Parameter Identification of Hydraulic System of Armored Engineering Vehicle

In hydraulic system, parameters are complex and difficult to calculate accurately and quantitatively. The key parameters usually rely on a large number of repeated trials. In order to realize parameter identification of a certain type of armored engineering vehicle, a multigroup hybrid algorithm is proposed in this paper based on the analysis of traditional mechanical arm dynamics and hydraulic model. A reasonable mechanical hydraulic model joint parameter identification is achieved. Experiments are carried out on a vehicle experiment platform with a joint sensor acquisition system, and the rationality of the model is evaluated by a self-consistent system. Experimental results show that the method is feasible and has better identification effects.
