基于AMESim的液压混合动力车辆建模仿真研究

在阐述并联式液压混合动力车辆的结构原理及液压系统参数设计的基础上,利用AMESim创建了整车模型。根据液压混合动力系统的工作特性,以改善车辆燃油的经济性为目标,提出了基于车辆扭矩需求的发动机和液压泵/马达扭矩控制策略。仿真结果表明:该混合动力系统能合理控制扭矩分配,实现不同工作模式的平顺切换,在满足车辆动力性能指标的前提下,有效地提高了燃油的经济性。     

The snowball phenomenon: the US Marine Corps,military mythology and the spread of hybrid warfare theory

ABSTRACT

This article reviews the book by Ofer Fridman and seeks to situate the strategic debate on hybrid war in the context of debate on the US involvement in Iraq. It points to intellectuals from the Marine Corps having a significant role in the initial development of the hybrid warfare concept at a time of some reservation in US military circles over COIN strategy as this was set out in the field manual FM3-24. Thereafter, the hybrid war concept rapidly spread and became a conceptual device used to explain Russian strategic intentions in the aftermath of the invasion of Ukraine in 2014.
