【 摘 要 】

The structural characteristics of our country's corn harvester are narrow-track, high centroid and existence of eccentric distance, so rollover accident is easily to occur when going up and down the hills mountainous and hilly regions for complex terrain. In the previous paper, we introduced the Hydro-Pneumatic Suspension to prevent the roller of the harvester, and took ADAMS simulation on the left and right roller, and obtained that the use of Hydro-Pneumatic Suspension can improve the side angle of the harvester for 5°. At the same time, we continue to use the Hydro-Pneumatic Suspension as the key part of the anti-roller system of the harvester. In the uphill and downhill case of the harvester, we respectively simulated the anti-roller performance on the traditional harvester and the harvester installing the Hydro-Pneumatic Suspension. Finally, we got that the anti-roller angle of the harvester installed Hydro-Pneumatic Suspension is obviously higher than the traditional harvester, which indicates that the anti-rollover performance of the harvester installed Hydro-Pneumatic Suspension is better than the traditional harvester. The data obtained from this experiment will provide technical support for the following structure optimization of the harvester.
