車載小泵
英文
portable pump-
Dynamic characteristics of a7v225 braking variable pump, accumulators storage and outlet property, braking and auxiliary driving property of hydraulic systenu load ' s simulation of auxiliary driving and so on have been analyzed in the article. hydraulic storage braking and auxiliary soft starting of down belt conveyor have been simulated in laboratory, at the same time, have testified that this energy saving hydraulic system is available
通過實驗,並應用了小波分析去噪等數據處理手段,文中對a7v225剎車變量泵的動態特性、蓄能器的儲能和放能特性、液壓系統的制動和輔助驅動特性及輔助驅動時負載的模擬等,分別進行了分析。In the second optimization model, the first mode frequency is decreased to let it below the frequency of brunt load and cut down greatly the structural mass
在第二個優化模型中,考慮減小泵車的一階頻率,盡量低於油缸沖擊載荷的頻率,同時可使結構質量有較大幅度下降。Meanwhile, there is a kind of constraint, only the frequency constraint. the optimization design is computed to increase the first mode frequency. as the results, the first mode frequency is increased and the amplitude of the arm frame is cut down
選擇比值較大的結構參數為設計變量,以一階頻率為性能約束,進行了旨在提高一階固有頻率的優化設計,提高了泵車的一階固有頻率,使一階固有頻率盡可能高於油缸沖擊載荷的頻率,從而減小泵車臂架系統的振動幅度。The response that the arm frame is affected by different brunt load is observed through changing the peak of brunt load. so lowing the dynamic load ' s peak is a mean to solve the problem that vibration is too big
通過改變油缸沖擊作用的峰值,觀察臂架機構在不同油缸沖擊載荷作用下的響應,可知減小泵車油缸沖擊峰值也是減小臂架振動的有效途徑之一。分享友人
