摘要
用Pro/E建立公称通径为150 mm、压力为2.5 MPa的天然气球阀的密封装配图,依据轴对称原则,将其1/4导入ANSYS软件中。用双线性强化材料模型来模拟阀座,用刚体材料模型来模拟阀芯,采用面面接触有限元分析,以理论得出的平均密封比压值为基础来计算真实密封比压分布规律。
In this paper, we establish the sealing assembly model of a natural gas ball-valve by Pro/E, whose nominal diameter is 150 mm and nominal pressure is 2.5 MPa. Based on axisymmetric principle, we import one quarter of the model to ANSYS software. Simulating valve seat with bilinear kinematic hardening material model and valve core with rigid-body material model, using area-area contact finite element analysis, based on the average sealing pressure which comes from theoretic formula, we calculate the actual distribution of the seating pressure.
