An Articulated Rigid Body Motion Control Device Used in Underwater Large Pulse Width Explosion Experiments

Abstract

The invention belongs to the technical field of model experiment target cabin design experiments and testing, and in particular relates to an articulated rigid body motion control device applied to underwater large pulse width explosion experiments. The invention replaces the traditional buoy with a circular water tank, which is convenient to adjust the floating height, effectively reduces the problem of the up and down swing of the traditional buoy, controls the rigid body movement and displacement of the whole device, and can reduce the impact of shock waves on the device. In the present invention, the circular water tank and the annular water tank are connected by a tripod and a one-way hinge, so that the distance between the two can be easily adjusted; the wire rope is made of flexible material, and its flexibility is used to reduce the impact of the instantaneous explosion on the annular water tank. The invention is convenient to adjust the positional relationship between the explosive and the hull. Compared with the traditional floating box, the annular water tank can make the shock wave pass through the middle and reduce the impact of the shock wave on the experiment; the plate frame provides counterweight to reduce the huge shaking caused by the explosion shock. .

Description

technical field [0001] The invention belongs to the technical field of model experiment target cabin design experiments and testing, in particular to an articulated rigid body motion control device applied to underwater large pulse width explosion experiments. Background technique [0002] Ships will inevitably be attacked by various weapons during their service, and the impact resistance of the hull and its mechanical and electronic equipment is an important consideration in the design of ships. In particular, the impact damage caused by ships under underwater explosive loads, involving various nonlinear problems such as materials, motion, and geometry, as well as many uncertain factors, has always been the focus of research on ship vitality. In order to accurately simulate the damage characteristics of ships under underwater explosion loads, many previous studies have used scaled model experimental devices to study the impact damage mechanism of underwater explosions to sh...
