Abstract

Abstract

Based on the shear test of two types(Ⅰ and Ⅱ) of shape memory alloy pseudo-rubber(SMAPR) bearings, the effects of loading frequency, loading amplitude, processing technology and pre-compression stress on its shear properties of its non-forming direction were studied. In addition, the self-recovery through temperature-rising and subsequent mechanical properties were investigated for the SMAPR specimen with residual deformation. The results showed that the shear properties of type Ⅰ and Ⅱ SMAPR bearings were stable, and the equivalent damping ratio increased with the increment of shear amplitudes. The shear stiffness and energy dissipation capacity of SMAPR isolators could be greatly improved by applying pre-compression loads. The residual strain of the two types of specimens could both be eliminated through temperature-rising, and the mechanical properties of type Ⅰ specimens were consistent with those before temperature-rising, which had good repeatability.
