The invention relates to the technical field of dumper control, in particular to a dumper container descending control method and system and an operation machine.The dumper container descending control method comprises the steps that the descending height of a container is determined; when the descending height is larger than or equal to a first preset height, the lifting oil cylinder is controlled to descend at a first speed; when the descending height is smaller than the first preset height, the lifting oil cylinder is controlled to descend at a second speed so as to control the container to descend; wherein the second speed is smaller than the first speed. The lifting oil cylinder is controlled to descend at different descending speeds according to different descending heights, so that descending of the container is controlled, safe descending is achieved, impact force formed on the frame and the container when the container descends to the position of the frame is reduced, and safety is improved. And the risk of cracking of the frame or the container caused by impact on the frame due to rapid descending of the container can be avoided to a great extent.
本发明涉及自卸车控制技术领域,尤其涉及一种自卸车货箱下降控制方法、控制系统及作业机械,自卸车货箱下降控制方法包括步骤:确定所述货箱的下降高度;当所述下降高度大于或等于第一预设高度时,控制所述升降油缸以第一速度下降;当所述下降高度小于第一预设高度时,控制所述升降油缸以第二速度下降,以控制所述货箱下降;其中,所述第二速度小于所述第一速度。根据不同的下降高度控制升降油缸以不同的下降速度下降,从而控制货箱的下降,实现安全下降,减小了货箱下降至车架位置时对车架和货箱自身形成的冲击力,可以很大程度避免因为货箱快速下降冲击车架造成的车架或货箱开裂的风险。
