Abstract :
Duo to the limitation of the gear-rack´s structure profile for an aircraft slat, the maximum stress value got from test is not the value under actual load. In this paper, based on finite element model of gear-rack built by analysis software ABAQUS, the maximum stress value of gear-rack is determined by force analysis. Thus the strength of the gear-rack is checked, and finally the fatigue life is estimated. At the same time, strength test of gear-rack shows that calculation results and test are well consistent. This method can provide a foundation for the design optimization and reliability design of gear-rack for aircraft slat.
