| 抄録（英） | To enhance internal combustion engine performance, this study focuses on developing an electric valve drive system utilizing linear actuators for intake and exhaust valve control. The linear actuator, comprising a movable coil and a fixed permanent magnet, operates based on the principle of the Lorentz force. Unlike traditional magnetic circuits, this actuator employs five permanent magnets with different magnetization directions to concentrate the flux on the coil. In this study, multiple models with varying ratios of these permanent magnets were created and analyzed using finite element analysis conducted with the JMAG software to investigate the thrust characteristics during the reciprocating motion of the actuator. The vector plot of the magnetic flux density shows that the magnetic circuit is predominantly composed of permanent magnets. The average thrust at a 10mmdisplacementwas approximately 107Nin the largest model. Future studies will aim to design actuators with increased thrust capabilities. 翻訳 |
