基于主动气囊的高地隙底盘调平系统设计与试验
Design and Test of High Clearance Chassis Leveling System Based on Active Airbag
摘要
Abstract
Aiming at the problems of poor stability and driving safety of the high clearance chassis when working on une-ven ground,due to the inclination of the vehicle body with the terrain,this paper designs and develops the ground clear-ance adjustment mechanism based on the four leg active air bag adjustment to adjust the chassis stability.The chassis pitch adjustment is-8.5°-8.5 °,roll adjustment is-10 °-10 °,and the maximum ground clearance of the chassis can be adjusted to 280mm.On this basis,a set of chassis leveling control system is designed.The working principle,hardware and software design and leveling control strategy of the leveling system are studied.Finally,the control response test and field test are carried out after the leveling system is installed on the prototype of high gap plant protection ma-chine.The control response test shows that the average overshoot of the active airbag is 3.36%.So as to ensure its control performance.The field test shows that the high clearance chassis with automatic leveling system can not only effectively reduce the inclination of the chassis in the field,so as to effectively improve the motion stability of the chassis,but also greatly improve the adaptability of the high clearance chassis to uneven ground.关键词
