Compared with traditional mold oscillation device, this system can conveniently change oscillation wave and alter on - line oscillatory frequency and magnitude according to the continuous casting technological requirements
與傳統的結晶器振動裝置相比,該系統能夠根據連鑄工藝要求方便的選擇波形,並在線改變振動頻率和幅值。At the same tune, the paper analyses and discusses the control projects of the above parts. as for the hardware of the control system, on principle of reliability and considering the badly working condition of the vibratory roller, the paper chooses the special controller sp ecializing in the realm of construction machinery ' s control system in order to insure the reliability of the control system and simplify it. about the control quality of the system, the paper establishes the mathematical modes of the frequency modulation system and the amplitude modulation system, analyses the irrationality of the amplitude modulation project, puts forward to apply proportional - integral - differential controller ( pid controller ) to the traveling system and frequency modulation system
作為控制系統的方案設計的基礎,本文首先對影響壓實效果的振動參數進行了分析;然後針對智能振動壓路機的功能要求,將控制系統分為壓實參數的自動和手動控制、行走控制、轉向和蟹行控制以及智能灑水控制等幾個部分,對各部分的控制方案進行了分析對比和論證;在控制系統硬體設計方面,以可靠性為原則,考慮到振動壓路機的惡劣工況,選擇了專用於工程機械控制領域的專用控制器,使系統的硬體設計得以可靠性保障和簡化;針對控制系統控製品質問題,建立了調頻和調幅系統的控制模型,對調幅系統的控制不合理性進行了分析,提出採用pid控制器對行走和調頻系統進行校正;在軟體設計方面,對各個控制部分進行了軟體編程流程圖設計。First please make sure the useful signal has very good snr before you input it to amplifiers chain, then you can calculate how much gain and nf you need to get the targeted signal amplitude and noise level, based on this you can choose the right components to design amplifiers chain
后才將其輸入放大器鏈,接著計算獲得目標信號振幅和噪聲水平所需的增益與nf的大小,最後根據這些數據選擇合適的器件設計放大器鏈路。The vibration magnitude can be reduced by applying the shock vibration absorber in boring process, the curves of the amplitude versus gap between the shock block and the hole in boring bar was gained by experiments with different cutting speed. the experiments show that the absorptive results is good when applies shock vibration absorber with suitable gap in boring process, while the vibration may be strengthened with unsuitable gap. 6figs., 2tabs., 3refs
通過試驗研究,得到了在不同切削速度的情況下,沖擊塊與孔壁之間的間隙與切削振動幅值的關系曲線,研究說明,沖擊式減振器在適當的值范圍內減振效果明顯,但如果選擇不合適,則有可能使振動加強.圖6 ,表2 ,參3Amplitude selection amplifier
