Description

technical field [0001] The invention belongs to the technical field of dynamic measurement of steel structures, and specifically refers to a dynamic deformation measurement device for ship steel structures and a method for using the same. Background technique [0002] There are frames, trusses and other structures formed by a large number of steel members on the ship. Since the ship is moving, whether these steel structures are fixed or moving relative to the hull, they are essentially moving steel structures, and moving The design requirements of the steel structure and the static steel structure are different, so the verification methods are also different; therefore, it is necessary to simulate the operation and turbulence of the ship on the dynamic simulation device, and test the various aspects of the structure under this working condition. deformation of the structure.

AI Technical Summary

Problems solved by technology

[0003] The dynamic deformation of the steel structure is often reflected by the distance change between two points and the angular deflection of the connecting line. Due to the difference in point selection, after the measuring device is fixed on the two points, the measuring instrument needs to be reset to zero first. (that is, the positive direction of the measuring device coincides with the direction of the line connecting the two points), but the zeroing process of the general measuring device is more complicated and requires repeated adjustments; and because the simulation device is large in size and high in cost, the steel structure During the dynamic simulation of the system, it will not only measure the relative position changes of two points, but set several groups (two points in each group), and analyze the dynamic deformation of the entire structure through the data of multiple groups of anchor points, which leads to The preparation work before measurement will be extremely cumbersome
