The application provides a shearing type unlocking separation device, a dynamic test system and an unlocking force control method. The device comprises an unlocking bolt, a shearing protective sleeve and an auxiliary mechanism. The unlocking bolt comprises a first threaded section, an unlocking separation section and a second threaded section. Two weakening grooves are arranged on the unlocking separation section and extend in the same direction. The two weakening grooves are provided with through holes at the side ends close to each other. The distance between the two through holes is l. The angle between the weakening grooves and the axis of the unlocking separation section is β. The angle between the line connecting the two through holes and the radial line of the unlocking separation section is α. The two weakening grooves penetrate the unlocking separation section. The weakening grooves are filled with high-strength fillers. The shearing protective sleeve is sleeved on the unlocking separation section. The auxiliary mechanism is threadedly connected to the second threaded section. The application can realize rapid response and precise control of unlocking force, and the separation process does not produce harmful gas, and the economic efficiency and environmental benefits are good.
