Abstract
【解決手段】 能動型防振支持装置の可動部材28を往復動させるアクチュエータ41のアマチュア(可動コア)54を収納し、かつアマチュア54に接続された可動部材28が臨む密閉空間61の圧力を、密閉空間内61に配置されて該密閉空間61の壁部に形成した連通孔13cを介して大気に連通する可撓性の袋体64により略大気圧に維持するので、密閉空間61に塵や水が入り込むのを遮ってアマチュア54に作動不良が発生するのを防止しながら、密閉空間61に圧力変動が発生しないようにして可動部材28の中立位置を安定させ、アクチュエータ41による可動部材28の制御を精度良く行うことができる。

Description
Tq=I×dω/dt
により演算する。このトルクTqはクランクシャフトが一定の角速度ωで回転していると仮定すると0になるが、膨張行程ではピストンの加速により角速度ωが増加し、圧縮行程ではピストンの減速により角速度ωが減少してクランク角加速度dω/dtが発生するため、そのクランク角加速度dω/dtに比例したトルクTqが発生することになる。
