| 中文摘要: |
| 将有限元分析技术应用到防毒面具主通话器卡箍的受力分析中，分别在卡箍的上端和侧端斜向45°施力，得到卡箍在不同温度和受力情况下的应力状态，确定卡箍在不同温度和不同位置的最大许用应力和最大使用应力及其变化规律，这为卡箍设计提供了参考。 |
| 英文摘要: |
| 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. |
