Why is there a sweet spot (50-60mph) where a vehicle will shake when the alignment is off? How does the shaking start around 50/55 and get better after going over 60?
In: Engineering
The mis-alignment is a minor part of the situation. ALL rotating objects have what is know as a “Critical Speed” where they will vibrate, (or try to, if sufficiently mounted to prevent the critical speed vibration from causing physical movement). Even huge power plant turbines have a critical speed and the proper method of dealing with that specific speed is to accelerate quickly through it. Bad alignment just allows the critical speed to become quite noticeable.
