The invention provides an on-load solar wing ground unfolding locking
impact measurement
system and a test method thereof. The on-load solar wing ground unfolding locking
impact measurement
system comprises a six-dimensional force
measurement device, an internal force
measurement device, a six-dimensional force acquisition device and a photographing device, the solar wing connecting frame is hinged to the simulated star body, the
heavy load is installed on the connecting frame, the solar wing and the
heavy load are both hung through the hanging unfolding device, and the six-dimensional force measuring device is installed between the root hinge and the simulated star body. The six-dimensional force acquisition device, the internal force
measurement device and the photographing device are respectively used for acquiring power parameters, internal force parameters and motion parameters of unfolding
impact of the solar wing. According to the invention, a full-closed-loop ground equivalent expansion
impact measurement system with expansion locking, multi-dimensional measurement and
data processing and analysis is constructed through construction of various measurement devices, so that the deficiency of an on-
orbit expansion locking impact multi-dimensional parameter measurement scheme of a loaded large-
inertia mechanism is made up; impact motion parameters, internal force parameters, six-dimensional impact external force parameters and the like can be visually, comprehensively and quantitatively measured.
