Description

Technical Field

[0001] This utility model relates to a multi-factor coupling test platform for marine materials, belonging to the field of marine new material testing technology. Background Technology

[0002] Marine new materials refer to various special materials used in marine development under high humidity, high salinity, and high pressure environments, and are the material basis of marine engineering equipment. Strengthening research on marine new materials is beneficial to marine exploration and the development and utilization of marine resources.

[0003] Currently, single-factor cyclic aging tests are commonly used to evaluate materials or components of marine engineering equipment. These tests are often limited to a single environmental factor, but the actual marine environment is highly complex and is the result of the combined effects of multiple environmental stress factors. There are significant differences between existing single-factor evaluation methods and the actual marine environment, making it difficult to accurately reproduce the impact of the real marine environment on materials. Traditional evaluation methods have obvious limitations in simulating the real marine environment and cannot ensure the accuracy and reliability of the evaluation results. Utility Model Content

[0005] The technical solution of this utility model is as follows: A multi-factor coupling test platform for marine materials includes a three-phase main power supply, and also includes: The protective module is divided into an experimental chamber and a control chamber by a partition; The environmental simulation module includes a first blower and a second blower located on both sides of the experimental chamber, and a third blower and a fourth blower located in the control chamber. The air inlet of the third blower is equipped with a salt spray filter. The aging module includes a power frequency transformer system and a SCOTT transformer. Both the experimental chamber and the control chamber are equipped with power frequency transformer systems, which include step-up transformers, voltage regulators, and control cabinets. The primary side of the SCOTT transformer is connected to the three-phase main power supply, and its two output terminals on the secondary side are connected to the experimental chamber and the control chamber respectively to provide power to the power frequency transformer system.

[0009] This utility model has the following beneficial effects: 1. Set up experimental and control chambers, along with aging and online monitoring modules, to provide accelerated aging tests and evaluation services for marine engineering equipment materials that closely resemble the real service environment. The aging module accelerates the aging rate of marine engineering equipment materials, and the online monitoring equipment continuously monitors multiple characteristic values ​​of the samples during the aging process. Multi-factor coupling analysis is conducted to analyze the weather resistance and aging law of marine engineering equipment materials, further assisting in the structural design, material selection and process optimization of marine engineering equipment, and providing reliable experimental data to improve the service life and reliability of marine engineering equipment, reduce operation and maintenance costs and safety risks. 2.
