The invention discloses a gravity unloading device of an asymmetric side plate two-dimensional unfolding solar wing and a counterweight calculation method of the gravity unloading device. Side plate counterweight blocks in the device are connected to lifting ropes between two end pulleys and corresponding side plates in a one-to-one correspondence mode, and sine counterweight blocks are connected with an overturning beam through arm rods of the sine counterweight blocks; the sum of gravitational torques of the lifting rope, the two side plates, the two side plate balancing weights and the sine balance weight acting on the overturning beam rotating shaft is zero, so that the gravity of the asymmetric side plate two-dimensional unfolding solar wing is completely unloaded; according to the method, a lower side plate balancing weight, an upper side plate balancing weight and a sine balance weight are calculated and configured according to a sine function expression of the sum T of gravitational torques acting on a turnover beam rotating shaft, so that the sum T of the gravitational torques acting on the turnover beam rotating shaft in the unfolding process is equal to zero. The problem that in the unfolding process of the two-dimensional unfolding solar wing, the gravity cannot be completely unloaded due to the fact that the mass centers and the weights of the upper side plate and the lower side plate are asymmetric can be solved. The problem that in the unfolding process of the two-dimensional unfolding solar wing, gravity cannot be completely unloaded due to the fact that the mass centers and the weights of upper and lower side plates are asymmetric can be solved.
