Multifunctional falling body slamming test device and test method

Abstract

The invention provides a multifunctional falling body slamming test device and a multifunctional falling body slamming test method, and belongs to the field of falling body slamming tests. The problems of a large-scale model test in a falling body slamming test, inclined displacement water entry of a large-scale model and three-dimensional attitude control of the model are solved. The device comprises a positioning base, an external supporting frame, a wedge slamming model, a displacement adjusting device, a guide rail assembly, a posture adjusting clamp, a model hoisting and releasing device and an operation platform, the model hoisting and releasing device is used for hoisting and releasing the posture adjusting clamp, and the posture adjusting clamp is used for adjusting the inclination angle of the wedge slamming model. The rotation angle of the guide rail assembly is adjusted through the displacement adjusting device, and then the inclination displacement of the posture adjusting clamp and the wedge-shaped body slamming model is adjusted to enter water. The displacement and speed direction of the model entering water are adjusted through the displacement adjusting device, the three-dimensional posture of the model is adjusted through the clamp, the structure is simple and reliable, operation is convenient, and accurate control over the posture and speed of the model is achieved.

Description

technical field [0001] The invention belongs to the field of falling body slamming test, in particular to a multifunctional falling body slamming test device and a test method. Background technique [0002] In the process of ship sailing in waves, slamming load, as an important part of environmental load, has an important impact on the ship's structural strength and navigation safety. At present, the related research methods of slamming load include theoretical analysis, numerical simulation model test, etc. As far as the current research situation is concerned, the model test of the local structure is still the most accurate and intuitive scientific research method to study the slamming load. In the process of ship slamming, there are two situations: vertical water slamming and inclined water slamming, which is extremely obvious in the seakeeping experiment of the whole ship model and the observation of real ship motion. In the falling body slamming test, it is required th...
