1. It is 1. a kind of based on the bolt-connection panel stiffness computational methods for dividing shape extended model, it is characterised in that:

  • Comprise the following steps:

    Step 1:

    Based on WK fractal models, single micro-bulge summit on rough surface is contacted with rigid plane expand to micro-bulge withRigid plane side contacts, establish side contacts and place an order micro-bulge normal contact stiffness model;

    Step 2:

    Using micro-bulge size distribution density function, the total contact stiffness mould of one normal direction of faying face dimension under side contacts is extendedType;

    Step 3:

    It is hardened that pretightning force, material properties parameter and the fractal parameter of acquisition of joint bolt gusset piece calculate bolt-connectionConjunction face rigidity, with reference to gusset piece substrate Rigidity Calculation bolt-connection panel stiffness.
