A simplified calculation simulation device and simulation method for ship ice collision in water medium

Abstract

The invention discloses a simulation device for simplified calculation of ship-ice collision in a water medium which comprises a water tank, wherein a lifting support frame is arranged in the water tank; an ice body model is arranged on the support frame; a ship model is arranged in the water tank; a guide rail is arranged on the water tank; a towing device is arranged on the guide rail; the towing device is connected with the ship model through a towing truss, a pressure sensor is arranged at the top end of the ship, and the pressure sensor is sequentially connected with a charge amplifier, amulti-channel signal collector and a computer; the ship collides with the ice body model through the driving of the towing device so as to acquire the collision data through the pressure sensor. On the premise of not using ice material, the device can carry out high-pressure loading with different ice body shapes, ice body masses, impact speeds, impact positions, ship model floating states and impact angles, the real situation of the collision between the ship and the ice can be reflected well, the cost is low, the operation is easy, and the risk is small.

Description

technical field [0001] The invention relates to a simplified calculation simulation device and simulation method for ship ice collision in water medium, belonging to the field of ships. Background technique [0002] With the rapid development of my country's economic construction, the marine economy has become a new growth point of the national economy. The development of the Arctic and the opening of the Arctic waterway not only provide new guarantees for my country's new strategy, but also shorten the shipping time. Large-scale development, sea ice disasters affecting the safety and operation of offshore structures, and the interaction between sea ice and structures have become increasingly prominent. Ships traveling in polar regions inevitably collide with ice bodies. Ship-ice collision itself is a complex nonlinear process, and research on ship-ice collision in water media adds another layer of difficulty. The current research usually considers the effect of water by imp...

There are also some scholars who consider the role of water through fluid-solid coupling. Although modern computer software and hardware are constantly upgraded, the fluid-solid coupling method uses a finite volume method to process the fluid unit, which takes a lot of calculation time, and its calculation time is about the same as that of the non-fluid-solid method. several times
