A forced vibration directly driving generation system with an accelerating spring uses linear motion of a reciprocating engine piston (1) to drive a coil (7) or a magnet (9) and generate electricity. A spiral spring (8) of a main vibration system including the piston (1), the generating coil (7), the spiral spring (8) and a connector (2) is connected with the accelerating spring (13) with high elastic coefficient at bottom dead point of the piston, so they can form a compression spring with variable elastic coefficient near the bottom dead point. A spiral spring (15) is placed between a balancing spring and the main vibration system, so theycan form a spring with variable elastic coefficient near the top dead point. After the accelerating springs are connected with the main vibration system, their vibration frequency is consistent with the main vibration frequency, and their phases are harmonious, so the vibration and noise can be reduced. |
