基于虚拟惯性台的刹车系统仿真研究

Study on Brake Control System Test Method Based on Virtual Simulation Experiments

针对传统的惯性台试验不具备带起落架刹车能力,无法开展多轮起落架系统刹车试验的不足,提出了一种能与试验室惯性台试验原理、方法相结合,又能克服传统的物理试验不足的虚拟惯性台试验方法。利用仿真软件建立了虚拟惯性台仿真试验模型,对模型进行了仿真分析,并与外场实测结果进行了对比。结果表明:仿真分析结果与实测结果较为接近,所建立的模型简易可行,可以方便开展带起落架的多轮起落架刹车系统虚拟试验。

With the lack of traditional virtual simulation experiments test don't have the capability with landing gear, which also can't be carried out several rounds of the landing gear brake system test, this paper proposes one test method which is combined with laboratory simulation experiments test principle and can overcome the traditional test method by the lack of physical test. Based on software MATLAB, the model of virtual simulation experiments are established and analyzed in the simulation. With the contrast of outfield test result, it shows that simulation analysis result is proximity to outfield test result. The model is simple and convenient to carry out brake system virtual test with multi-wheel landing gear.
