The relationship between modal displacement and modal strain and the degree of cracks in the outer ring is analyzed separately, and the sensitivity of modal displacement and modal strain to crack damage is compared. Because there must be a corresponding strain mode corresponding to each displacement mode, they are two manifestations of the same energy balance state and their proportions are the same. Here, the sensitivity of modal displacement and modal strain to crack damage is compared by comparing the maximum modal displacement and the maximum modal strain. When the crack depth is less than 4.5mm, the displacement mode increases with the degree of damage, but the change is small; the modal displacement begins to decrease; the modal displacements of other orders do not change much with the increase of the crack depth; the modal displacements of each order After the fracture, they all increased significantly. When the structure is damaged, the displacement mode changes greatly when the crack position is at the mode node position.
