Design and static analysis of landing gear shock absorber of commercial aircraft

Landing gear design is one of the prime and the most complex aspects of the design of an airplane. Landing gear is composed of various components which make it a complex system to design. Shock absorber is one of the important components that has to be designed such that it can absorb maximum of the kinetic energy during adverse conditions like impact landing and taxiing though bumps without any failure. This paper basically comprises structural analysis of a landing gear shock absorber model in static condition. A conventional shock absorber model is designed by using CAD software CATIA and then structural safety in static condition is analysed by using ANSYS. In this work, large commercial aircraft Boeing 787-8 is taken as problem field. Titanium alloy and High strength Stainless Steel two different materials are chosen for the analysis to check the behavior of stress and compare the strength of the model for both the materials. The result shows that the model of high strength stainless steel has lesser stress and deformation. (c) 2020 Elsevier Ltd. All rights reserved.

Automated summary

Landing gear design is a crucial aspect in aircraft design, with shock absorbers being one of the key components that need to be carefully designed. This study focused on the structural analysis of a landing gear shock absorber model for the Boeing 787-8 in static conditions, with results showing that the high strength stainless steel model exhibited lower stress and deformation.
