摘要为准确评估动态升温过程中结构是否安全，基于经典赫兹接触理论、旋转动力学以及碰撞冲击理论，采用数值仿真方法对快关蝶阀分别进行瞬态热-结构耦合分析与瞬态动力学分析研究，对比研究了不同升温速率、不同关闭时间及不同密封面宽度对快关蝶阀结构强度及阀座密封性能的影响规律。研究表明：快关蝶阀的最终热应力和阀座密封面接触压力均随着升温速率的增大而增大，当阀门内壁升温速率小于0.225℃/s时，阀门的结构强度及密封可满足要求；分析快关蝶阀瞬间冲击速度以及快关过程总位移量，并与理论推导得出的数值对比，误差均在5%以内，快关冲击对蝶阀蝶板的影响程度大于阀座，进一步研究得出了冲击速度、撞击面积关键参数对阀门冲击的影响规律。

Abstract：In order to accurately assess whether the structure is safe during the dynamic heating process, based on the classical Hertzian contact theory, rotation dynamics and collision and impact theory, numerical simulation methods are used to conduct transient thermal-structural coupling analysis and transient dynamics analysis of the fast-closing butterfly valve. The effects of different heating rates, different closing times and different sealing surface widths on the structural strength and seat sealing performance of the fast-closing butterfly valve are comparatively studied. Research shows that the final thermal stress and the contact pressure of the valve seat sealing surface of the fast-closing butterfly valve increase with the increase of the heating rate. When the heating rate of the inner wall of the valve is less than 0.225℃/s, the structural strength and sealing of the valve can meet the requirements ; Analyze the instantaneous impact speed of the fast-closing butterfly valve and the total displacement in the fast-closing process, and compare with the theoretically derived values, the error is within 5%. The impact of the fast-closing impact on the butterfly valve disc is greater than the valve seat. The impact law of impact speed and impact area key parameters on valve impact is shown.

Key words： fast closing butterfly valve transient heat seal heating rate impact velocity impact area
