The invention provides an ultra-static vacuum testing device and method in order to solve the technical problems that the spacecraft ground vacuum test result is inaccurate and even test cannot be performed due to vibration and jitter of a vacuum test device. According to the invention, a vacuum tank and a test vacuum tank are separated and are connected through a corrugated pipe, so that a dry pump, a molecular pump and a cryogenic pump are prevented from being directly connected to the test vacuum tank, and the vibration influence on the test vacuum tank in the operation process is avoided;through the support of an air cylinder of a first air floating platform, the test vacuum tank is enabled to be in an air floating state, and the vibration influence of the outside on the test vacuum tank is isolated; through the support of an air cylinder of a second air floating platform, an object carrying platform is enabled to be in an air floating state, so that a test product placed on the object carrying platform is in an air floating state, and the vibration influence of the outside on the test product is isolated.
为了解决真空测试装置的振动和抖动导致航天器地面真空测试结果不准确，甚至无法测试的技术问题，本发明提供了一种超静真空测试装置及方法。本发明将真空罐和测试真空罐分离，二者之间采用波纹管连接，避免了干泵、分子泵、低温泵直接连接在测试真空罐上，在运转过程中对测试真空罐的振动影响；通过第一气浮平台的气缸的支撑，使测试真空罐处于气浮状态，隔绝了外界对测试真空罐的振动影响；通过第二气浮平台的气缸的支撑，使载物平台处于气浮状态，进而使得置于载物平台上的试验产品处于气浮状态，隔绝了外界对试验产品的振动影响。
