Method for rapidly calculating supporting force load range of shock absorber of large optical machine assembly

The invention provides a method for rapidly calculating a supporting force load range of a large-scale optical machine assembly shock absorber, and belongs to the technical field of equipment support calculation and analysis. According to the method, statics equilibrium equations of a system are established, and all equations are written into a matrix form. Random sample generation and exhaustive sampling are carried out on the rigidity value of the shock absorber through programming, random mounting surface height is synchronously generated during sampling each time, and supporting force in each state is obtained through calculation. And then processing all the calculated supporting force values to obtain a change range and a random distribution rule of the supporting force, and providing important data support for checking of the bearing platform. According to the method, the supporting force can be quickly calculated when the rigidity of the shock absorber and the height of the mounting surface deviate, th
