摘　　要：通过接触单元数值模拟啮合齿的接触过程,采用5%最大主应变准则,建立了基于整体有限元分析的齿啮式快开压力容器塑性载荷计算方法。设计和工程应用表明,按该方法设计的容器满足结构强度和寿命要求。By considering the contact between the teeth and utilizing the face to face contact model with contact element and coulomb friction model,a computing method for plastic load of tooth-locked quick actuating pressure vessel based on finite element stress analysis and the 5% maximum principal strain rule have been developed. Many engineering designs see these pressure vessels can meet the requirements of strength and fatigue life.
