摘要/Abstract

摘要： 目的研究高地隙自走式喷雾机底盘悬架的减振特性,提高自走式喷雾机的作业稳定性。方法采用振动加速度传感器,采集喷雾机在不同路面下车架的振动加速度,分析车架和马达支架的振动加速度,评价气液组合悬架的减振特性。结果当喷雾机以速度3、5和8 km/h在田间行驶时,路面激励经过气液组合悬架减振后,传至车架时的振动加速度均方根值分别降低了70.43%、68.49%、66.10%,当喷雾机在以速度3、5和8 km/h在田间行驶时,路面激励经过气液组合悬架减振后,传至车架时振动加速度均方根值分别降低了69.61%、67.32%、64.74%。结论在田间路面和砂石路面上气液组合悬架均具有良好的减振特性。

Abstract:

【Objective】 To improve the operating stability of the self-propelled sprayer by studying the vibration reduction characteristics of the chassis suspension of the self-propelled sprayer with high clearance. 【Methods】 Vibration acceleration of the sprayer on different pavement was collected by using vibration acceleration sensor to analyze the vibration acceleration of the frame and motor bracket, and evaluate the vibration reduction characteristics of the gas-hydraulic combination suspension damping properties. 【Results】 When the sprayer in the speed was 3 km/h, 5 km/h, 8 km/h in the field, the road excitation after the combination of gas and liquid suspension damping, the vibration acceleration RMS value was reduced by 70.43%, 68.49% and 66.10%, respectively, and when the sprayer in the speed was 3 km/h, 5 km/h, 8 km/h in the field, the root mean square value of vibration acceleration transmitted to the vehicle frame by road excitation was reduced by 69.61%, 67.32% and 64.74%, respectively. 【Conclusion】 With the increase of the operating speed and road level of the sprayer, the gas-liquid combined suspension can ensure good vibration reduction effect.
