Problems solved by technology

[0003] The above two types of test methods are to lift the model to a certain height and then disengage the lifting device. The model falls into the water freely. The simple bracket can play a certain role in supporting and protecting the model. The attitude control accuracy of the two models facing the water Poor, can't achieve initial attitude adjustment, and doesn't have the ability to test the splash scale

Abstract

The embodiment of the invention discloses a model vertical water entry test device and test method. In the test device, a guide rail is vertically arranged on a throwing water pool, a pulley is vertically installed on the guide rail and used for vertically moving along the guide rail, a test piece is connected with the pulley through a plurality of connecting pieces, and the length of the connecting pieces is adjustable and used for adjusting the initial posture of the test piece; one end of the suspension wire is connected with the pulley, the other end of the suspension wire bypasses the fixed pulley to be connected with the unloading weight, the unloading weight is further connected with the lifting device, and the test piece is provided with an acceleration sensor used for measuring the acceleration after entering water and a pressure sensor used for measuring the pressure value after entering water. According to the embodiment of the invention, accurate attitude control, water entry speed control and adjustable initial attitude in the water entry process of the model can be ensured, and measurement of load, motion and splashing of the model can be realized.

Description

technical field [0001] This application relates to but not limited to the technical field of water load test, especially a model vertical water entry test device and test method. Background technique [0002] At present, for the vertical water entry test of models, especially for component-level models, the test methods used are usually free drop or simple bracket. [0003] The above two types of test methods are to lift the model to a certain height and then disengage the lifting device. The model falls into the water freely. The simple bracket can play a certain role in supporting and protecting the model. The attitude control accuracy of the two models facing the water Poor, cannot achieve initial attitude adjustment, and does not have the ability to test the splash scale. Contents of the invention [0004] In order to solve the above technical problems, the embodiment of the present invention provides a model vertical water entry test device and test method to ensure ...
