The embodiment of the invention provides a load moment determination method for engineering machinery, a processor, a device and a storage medium, and belongs to the technical field of engineering machinery, the method comprises the following steps: when a hydraulic oil cylinder drives a cargo boom to perform amplitude variation, obtaining the oil cylinder force of the hydraulic oil cylinder; obtaining the length of a hydraulic oil cylinder and the variable-amplitude inclination angle of the cargo boom Determining an oil cylinder force arm according to the length of the hydraulic oil cylinder and the jib luffing dip angle; obtaining the total torque of the engineering machinery according to the oil cylinder force and the oil cylinder force arm; and carrying out difference calculation on the total moment and the mechanism gravitational moment to obtain the load moment of the engineering machinery. The oil cylinder force arm is determined according to the length of the hydraulic oil cylinder and the derricking dip angle of the cargo boom, the total moment of the engineering machinery is determined according to the oil cylinder force of the hydraulic oil cylinder and the oil cylinder force arm, the load moment can be determined based on the total moment and the mechanism gravitational moment, and the load moment measurement process does not need human participation and is not affected by external factors. Therefore, the measurement accuracy of the load moment can be effectively improved.

    本发明实施例提供一种用于工程机械的起重力矩确定方法、处理器、装置及存储介质,属于工程机械技术领域,该方法包括:在液压油缸带动起重臂进行变幅时,获取液压油缸的油缸力;获取液压油缸长度和起重臂变幅倾角;根据液压油缸长度和起重臂变幅倾角,确定油缸力臂;根据油缸力和油缸力臂,得到工程机械的总力矩;对总力矩和机构重力矩进行差值计算,得到工程机械的起重力矩。本发明根据液压油缸长度和起重臂变幅倾角确定油缸力臂,并根据液压油缸的油缸力和油缸力臂确定工程机械的总力矩,基于总力矩和机构重力矩即可确定起重力矩,该起重力矩测量过程无需人为参与,也不会受到外部因素的影响,因而能够有效提高起重力矩的测量准确度。
