Abstract

The invention relates to a wave load measuring system and a measuring structure thereof. The wave load measuring system comprises a structure used for being placed in water, the structure being provided with a sealing cavity, and an avoiding hole being formed in the cavity wall of the sealing cavity; a measuring module comprising a force measuring sensor arranged in the sealing cavity; one end of the force transducer being rigidly and fixedly connected with the cavity wall of the sealing cavity; a supporting structure, arranged in the avoiding hole in a penetrating manner and being not in rigid contact with the hole wall of the avoiding hole; one end of the supporting structure being rigidly and fixedly connected with the other end of the force transducer, and the other end of the supporting structure being exposed out of the outer side of the hole wall of the sealing cavity to be fixedly connected with an environment fixing structure, so that the force transducer is fixedly connected with the environment fixing structure; and a flexible sealing structure, arranged in the avoiding hole so as to seal a gap between the hole wall of the avoiding hole and the supporting structure. According to the measurement module of the wave load measurement system, the influence of a traditional connecting piece on the measurement precision and stability is avoided, and the measurement precision and stability can be effectively improved.

Description

technical field [0001] The invention relates to the field of wave load research, in particular to a wave load measurement system and a measurement module thereof. Background technique [0002] Wave loads involve important safety protection issues in marine engineering, so there are a lot of research in this field. Carrying out model experiments in the laboratory is an important means to study this problem. To accurately measure wave loads, a reliable wave load measurement system is required. Generally speaking, the direction of wave load can be described by six degrees of freedom, which are flow direction, lateral direction, vertical direction, flow direction rotation, lateral rotation and vertical rotation. The corresponding six loads are called flow force, lateral force, vertical force, roll moment, pitch moment and yaw moment. Traditionally, a wave load measurement system includes a structure placed in water to withstand wave loads, and a load cell that is rigidly and ...
