Numerical simulation of brush seal tests

A numerical analysis of deformation the brush seal wire package as part dynamic rotor&stator system gas turbine engines is describes. The estimated definition reaction force based on solving contact problem interaction bristles with each other, rotor and rear plate case, taking into account action distributed flow pressure. Comparison results obtained data well-known experimental studies. According to calculations, it was noted that accounting spatial elements significantly affects value and, accordingly, rigidity. In presence a pressure drop compaction, calculations simplified half-analytical model deflection one according flat bending console straight beam, differ in order. It necessary take this effect when calculating wear forecast its effectiveness course operation. characteristic feature dependence from magnitude displacement hysteresis "load - unloading" cycle due friction system. impact increases scope loops changes shape. On scale loop also strongly coefficient pair "schedules rotor". dependences tension / (hysteresis loops) allow you clarify calculated mathematical after testing stand.
