喷油器本体是喷油器的重要部件。为了保证喷油器的可靠工作，采用ANSYS有限元分析软件对喷油器在瞬间加、卸油的情况下，喷油器本体的应力和疲劳强度进行了仿真分析。分析表明，喷油器本体在分流道入口处存在应力集中。结果表明，倒圆可以降低喷油器体的应力，提高其疲劳强度。最后得出了圆角半径与应力集中和疲劳强度的关系。确保注射器本体的疲劳强度符合要求。
The injector body is an important component of the injector. In order to ensure the reliable operation, the finite element analysis made in ANSYS Workbench is used to simulate and analyze the stress and the fatigue strength of the injector body provided that the fuel loads and unloads instantly. The analysis shows that the stress concentrations of the injector body exist at the entrances of the split ports. It is found that the stress can be reduced, and the fatigue strength of the injector body can be increased by rounding. Finally, the relationships between the fillet radius and the stress concentration and fatigue strength are obtained. Ensure the fatigue strength of the injector body meets the requirement.
