摘要：
Requirements for a frequency-dependent spring, with little hysteresis, and for a damping material with little change of modulus with frequency were investigated together, as frequency-dependence of modulus and hysteresis are closely related. Dynamic test data on a variety of polyester urethanes are presented and shown to be consistent with an amorphous domain structure. The hysteresis correlates well with the rate of change of modulus with frequency.
