Title:
FOUR-ENVIRONMENTAL-FACTORS COMBINED VIBRATION TESTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/087744
Kind Code:
A1
Abstract:
A four-environmental-factors combined vibration testing system, relating to the technical field of environmental simulation testing apparatuses. The four-environmental-factors combined vibration testing system comprises a vibration table body (1), a test chamber (2), balance assemblies (4) and positioning assemblies (5). A test table assembly (3) is provided in the test chamber (2); at least two balance assemblies (4) are provided, and are spaced apart from each other in the circumferential direction of the test table assembly (3), and the balance assemblies (4) are connected between the test table assembly (3) and the test chamber (2), so that the test table assembly (3) is in a state of balance under a testing pressure; and at least two positioning assemblies (5) are provided, and are spaced apart from each other between the test table assembly (3) and the test chamber (2) in the circumferential direction of the test table assembly (3), and the positioning assemblies (5) are suitable for applying an acting force, which is opposite an elastic force, to the test table assembly (3), so that the test table assembly (3) is in a state of balance under atmospheric pressure. The problem of an air-cooled vibration table in the prior art not being capable of normally operating due to the imbalance of a working table surface under a testing air pressure can be solved, so that the four-environmental-factors combined vibration system can perform a normal testing operation in a low-pressure or high-pressure environment.
