
cycle basis in the simulation by running the engine at a constant speed and varying the spark advance from normal combustion
to heavy knock conditions. 相似文献

In this article a theoretical investigation of the dynamics of a railway bogie running on a tangent track with a periodic disturbance of the lateral track geometry is presented. The dynamics is computed for two values of the speed of the vehicle in combination with different values of the wavelength and amplitude of the disturbance. Depending on the combinations of the speed, the wavelength and the amplitude, straight line forward motion, different modes of symmetric or asymmetric periodic oscillations or aperiodic motions, which are presumably chaotic, are found. Statistical methods are applied for the investigation. In the case of sinusoidal oscillations they provide information about the phase shift between the different variables and the amplitudes of the oscillations. In the case of an aperiodic motion the statistical measures indicate some non-smooth transitions. 相似文献
