联轴器moment simulator是什么

如题，还有idle什么的，都是做什么用的

有知道的吗？

英文从字面上面看是时刻模拟器的意思，具体表示什么意思就不清楚了

When do you need a special moment simulator?
For high speed turbomachinery applications with relatively small
diameter shaft mounts – say 15000 rpm with 4 inch (100 mm)
shaft mounts - a reduced moment flexible element coupling is a
must to keep the rotor sensitivity to unbalance low.
When one of these rotors needs to be balanced at speed, it’s best
to simulate the effects of the coupling mass on the end of the
rotor. This is particularly important if the rotor has an extra long
overhang from the bearing or if the rotor will otherwise operate
close to its lateral critical speed.
A one-piece “dummy” hub can be used to simulate the coupling
mass and moment, but it’s just not the same as if the actual
coupling were mounted. It’s difficult to simulate flexible element
coupling parts with a solid piece of steel.
