| description | The invention discloses a connecting structure rigidity refined modeling method. The method comprises the steps that the fractal dimension D and the fractal roughness G of a connecting structure contact surface are obtained; establishing an expression of the normal total load P of the contact surface based on D, G and the maximum contact area aL of the micro-bulge on the contact surface; obtaining the value of the normal total load P of the contact surface, and obtaining aL according to the expression of P; and establishing an expression of the connection stiffness Kn, and substituting aL into the expression of the connection stiffness Kn to obtain the stiffness of the connection structure. The calculation precision of the rigidity of the connection structure is improved, and the method is particularly suitable for a pre-tightening connection structure in a mechanical system.
