Description

technical field [0001] The invention relates to measurement technology, in particular to a distributed networked full physical ground simulation device and method for an aircraft. Background technique [0002] Once the space vehicle is launched, it will be difficult to maintain, and its special operating environment makes the ground simulation test particularly important. At present, the space vehicle ground simulation is mainly divided into three categories: (1) mathematical / computer software simulation; (2) semi-physical simulation; (3) Full physical simulation. One of the most effective and convincing is the full physical simulation test. The three-axis air bearing table in its core equipment room relies on the air film formed between the air bearing and the bearing seat by compressed air to make the simulated table body float, so as to realize the relative motion condition of approximately frictionless, so as to simulate space vehicles such as satellites A mechanical e...
