| Abstract: | The piezoelectric stack actuator is one of the key parts for high-pressure common rail piezoelectric injector.For the piezoelectric stack actuator,the finite element model was built and was verified by the experiment.In addition,the stress and its produced displacement under different preloads were simulated and analyzed.Finally,the matching and assembly parameters were determined.The results show that the built model is necessary for the design,manufacture and testing of piezoelectric stack actuator. |
| Keywords: | piezoelectric stack actuator FEM high-pressure common rail fuel injector simulation |
