ABSTRACT: Based on the analysis of the total free energy of the liquid-bridge, several methods are presented to analyze the pull-off force of liquid-bridge. For the liquid bridge system with a large gap width, accurate solutions of a two-plates liquid bridge and a sphere-plane liquid bridge are given. In addition, the edge-effect resulting from the profile of the top solid in the liquid-bridge system is analyzed and calculated. It is proved by the subsequent tests.
