Abstract

A physical parameter adjusting device of flexible members in the technical field of measuring instruments includes: a base, a straight track, a hoisting sliding block, an extension sliding block and agrating displacement sensor, wherein the straight track is fixedly connected with the base, the hoisting sliding block and the extension sliding block are arranged on the straight track, and the grating displacement sensor is fixed on the side of the straight track. The device can fix the flexible members on the sliding blocks and then adjust a flexible member model that is dozens of meters longby using a motor to drive the sliding blocks to move on the straight track, and is high in automation degree and accurate in measurement.

Description

Technical field [0001] The invention relates to a device in the technical field of measurement, in particular to a device for adjusting the physical parameters of a flexible component. Background technique [0002] Both the mooring system and the riser system are important subsystems of deep-sea platforms such as semi-submersible platforms. They are generally composed of flexible components such as anchor chains, mooring cables, risers, etc. The length, diameter, and unit are required for the tank model test. Various physical parameters such as length, weight, and axial stiffness are accurately simulated to ensure that the mechanics is similar to the actual structure and the reliability of the model test. At present, there is no facility for simulating the axial stiffness of flexible components such as anchor chains in China. When doing this kind of test, a set of simple vertical adjustment devices should be temporarily installed according to the specific dimensions of the flexi...
