For piping that is already installed, the tutorial will show the end user how to screen branch lines for susceptibility to fatigue failure and reduce or eliminate the vibration problems by adding clamps, changing the piping diameter, or changing the number or type of valves.
Many experts working in the field of vibration analysis will agree that resonance is a very common cause of excessive machine vibration. Resonance is the result of an external force vibrating at the same frequency as the natural frequency of a system.
The vibration can be caused by the bass generated by the stereo or simply by driving a less than perfect vehicle on a less than perfect road. This page will help you to identify the cause and will help you eliminate it to a point where it's no longer a problem.
