【摘要】：目的分析自力式密封方式在摩擦系数、流体压力及密封间隙大小的作用下对密封圈的应力及等效压力的影响.方法利用ABAQUS软件建立O形密封圈对称模型,分析在不同的摩擦系数、不同密封间隙及流体压力下对应力及等效压力的影响.结果当摩擦系数大于0.3 MPa时,O形密封圈的应力及等效压力不再受摩擦系数的影响;O形密封圈的应力及等效压力将随着流体压力的增加而增加,但当流体压力大于2.0 MPa以后,O形密封圈的应力及等效压力分布及数值几乎无影响;间隙增大时应力分布区域增加,应力值也增大,等效压力逐渐降低.结论流体压力、摩擦系数对O型密封圈应力及等效压力的影响较大,密封间隙大小对密封圈的应力及等效压力也有影响.此结论在理论指导和实际应用上具有重要意义.
[Abstract]:Aim to analyze the effect of self-operated seal on the stress and equivalent pressure of seal ring under the action of friction coefficient, fluid pressure and seal clearance. Methods the symmetry model of O-ring was established by ABAQUS software, and the effects of friction coefficient, seal clearance and fluid pressure on stress and equivalent pressure were analyzed. Results when the friction coefficient is greater than 0.3 MPa, the stress and equivalent pressure of the O-ring are no longer affected by the friction coefficient. The stress and equivalent pressure of O-ring will increase with the increase of fluid pressure, but when the fluid pressure is more than 2.0 MPa, the stress and equivalent pressure distribution and value of O-ring will have little effect. When the gap increases, the stress distribution area increases, the stress value increases, and the equivalent pressure decreases gradually. Conclusion the influence of fluid pressure and friction coefficient on the stress and equivalent pressure of O-type sealing ring is great. The sealing clearance also has an effect on the stress and equivalent pressure of sealing ring. This conclusion is of great significance in theoretical guidance and practical application.
