提出了一种基于压力反馈的新型液压冲击器控制方案。该方案通过调整溢流阀的设定压力来控制冲击器的行程,从而具有无级调频调能的特性.建立了该冲击器的数学模型和仿真模型,并在仿真模型中充分考虑了溢流阀特性、高压油管及进出油容腔对冲击器性能的影响,系统地研究了主要工作参数对其工作性能的影响,从中获得了一些有关该液压冲击器的运动规律,为设计制造新一代液压冲击器产品提供理论依据。 A new hydraulic impactor control scheme based on pressure feedback is proposed. The program controls the stroke of the impactor by adjusting the set pressure of the relief valve, so it has the characteristics of stepless frequency modulation and adjustment.The mathematic model and the simulation model of the impactor are established, and the overflow model is fully considered in the simulation model Valve characteristics, high-pressure tubing and access to the oil chamber impact on the performance of the impact of the main operating parameters of the system to study the impact on its performance, obtained some of the movement of the hydraulic impactor for the design and manufacture of a new generation of hydraulic Impactor products provide the theoretical basis.
