摘要:【中文】本发明属于全断面岩石掘进机掘进技术领域,提出了一种掘进机主驱动系统质量协调减振装置的设计方法。本发明利用左上及右上护盾作为质量协调减振装置的质量块,设计一种能适应于实际掘进过程中主机多方向耦合振动的振动传导结构,梳理系统的轴向及倾覆振动,将其整合传导至减振质量块的轴向平移振动,利用质量块的共振最大程度的吸收系统振动能量,从而延长掘进机主机系统寿命,减轻掘进机振动,降低噪音,缩短掘进机研制周期,提高掘进效率,降低了工程的经济损失。 【EN】The invention belongs to the technical field of full-face rock tunneling machine tunneling, and provides a design method of a quality coordination vibration damper of a main driving system of a tunneling machine. The invention utilizes the upper left shield and the upper right shield as the mass blocks of the mass coordination vibration damper, designs a vibration conduction structure which can adapt to multi-direction coupling vibration of the main machine in the actual tunneling process, combs the axial and overturning vibration of the system, integrates and conducts the axial and overturning vibration to the vibration damping mass block, and absorbs the vibration energy of the system to the maximum extent by utilizing the resonance of the mass blocks, thereby prolonging the service life of the main machine system of the tunneling machine, reducing the vibration of the tunneling machine, reducing the noise, shortening the development period of the tunneling machine, improving the tunneling efficiency and reducing the economic loss of the engineering.
