21605 電磁石と非線形ばねを用いた低摩擦エンジン動弁系の開発とジャンプ特性(振動解析とその応用I,OS.2 振動解析とその応用)

In this research, a new type valve system using a conical spring and an electromagnetic actuator was developed: This system uses a conical spring, and is a low torque in a low-speed rotation. As a result, the energy loss in a low-speed rotation is decreased. However, the jump and bounce phenomena happen in the high-speed rotation region. Those are suppressed by using an electromagnetic actuator. It was confirmed to be able to decrease the load torque by using a conical spring in the experiment. Moreover, it was confirmed that the jump and bounce phenomena were suppressed by using the present electromagnetic actuator.
