Electric Loader Steering System Electro-hydraulic Flow Matching Control Strategy
摘要
Abstract
Aiming at the problem of serious throttling loss under the single-action condition of the priority flow amplification steering system of electric loader,an energy-saving control strategy with adaptive matching of electro-hydraulic flow is proposed.Firstly,the working principle of priority flow amplification steering system is introduced.Secondly,the energy loss model of the steering system is established.Then,the electro-hydraulic flow matching control strategy of the steering system is proposed to match the output flow of the hydraulic pump with the demand flow of the steering system,and a nonlinear mapping compensation model for the flow of the hydraulic pump is constructed to improve the flow control accuracy.Finally,the system simulation model is built by AMESim software,and the simulation analysis is compared with the original system.Results show that the flow loss of the improved system is reduced by 62.68％and the energy loss is reduced by 65.26％,and the energy-saving effect is remarkable,which lays a foundation for the promotion and application of electric loader.关键词
