In this paper, we report a set of vibration transmission experiments that are conducted to investigate how the pseudoelasticity of shape memory alloys (SMAs) affects the transmissibility characteristics of a spring-mass system, where a shape memory alloy rod is used as a spring. The tests are conducted by subjecting the SMA bar under tension- compression and under bending. The test results indicate that compared with ordinary alloys, SMAs have a much higher damping. Most importantly, the damping property depends on the amplitude of the responses indicating that the spring-mass system is nonlinear. Furthermore, the high damping property persists to the high frequency limit (above 1 KHz) permitted by the equipment setup.
