Based on the mechanic vibration system's characteristic that it's elastic forces are only de pendent on deformations of elastic elements and damping forces only on relative velocity of damp ing elements,a new equivalent linearization technique to a class of non-linear multi-degree of freedom system's random vibration is established in this paper. Because its physical meaning is clear and its calculation is simple the method is an effective way for dealing with random vibration of non-linear multi-degree of freedom systems.
