    摘要:

    針對拖拉機減振性能差的問題，以定位閥輸入電壓與磁流變減振器勵磁電流作為半主動懸架特性參數(shù)，進行了參數(shù)匹配臺架試驗。基于匹配試驗結(jié)果，提出頻域快速控制策略，采用LabView作為軟件開發(fā)平臺，以PCI6024E型數(shù)據(jù)采集卡為核心設(shè)計了半主動懸架控制系統(tǒng)，進行了試驗驗證。結(jié)果表明，定位閥輸入電壓與磁流變減振器勵磁電流的合理匹配，可明顯衰減懸架動態(tài)特性響應(yīng)；所設(shè)計的半主動懸架控制系統(tǒng)能有效抑制簧載質(zhì)量的垂向振動，改善拖拉機減振性能。

    Abstract:

    Aiming to the problem of poor tractor performance, the matching bench test of positioning valve input voltage and magnetorheological damper excitation current was done. Based on the matching test, a frequency adjust based control strategy was proposed. Using LabView as the software development platform and PCI6024E DAQ as the core, the semi-active suspension control system was established and validated. The results showed that the reasonable match of positioning valve input voltage and magnetorheological damper excitation current could significantly attenuate the suspension dynamic characteristic response. The semi-active suspension control system could effectively suppress the sprung mass vertical vibration, and improve the tractor performance. 
