There is a reason the factory driveshaft was 2 piece. And its exactly because shorter shafts have a much higher critical speed. While pricey, the Mark Williams setup gets you both drastically increased strength and a very high critical speed. You won't find a single shaft from anybody that will do both as well.

The relation between speed and crashes . Summary The exact relation between speed and crashes depends on many factors. However, in a general sense the relation is very clear: if on a road the driven speeds become higher, the crash rate will also increase. The crash rate is also higher for an individual vehicle that drives at higher speed than the

critical speed analysis was carried out within a given operating speed range. Vibration sources of these highspeed shaft couplings were modeled, and the corresponding natural frequencies were determined, and, as a result, it was confirmed that the critical speed was close to the operating speed of 1,200 rpm

Nov 27, 2015· What is meant by the term critical speed and why it can be a problem on ships ? The critical speed of a shaft occurs when the shaft rotational speed is at or close to resonant conditions. In this condition the torsional vibration of the shaft increases greatly, and will impose very high shear stress on the crankshaft.

Ball Screw Column Strength and Critical Speed End Fixity. End fixity refers to the method by which the ends of the screw are supported. The degree of end fixity is related to the amount of restraint of the ends of the screw. It is important to determine the proper end fixity in order to determine the appropriate screw size for a give application.
