Abstract :
The configuration and working principle of dual pressure common rail system (DPCRS) were introduced. In order to promote the performance of the DPCRS, a magnetostrictive actuator was designed. The finite element model of the actuator´s magnetic field was built up, the influence of control rod material on the distributing of the magnetic field was calculated, then experiment study was done. The results proved that the relative permeability of the actuator´s control rod should be smaller than that of the magnetostrictive material to avoid the magnetic flux be short., The magnetostrictive actuator has the characteristics of quick response, great output force, convenient drive.
