Method for collecting and releasing boat hanging frame type lifeboat in state of simulating 20-degree transverse inclination of ship

The invention discloses a method for simulating folding and unfolding of a boat hanging frame type lifeboat in a 20-degree transverse inclination state of a ship, starting from the characteristics of the boat hanging frame type lifeboat, a cushion block is additionally arranged on a supporting piece of a boat hanging frame to limit the rotation angle of the boat hanging frame in the descending process, so that the 20-degree transverse inclination state of the ship is successfully simulated, and the folding and unfolding test of the lifeboat is completed. Wherein the height of the cushion block is the height difference between the supporting height of the boat hanging frame and the supporting height of an original boat hanging frame when a simulated ship is transversely inclined by 20 degrees, and the inclination angle of the upper end face of the cushion block is equal to the transverse inclination angle of the simulated ship. The method is wide in applicability, and the height of the cushion block for simula
