To solve the problem of load distribution of multi-wheel and multi-strut landing gears， the landing gear loads of Aircraft IL 76 are surveyed， and the loads acted on landing gears during landing and turning on ground are analyzed. From the measured results， it is found that loads acted on the front main gears and on the rear main gears are equivalent during landing， and the spin-up loads are serious. Turning is the special load case of the multi-strut landing gears compared with that of conventional three-pillar landing gear. The direction of lateral loads acted on the front main landing gears are contrary to the turning center， which will constitute the moment to hinder the turning of aircraft and cause disadvantageous torsion to the fuselage， which is a new load situation that the three-pillar landing gear does not have. The lateral loads on the rear landing gears provide the centripetal force for turning. For the rear landing gears turning， it is the serious combination loads case of vertical and lateral loads. Turning increases vertical loads nonuniformity between the front and the rear main landing gears.
