摘  要：
轴向柱塞泵广泛应用于农机液压系统中,但工作过程中受到机械振动和液压冲击,容易诱发故障,严重时导致设备损坏。本文针对以上因素开展柱塞泵的运动学和动力学分析,期望通过对柱塞泵自由度、运动和受力规律的推导计算及仿真分析来探索柱塞泵产生机械噪声的主要原因。通过建立起相应的数学模型,运用Pro/E软件对柱塞泵进行几何建模,利用接口程序Mechanism/Pro将柱塞泵几何模型转换到多体动力学软件ADAMS中,根据柱塞泵的运动规律添加复杂约束和力,进行运动学和动力学仿真分析,得到主要零部件不同工况下的位移、速度、加速度和受力曲线。将理论推导和仿真分析对比,从机械角度分析噪声的原因是柱塞所受惯性力的急剧变化和柱塞滑靴组件连接点的压力超调大于额定压力的5%。

摘  要：
Axial piston pump is widely used in agricultural machinery hydraulic system, but it is subject to mechanical vibration and hydraulic shock during the working process, which is easy to induce failure and equipment damage in serious cases. In this paper, the kinematics and dynamics analysis of the plunger pump are carried out for the above factors. It is expected that the main reason for the mechanical noise generated by the plunger pump is explored by the calculation and simulation analysis of the plunger pump's degree of freedom, motion and force. By establishing the corresponding mathematical model, the piston pump is geometrically modeled by Pro/E software, and the plunger pump geometry model is converted into the multi-body dynamics software ADAMS by the interface program Mechanism/Pro, according to the movement of the plunger pump. Regularly add complex constraints and forces, perform kinematics and dynamics simulation analysis, and obtain the displacement, velocity, acceleration and force curves of the main components under different working conditions. Comparing the theoretical derivation with the simulation analysis, the reason for analyzing the noise from the mechanical point of view is the rapid change in inertial force experienced by the plunger and the pressure overshoot of the connection point of the plunger shoe assembly is greater than 5% of the rated pressure.
