摘要：
This article describes an original and multipurpose experimental set-up for the analysis of complex linear and non-linear aspects of aero-elastic behaviour of beam cross-sections. The apparatus meets rigorous theoretical assumptions and allows very precise and quick adjustment of stiffness and mass of a cross-section, which is not always possible with the traditional "parallel spring-supported bridge" approach used by many researchers. The principal advantages are described together with key construction details. Examples of the large amplitude non-linear response are presented, to illustrate the capacity and usefulness of the stand.
