双钢轮振动压路机振动功率研究

Investigation into Vibration Power of Double- Drum Vibratory Roller

理论分析、ADAMS仿真分析和试验结果对比表明,双钢轮振动压路机前后振动轮单振时振动系统负荷波动始终存在,振动液压系统实际功率消耗大于理论计算功耗。前后振动轮双振时,改变前后轮振动相位差可以使振动系统负荷波动发生改变,降低振动系统实际功率消耗。当前后轮振动相位差为180°时,前后轮振动系统负荷波动相互抵消,振动液压系统实际消耗功率最小,应尽可能使双钢轮振动压路机在该状态下工作。

The theoretical analysis , ADAMS simulation and test results show that there is always vibrating system load oscillation when the front or rear wheel vibrates separately , so the vibration system power consumption is greater than the theoretical value .By changing the phase difference between the front and rear vibration wheel , the vibration system load oscillation can be changed and the actual power consumption can be reduced when the front and rear vibration wheel vibrate together .The actual vibration power consumption reaches its minimum value when the phase difference is 180＆#176;due to the mutual cancellation of the front and rear wheel vibration load oscillation.As a result, the double-drum vibratory roller should work in this state as much as possible .
