Brake Hydraulic System Resonance Analysis 975504

Resonance frequencies and the associated pressure amplifications of a typical hydraulic brake system have been studied. Solutions to suppress the pipeline natural frequencies and pressure amplifications were obtained. Preventing the natural frequencies of a brake hydraulic pipeline from matching with the landing gear natural frequencies would minimize landing gear related accidents and avoid brake hydraulic system performance at abnormal resonance conditions. Prevention of the matching frequencies will reduce the aircraft stopping distance.
