Abstract: This paper is devoted to investigate the self-heating phenomenon inside high damping rubber bearings (HDRB). The rubber bearing tests were conducted at different ambient temperatures ranging from -30°C to 23°C in an environmental experimental chamber. A series of sinusoidal loading tests under a frequency of 0.5 Hz were carried out to investigate the rise of the inside temperatures in HDRB. The experimental results indicate that the temperatures inside HDRB are increased under sinusoidal loading, and these inside temperatures rise with the decrease in ambient test temperatures. Moreover, two mathematical equations are proposed to predict the inside temperatures of HDRB. The calculation of the equations is similar to the measured temperature in the center of HDRB.
