Power matching of flying cars during takeoff stage based on dual-mode driving

More Information
  • 摘要:

    针对折叠翼飞行汽车起飞阶段的动力匹配问题,研究了基本的动力控制策略,通过理论计算分析了起飞阶段双模式驱动特性,提出了最佳切换时刻的概念。对某型飞行汽车传动系统进行了动力匹配计算,并以该飞行汽车参数为基础,在Simulink中建立了不同工况下的行驶仿真模型,对起飞阶段行驶状态进行了仿真分析,给出了基于双模式驱动的动力匹配方案以及最佳切换时刻的选取原则。计算结果表明,通过采取双模式驱动,起飞加速时间缩短22%,起飞滑跑距离缩短13%。进一步对传动系统参数、整车设计参数以及发动机输出特性进行了优化分析,分析计算结果给出了各参数变化对起飞动力性能的影响。
