title: [Stress analysis of separators with different specifications].
abstract: OBJECTIVE
  To evaluate the shape and structure of different separators affecting the mechanical behavior.
  
  
  METHODS
  The stress of different separators was analyzed by ANSYS software. Various separators were meshed into one-dimensional solid elements and the material character parameters were inputted. The loads were added gradually.
  
  
  RESULTS
  The stress was related to the arm of force and the point of force application.
  
  
  CONCLUSIONS
  The force applied can be controlled by selecting different separators.
