Experiment device for ship launching through longitudinal oil-applied slideway

Abstract

The invention discloses an experiment device for ship launching through a longitudinal oil-applied slideway. The experiment device comprises a platform. One end of the platform is hinged with a bracket, and the other end is mounted on a liftable device. A slideway is mounted on the platform. A ship model is placed on the slideway. One side of the platform is provided with a water trough. A high-resolution camera is arranged outside the water trough. The ship model is provided with a strain sensor. The strain sensor is electrically connected with a charge amplifier, a multichannel signal acquisition instrument and a computer. The computer is connected with the high-resolution camera. According to the experiment device for ship launching through the longitudinal oil-applied slideway, through the scale-reduced proportional model, a ship launching influence parameter is quantified, and ship launching is visually demonstrated. Furthermore the experiment device can realize quantified analysis for each influence parameter. After scale-reducing computing, reference data are supplied for safe launching of an actual ship.

Description

Technical field [0001] The invention relates to an experimental device for launching a ship's longitudinal oil chute, and belongs to the field of teaching experimental instruments. Background technique [0002] The sloping slipway is supplemented with a longitudinal oil slide to make the ship glide along the longitudinal direction. It can be used for ships of various types and different launch weights. It has a wide range of applications and is currently one of the commonly used launch methods at home and abroad. [0003] However, due to the expensive ship construction and long construction period, the current teaching of ship launching only stays at the stage of theoretical teaching and audio-visual teaching. Teachers cannot demonstrate the launching process and explore the troubleshooting methods on the spot, and can not let students intuitively see the ship launching process. And the damage to the ship caused by the failure of launching. The current construction experience show...

Problems solved by technology

[0003] However, due to the expensive ship construction and long construction period, the current ship launching teaching only stays at the stage of theoretical teaching and audio-visual videos. Teachers cannot demonstrate the launching process and explore the troubleshooting methods of launching on the spot, and students cannot intuitively see the ship launching process. and the damage to the ship caused by launching into the water due to failure

The current construction experience shows that the causes of ship launching failures mainly fall into the following three categories: 1) the ship cannot slide down or stops midway; 2) the ship's stern falls; 3) the ship's bow falls, students cannot observe these three experiments very intuitively
