Research on Hydraulic Breaker with Self-Adaptive Buffer

在分析国内外液压振动破碎锤缓冲机构的基础上,提出一种新型自适应缓冲机构的工作原理,并建立了液压冲击器缓冲机构的振动力学模型,提出了实现液压振动破碎锤缓冲机构自适应控制的微机控制系统。建立了缓冲机构阻尼微机控制系统的Simulink仿真模型,运用可视化的仿真软件Simulink对该系统的动态响应特性进行了仿真分析,论证了缓冲机构的微机控制系统能够根据加速度传感器的采样调节系统的阻尼,实时地控制主机的振动状态,为智能型液压振动破碎锤研究与开发提供了理论依据。

After analyzing the buffer of hydraulicbreaker at home and abroad, the paper brings forward aworking principle of new self--adaptive buffer, establish-es a vibration mechanics model of the buffer, and pre-sents a control system of the self--adaptive buffer of thehydraulic breaker which is controlled by single--chipcomputer. Au the same time, a Simulink model of the mi-crocomputer control system of the self--adaptive buffer iseslablised,and computer simulation on dynamic character-istics of the system is performed it is proven the micro-computer control system can adjust the damping by de-tecting acceleration sensor for controlling the workingstate of the hydraulic breaker. The work provides a theo-retical basis and technical guidance for the development ofa intelligent hydraulic breaker.
