Mechanical device for determining the modulus and loss factor of a damping material based upon temperature and frequency

A mechanical device for providing a modulus value and a loss factor value for a selected damping material based upon temperature and frequency variables, which comprises:

• (a) a substantially planar, rectangular insert, which includes,
• (i) a front surface containing a graduated sequence of isotherms, and
• (ii) a rear surface containing plotted curves of modulus datapoint and los factor datapoint values for a damping material as a variable of temperature and frequency, and
• (b) a substantially planar, rectangular sleeve restrainably retaining the insert within a passage defined by the sleeve, and including,
• (i) a front panel containing, (aa) a rectangular temperature isotherm display window having a right side and a left side, (bb) a logarithmic frequency scale positioned immediately along one side of the isotherm window, and
• (ii) a back panel containing, (aa) a rectangular modulus/loss factor display window having a right side and a left side, (bb) a modulus scale positioned immediately along a first side of the modulus/loss factor display window for cooperatively interacting with the modulus curve so as to provide values for the datapoints represented by the modulus curve, and (cc) a loss factor scale positioned immediately along a second side of the modulus/loss factor display window for cooperatively interacting with the loss factor curve so as to provide values for the datapoints represented by the loss factor curve,
• (c) wherein the insert and sleeve are mated such that alignment of a temperature value from the temperature isotherms and a frequency value from the frequency scale by movement of the insert and sleeve relative to one another results in identification of the modulus value and loss factor value of the damping material at the aligned temperature and frequency values by the modulus/loss factor display window.
