Abstract:

Curvature mode theory was introduced to the damage identification of a rear axle of a car.The modal test analysis of rear axle was done.Results shows that the change of curvature mode shape has an obvious effect on identifing the local damage.The study results provide a practicable research method for structure damage identification of automobile components .

Key words:curvature mode; damage identification; modal analysis; rear axle
