A Study of Contact Stress on Coatings of Wheel-Slide Using ANSYS

The main purpose of this research is to find a solution for the coating/substrate of the wheel-slide which is the key component of civil aircraft flaps and slats, firstly, the simulation test is designed based on wheel-slide’ s working environment. Further, stress analysis of the coating/substrate is researched, and the results are as the input parameters of the finite element model. Then the finite element software, ANSYS, is applied to simulate the contact stress of coating/substrate in wheel-slide, and the stress’s distribution of coating/substrate are analyzed under different load, different coating thickness, different elastic modulus ratio of coating and other parameters. So the stress field characteristics are gained to guide the conduct of modeling experiments. The results can be applied to explore the failure of mechanism coating/substrate system, and provide theoretical guidance to design the coatings.
