摘　　要：侧门是闸板防喷器中的关键部件。建立了闸板防喷器侧门的三维实体模型,用Solidworks有限元分析软件对侧门进行了承载能力分析,考虑了材料的弹塑性特性,分析了侧门密封圈应力应变情况,同时,在侧门承受35MPa均匀压力作用下,得出了原始侧门与改进后侧门的应力、应变和内轮廓的变形量,最后提出相应的分析及其改进措施。为验证设计的可靠性、合理性及进一步改进设计提供了依据。The side-door is a key component in ram preventer.A 3-D model of ram preventer side-door was established.The carrying capacity of ram preventer side-door was analyzed by using Solidworks software and the elastic-plastic character of material was considered.Stress distribution of sealing ring of side-door was analyzed.At the same time,under 35MPa uniformity pressure,the stress,the strain and inner-figure deformation between original side-door and modified side-door were obtained,the corresponding modified measures were put forward finally.It provided theoretical basic for proving the reliability and rationality of ram preventer side-door design.
