The invention discloses a rotational locking joint, which comprises a fixed hinge joint (1), a movable hinge joint (2) and a connection release mechanism. The inner sides of the fixed hinge joint (1) is connected with the inner side of the movable hinge joint (2) through a fixed connecting axle (6), and the outer sides are connected through the connection release mechanism; a chip-type actuator spring (5) is connected with the outer side of the fixed hinge joint (1) through a lower connecting axle (7), and the other end of the chip-type actuator spring (5) is connected with the outer side of the movable hinge joint (2) through an upper connecting axle (8); when the rotational locking joint is locked, the chip-type actuator spring (5) is in a bent strained condition, and after being unfolded to a destination operating condition, the chip-type actuator spring (5) is in a stretching condition. When the rotational locking joint is locked and unfolded, the strained condition of the chip-type ...

Принадлежит:

The invention relates to a load input method based on strain feedback in a whole-satellite test, comprising the following steps: (1) the maximum value Nmax of support reaction of a binding surface of a satellite and a carry binding surface is ascertained; (2) the proportion relation of strain Epsilon generated between the satellite and the carry binding surface and binding surface support reaction N is ascertained; (3) according to the results of the steps (1) and (2), threshold value Epsilonmax of the strain Epsilon during the whole-satellite vibration test is ascertained; (4) during the whole-satellite vibration test, the load is input according to the change condition of the strain Epsilon generated between the satellite and the carry binding surface; and when the load is input, the strain Epsilon between the satellite and the carry binding surface, which is generated by the load input is ensured to be smaller than the threshold value Epsilonmax. The invention does not need complicated ...
