The popularity of Web 2.0 and social networking has greatly promoted user interactions in Internet services and changed the service delivery model. As typical Internet service providers, traditional digital repositories are facing two increasing demands: introducing user participation and providing personalized services. For the former, annotating digital resources and sharing the annotations with...
This paper presents the dynamic characteristics of the fuel injection system in gasoline engine. Through AMESim software, it analyzes the pressure pulsations due to the excitation by the injector opening and closing with regular interval. The simulation model is validated by experiments. Then it compares the pressure pulsations of the system with and without damper. The results show that damper can...
This paper aimed at proposing a new hypocycloid mechanism to actually realize energy transformation between rectilinear motion and rotary motion. The 3D virtual prototype mechanism is presented and it's simplified to reduce the complexity of analysis. The kinematics and dynamics characteristics of this mechanism were studied. For obtaining motion characteristic of the parts in new mechanism, the motion...
