Hi,
I have puzzled over this phenomenon for quite some time.
It reminds me of the design of my favourite car of all time, the 1967 Peugeot
404 KF2, with Kugelfisher Fuel injection, just 1618cc and 100mph. My Q car.
When the 404 was first constructed, reports are that it was noisy and had
bad vibration. By the use of isolating devices and insulation the noise was
sorted out.
The solution to the residual vibration was interesting. There are two
rectangular cubic steel weights (about 3 times the volume of an old regular
match-box) attached to the rear of the gearbox where the drive-shaft exits,
and they are attached by separate and different-weight rubber blocks.
So Olympus technicians recommend using human arms and hands to
simulate this sort of solution. I wonder what a proper engineering solution
might be.
