Abstract
The utility model relates to a statics experimental device and especially discloses a statics experimental device not only suitable for ship model floating condition adjusting experiment teaching and ship model inclination experiment teaching but also suitable for floating body model hydraulic performance testing researches. A ship model statics experimental device mainly comprises a statics water tank (1), a connecting frame (2), an attitude instrument (3) and a data acquisition analysis and processing part. The statics water tank is formed by connecting two symmetric segments of tank bodies through bolts. The side walls and the bottom of each tank body are bonded with glass walls through glass cement. The connecting frame is formed by welding an upper horizontal channel beam, a lower horizontal channel beam and vertical channel beams and fixed on the central position above the statics water tank. The attitude instrument is arranged on the connecting frame. The ship model statics experimental device can not only achieve horizontal swing motion and vertical swing motion of a model but also realize ascending and descending motion. Meanwhile, the arrangement of sector gears, angular displacement sensors and driving members and the selection of light aluminum materials make the attitude instrument have relatively small damping influence. The measuring precision is thus ensured.
