Description

technical field [0001] The invention belongs to the technical field of environmental adaptability and reliability test, and specifically relates to an environment simulation test system realizing multi-physics field coupling, which simulates rainfall, temperature, humidity, wind force, light, vibration, etc. of various engineering buildings in the natural environment. Background technique [0002] As the requirements for model test volume and accuracy are getting higher and higher, there is an urgent need for a test system that can simulate various physical fields such as different temperatures, different humidity, wind, ultraviolet rays, and rainfall in nature and their couplings. However, the current experimental devices that can simulate the natural environment are relatively simple, and it has not fully considered that it is not a single physical field that affects the project to be studied in nature, but the coupling of multiple physical fields.

However, the current experimental devices that can simulate the natural environment are relatively simple, and it has not fully considered that in nature, it is not a single physical field that affects the project to be studied, but the coupling of multiple physical fields

[0003] The main work undertaken by the environmental simulation test system is various model tests. The existing equipment and inventions often only consider the simulation of various environmental fields, and do not take into account the difficulty of monitoring model tests in the environmental simulation test system. Engineering models of various geological forms provide convenient construction methods, but also bring great difficulties to the monitoring of various model tests
