Device and method for vibration control and energy recovery of free-piston internal combustion generator

Abstract

The invention discloses a vibration control and energy recovery device and method of a free piston internal combustion generator. An electromagnetic energy recovery mechanism is installed between the engine cylinder head and an external mechanism at both ends of the free piston internal combustion generator; the electromagnetic energy recovery mechanism includes a dynamic The subassembly and the stator assembly matched with the mover assembly, a coil spring is arranged between the mover assembly and the stator assembly; the mover assembly is installed on the engine cylinder head and the mover assembly is provided with a permanent magnet, and the stator assembly is installed outside The mechanism and the stator assembly are equipped with coils corresponding to the permanent magnets; the coils are connected to the control system of the free-piston internal combustion generator. The control system is used to control whether the coils are energized and the magnitude of the current, and realize vibration control and energy based on the electromagnetic energy recovery mechanism. Recycle. The invention can solve the problem of excessive vibration intensity when the free-piston internal combustion generator is used as an automobile range extender, and improves the energy conversion efficiency of the system to a certain extent.

Description

technical field [0001] The invention relates to the technical field of vibration control and energy recovery, in particular to a vibration control and energy recovery device and method for a free-piston internal combustion generator. Background technique [0002] Energy application and conversion devices have always been a hot research field in scientific research. As a new type of energy conversion device, free piston internal combustion generator has the advantages of high volume power, adjustable compression ratio and convenient modular arrangement; it is very suitable for Future use of range extenders for hybrid vehicles. [0003] The free-piston internal-combustion generator is still in the stage of principle exploration. According to the current research results, when the free-piston internal-combustion generator with special structure is installed on the vehicle as a range extender, its own strong vibration and unique vibration characteristics will restrict its appli...
