为分析气动式输弹机密封装置的密封性能,建立气动式输弹机密封装置的有限元模型,对比分析O形和X形密封圈的密封特性,并重点分析初始压缩量、气体压力、摩擦因数和活塞运动速度对X形橡胶密封圈密封性能的影响。结果表明:X形橡胶密封圈比O形更适合气动式输弹机密封装置;初始压缩量对X形橡胶密封圈的密封性能影响较小;摩擦因数和活塞运动速度是X形橡胶密封圈动密封特性的重要影响因素。
In order to analyze the sealing performance of the pneumatic rammer sealing device, the finite element model of the pneumatic rammer sealing device is established. The sealing characteristics of the O-ring and the X-ring are compared and analyzed. The initial compression, gas pressure, friction Effect of Factors and Piston Velocity on Sealing Performance of X - shaped Rubber Seals. The results show that the X-shaped rubber sealing ring is more suitable than the O-shaped sealing device for the pneumatic rammer. The initial compression has little influence on the sealing performance of the X-shaped rubber sealing ring. The friction coefficient and the piston moving speed are X-shaped rubber sealing rings Sealing characteristics of the important factors.
