Abstract: The present invention discloses an analysis method of a tensioning process of a fine mask plate. The analysis method, based on the simulation function of ANSYS software, finds an appropriate tensile force for stretching a fine mask plate and a corresponding actual counterforce applied to a metal frame before each fine mask plate is welded onto the metal frame through establishing a finite element model of the fine mask plate and a finite element model of the metal frame. The analysis process requires no physical tests, thereby effectively avoiding damaging the fine mask plate and further effectively saving the test cost.
