Description
油圧流体の遷移、チェックバルブの開閉、ショックアブソーバの移動遷移点での摩擦(これらは圧力波を発生する)により励振が引起こされる。これらの圧力波はピストンロッドの質量を励振し、該質量はその共振周波数で振動する。ブリードによる内部油圧減衰により、生じるピストンロッド加速レベルおよび伝達力が低下される。図7には、特定ショックアブソーバについての測定共振および模擬共振が示されている。図7は、共振周波数は約320Hzにあることを示している。NVH性能を向上させるには、この共振周波数を低減させるか、なくすことが望ましい。
ここで、Km、KdおよびKDVAは、それぞれ、アッパーマウント、ショックアブソーバ20および動的振動アブソーバ70の複合動的スチフネスであり、MrodおよびMDVAは、ピストンロッド34および動的振動アブソーバ70のモード質量である。
