Abstract
An apparatus for measuring the vibrational characteristics of a muffler and including a metal adapter having an internal cooling chamber. One end of the adapter is attached to a connecting member, such as a nut, that is secured to the outer surface of the muffler, while an accelerometer is mounted on the opposite end of the adapter and measures the vibrational characteristics of the muffler under operating conditions. A cooling medium, such as water, is continually flowed through the internal chamber of the adapter to minimize transfer of heat from the muffler to the accelerometer. The adapter is designed to maximize the cooling effect with a minimum increase in mass.
