The invention aims to provide an optimization method for a loading operation motion trail of a hydraulic loader. The method comprises the steps that A, a loader shoveling work mechanism model is constructed, and a dynamical model is established to obtain a bucket motion function and a hydraulic cylinder motion function; B, a material pile consistent with the actual condition is constructed and imported into a loader shoveling work mechanism dynamical model, and a bucket motion function in the model is made to be consistent with the bucket motion function obtained in the step A; C, process simulation of loading operation of a bucket model is performed according to a preset typical condition to obtain a bucket motion trail and shoveling resistance in the whole material shoveling process of the bucket model, the bucket motion trail is optimized, and a motion curve obtained after optimization is synthesized; and D, the motion curve is imported into multi-body dynamical software to obtain a new hydraulic cylinder motion function, and therefore optimization of the loading operation motion trail of the hydraulic loader is realized. The method overcomes the defects of low precision and high cost in the prior art and has the advantages of high precision and low cost.
Description
technical field [0001] The invention relates to the field of engineering machinery simulation, in particular to a method for optimizing the motion track of a hydraulic loader for loading operations. Background technique [0002] The construction machinery industry is a high-energy-consuming industry, and the scale and output value of my country's construction machinery industry has leapt to the first place in the world. In the whole operation cycle of the loader, the energy consumed by the material shoveling work cycle accounts for the largest proportion of the overall energy consumption of the loader, and the operation resistance is also a direct factor affecting the loading capacity and efficiency of the loader. At the same time, the working resistance reflects the structural strength of the loader's working device, and is directly related to whether the working load of each working device is true or not. [0003] At present, the methods of working resistance such as inse...
