| 摘要： | The important part of wheel life assessment problems is the accurate determination of the tire/wheel interface pressure distribution under various loading conditions. A combined analytical/experimental methodology for obtaining this pressure distribution was developed. The principal analytical tool in this methodology is the finite element program ANTWILL (Analysis of Tire Wheel Interface Loads) which recovers the pressure distribution given a number of experimental strain measurements on the wheel. The major activity consisted of a study of the F-16 Block 30 and the Block 40 main landing gear wheels to determine the optimal number and location of the strain gages for subsequent experiments. Experiments to be conducted will record strains at the specified locations and this data will be used to determine tire/wheel interface pressures.
