Compressive Property of Knitted-Dapped Metal Rubber at Different Temperatures

Static and dynamic compression tests at different temperatures (25, 100, 200, 300℃) were carried out on knitted-dapped metal rubber specimens. The effects of parameters, such as temperature, frequency and amplitude, on the compressive propery were studied. The results show that the stiffness and damping of the specimen decreased and then increased with the increase of temperature. The higher the density or the larger the deformation of the specimen, the more significant the effect of temperature on the static stiffness. With the increase of frequency, the dynamic stiffness of the specimen decreased slightly and the damping changed slightly. With the increase of the amplitude, the dynamic stiffness of the specimen decreased and the damping increased.
