Abstract

The invention discloses a method for improving the performance of a differential steering system of tracked vehicle hydraulic machinery, aiming at multiple optimal parameters such as planet row characteristic parameters, hydraulic closed loop system parameters, motor post-transmission ratio, dead axle gear transmission ratio and the like of the differential steering system of hydraulic machinery, multiple evaluation sub-objects such as the steering dynamic property (dynamic factor), the steering flexibility (steering radius), the steering rapidity (steering time) and the like of the tracked vehicle are evaluated comprehensively; the mutual coupling relationships between the optimal parameters are processed by using a layer partitioning problem space method, so that each optimal parameter is enabled to correspond to one layer problem space, thereby the flexibility of optimal parameter selection is increased, the analysis calculation on an ineffective parameter combined scheme during the optimization process is avoided, and the parameter optimization efficiency is improved.

Description

technical field [0001] The invention relates to the field of hydromechanical differential steering system and its optimization for crawler vehicles. Background technique [0002] The steering system of tracked vehicles has generally experienced steering clutch-brake, mechanical dual power flow steering system and hydromechanical differential steering system. The hydromechanical differential steering system is a new dual power flow steering system combined with hydraulic transmission, mechanical transmission and planetary gear transmission (such as figure 1 ). Compared with the traditional steering system, it has the advantages of excellent dynamic characteristics, stepless steering of tracked vehicles, high operating efficiency, light operation, low labor intensity, good direct driving stability, and precise steering trajectory. [0003] In order to improve the performance of the hydromechanical differential steering system of tracked vehicles, engineering usually adopts t...
