计算了装载机工作装置油气减振系统的固有频率,得出了蓄能器充气压力和负载变化对系统固有频率的影响。根据系统简化的单自由度振动模型列出运动方程,编程运算得到装载机满载和空载两种状况下,路面激励频率、蓄能器充气压力和油气减振系统油液管路内径对动臂的振幅衰减效果影响。
The natural frequencies of oil-gas vibration damping system of loader working device are calculated, and the influence of accumulator inflation pressure and load on system natural frequency is obtained. According to the system simplified single-degree-of-freedom vibration model, the equations of motion are listed. The program calculates the excitation frequency of the road surface, the charge pressure of the accumulator and the diameter of the oil pipeline of the oil-gas damping system to the boom The amplitude attenuation effect.
