The invention relates to a rotary cylinder
model test device which comprises a supporting
tower. A cylinder rotatably sleeves the circumferential outer side of the supporting
tower; a driver is fixedly installed in the supporting
tower, a runner is installed at the output end of the driver, and the circumferential edge of the runner extends out of the supporting tower and is attached to the innerwall face of the cylinder. A rotating shaft is rotatably arranged on the upper part of the supporting tower, the upper end of the rotating shaft extends upwards out of the supporting tower, and a
rotating disc is installed at the end of the upper end of the rotating shaft and fixedly installed on the inner wall face of the cylinder in the circumferential direction; a
force balance is mounted on the bottom surface of the supporting tower; during use, the test device is installed on the wind tunnel test ground through the
force balance; a short cylinder is installed above the cylinder through afastener to obtain a rotating cylinder with a preset length-
diameter ratio, a driver drives a rotating wheel to rotate, the rotating wheel drives the cylinder attached to the rotating wheel to rotatethrough circumferential
surface friction force, the rotary cylinder integrally rotates, and therefore rotating torque is measured through a torquemeter, and lifting resistance is measured through a
force balance. The device is used for a rotary cylinder
model test, rotation is reliable and stable, and the test effect is powerfully guaranteed.
