Abstract

In order to reduce excessive vibrations in mechanical systems there are used different absorber types. The shape memory alloys (SMA) are more and more frequently used in semi-active vibration control systems. Such an absorber changes its stiffness when heating or cooling. This type of material has nonlinear characteristics, which causes difficulties in modeling process. This paper presents the process of modelling and determination dynamic characteristics of the SMA vibration absorber. The numerical model of primary system with the absorber was created in APDL language, which is an internal ANSYS language. The SMA was modelled as nonlinear material, which is very important to obtain high-quality results.
