| Abstract: |
| The finite element analysis technology was applied to the force analysis of the main interphone clamp of gas mask. When the external force was applied at the upper end and side end of the clamp at an angle of 45°，respectively，the stress states of the clamp under different temperatures and stress conditions were
obtained，the maximum allowable forces and maximum use forces of the clamp at different temperatures and positions and their change laws were determined. This study provided a reference for the design of the clamp. |
