Abstract

The invention relates to a cabin-level axial double-table synchronous vibration test system, and belongs to test systems. The test system comprises two vibrating tables, high-frequency hydraulic bulbs, a tail tool and a head tool, the two vibrating tables are arranged at the two ends of the whole test system respectively, the output end of each vibrating table is fixedly connected with one corresponding high-frequency hydraulic bulb, the vibrating table arranged at the front end is fixedly connected with the head tool via the high-frequency hydraulic bulb, the vibrating table arranged at the rear end is fixedly connected with the tail tool via the high-frequency hydraulic bulb, and a tested piece is mounted between the head tool and the tail tool. The test system has the following advantages that two vibrating tables are included, and used to vibrate and load the test piece, a cantilever effect is avoided, the working environment of the test piece can be reflected closer to the fact when loading is carried at the two ends simultaneously, the real degree of ground test simulation is improved, the safety and reliability are higher, and the application range is wider.

Description

technical field [0001] The invention belongs to a test system, in particular to a cabin-level axial double-stage synchronous vibration test system. Background technique [0002] With the continuous development of science and technology, the carrying and carrying capacity of spacecraft is gradually improved, which will inevitably increase the weight and size of the whole and parts. Using traditional test methods will bring the risk of over-testing. In the past, most of the axial tests were loaded by a single machine. The size of the test piece continued to increase, and the center of mass of the test piece would become higher during the test. The thrust requirements for the shaking table continued to increase, and the test preparation period also became longer. Contents of the invention [0003] The object of the present invention is to provide a cabin-level axial double-stage synchronous vibration test system for the defects of the prior art. [0004] In order to achieve ...
