The invention discloses a vibration-acceleration coupling environment test system used for a spacecraft dynamic test. The system comprises an acceleration environment test system and a vibration environment test system. The acceleration environment test system is used for providing constant linear acceleration environment stress through jib rotation and mainly comprises a base, a motor, a transmission system, a speed measurement device, a working jib, a current collecting ring and an electronic control system. The vibration environment test system is used for providing vibration excitation and mainly comprises an electromagnetic vibration table body, a forced air cooling system and an image photographing system. The electromagnetic vibration table body, the forced air cooling system and the image photographing system are fixed on a centrifuge jib through bolts. The environment test system has the advantages of being simple in structure and easy to control and can be used for providing the vibration-acceleration coupling dynamic test for the spaceflight product.
Description
technical field [0001] The invention belongs to the technical field of spacecraft dynamics test, in particular, the invention relates to a vibration-acceleration coupled environmental test equipment. Background technique [0002] In the national defense industry, aerospace products generally work in a coupled dynamic environment where vibration and linear acceleration act simultaneously, such as when a spacecraft is in the launch phase, when an aircraft is climbing, diving, and circling, when a strategic missile is in the active section and through the reentry section At the same time, its equipment and devices are subject to the coupling effect of acceleration overload and engine vibration. However, in the current mechanical environment test, due to the lack of coupling test equipment, the vibration test and the centrifugal test are generally carried out separately in time, and the product's tolerance to vibration or linear acceleration single stress is assessed on the vibr...
