A method for measuring the bottom clearance of a ro-ro ship's vehicle running test

Abstract

The invention discloses a bottom clearance measurement method for a ro-ro marine vehicle walking test, comprising the following steps: step 1: the test vehicle stops at each bottom clearance measurement point, and the clearance value of each point under static conditions is measured; step 2: according to the static condition For the clearance value of each point measured in the test vehicle, select a number of values ​​in decreasing order to measure the bottom clearance under dynamic conditions; Step 3: Based on the values ​​determined in Step 2, arrange a number of soft metal wires at each measurement position of the test vehicle; Step 4: The test vehicle drove past the measurement point at the maximum allowable speed of the cargo compartment, and determined the range of the bottom clearance according to the bending of each wire, so as to obtain the range of the bottom clearance during movement. The present invention arranges a plurality of soft metal wires in each measurement position of the test vehicle to realize dynamic measurement, and has the advantages of simple structure, convenient operation and high measurement efficiency.

Description

technical field [0001] The invention relates to a bottom clearance measurement method, in particular to a bottom clearance measurement method for a vehicle running test on a roll-on-roll-off ship, belonging to the application field of roll-on-roll-off ships. Background technique [0002] Bottom clearance is an important technical indicator of car ro-ro ships. The test data mainly provide the basis for subsequent vehicle loading (especially small passenger cars), so that necessary measures can be taken when the bottom clearance is insufficient, and obstacles or structures that cause insufficient clearance can be checked. To ensure the safety of the vehicle when it is loaded, the traditional measurement mainly uses the test vehicle to stand still at the measurement position to measure the static clearance data of each point. However, in order to ensure the loading efficiency when the actual vehicle is loaded, the vehicle is loaded at the maximum allowable speed. , so the measu...

Problems solved by technology

Usually, the bottom clearance in motion is different from that in static state, and it is difficult to measure, so it is necessary to find a suitable and simple measurement method
