| 中文摘要: |
| 为研究由实际制造引起的机械系统差异对系统自同步能力的影响，提出了以双马达无同步齿轮液压振动锤为研究对象，结合流体力学、机械振动、机械系统动力学和机电液耦合动力学理论，建立了新型无同步齿轮的液压振动锤模型。运用matlab/simulink计算机数值仿真对该模型进行研究，分析了机械系统的差异对系统自同步振动的影响规律。仿真结果表明，由制造误差造成的偏心块质量差异和回转轴系的摩擦系数差异，差异在一定范围内液压振动锤可以实现同步振动。当超过这一范围时，系统同步性消失，无法实现同步振动。试验结果表明，建模仿真正确反映了机械系统差异对系统自同步能力影响的规律。 |

| In order to study the influence of the difference of mechanical system on the self-synchronization ability of the system caused by the actual manufacturing, a dual-motor non-synchronized gear hydraulic vibratory hammer was proposed as the research object. Based on the theory of fluid mechanics, mechanical vibration, mechanical system dynamics and electromechanical-fluid coupling dynamics, a new type of hydraulic hammer without synchronization gear model was established. By using matlab/simulink to simulate the model, the influence of mechanical system on self-synchronizing vibration was analyzed. The simulation results show that the difference caused by the manufacturing error in the mass of the eccentric block and the friction coefficient of the rotary shaft system, and the hydraulic vibratory hammer can realize the synchronous vibration after a certain time oscillation when the difference within limits. When it exceeds this range, the system synchronization disappear, and unable to achieve synchronous vibration. The experimental results show that the modeling and simulation correctly reflect the relationship between the difference of the mechanical system and the self-synchronization ability of the system. |
