Gearbox case is a complicacy detail. now its dimensional form and position parameter is measured ordinary by three - dimensional measuring machine. efficiency is very low
變速箱殼體是一個形狀復雜的大尺寸零件，目前國內外企業多數使用三坐標測量機對其尺寸和形位參數進行檢測。 -
This paper introduces design scheme of measurement system and establishes geometric parameter measurement patterns and functions of gearbox case, which are fit for the computer on - line automatic processing. measuring circuit and software are also introduced which are designed to carry out performance of the instrumentation
文中提出了變速箱殼體綜合檢測方案，給出了變速箱殼體幾何量測量方法，建立了變速箱殼體幾何量參數測量數學模型，推導了測量方程，對測量電路、實現整機功能要求的軟體結構給出了相關論述。 -
Now developing successfully “ gearbox synthetic inspection instrumentation ” can measure simultaneously the first and second bearing bore diameter and verticality parameters of gearbox case. information acquisition and data processing is controlled by computer. the instrumentation improves the inspection efficiency and meets the demand of mass - produced
本課題研製的變速箱殼體綜合檢測儀可實現在線檢測變速箱殼體一軸軸承孔直徑、二軸軸承孔直徑、一軸端面垂直度、二軸端面垂直度等幾何參數。 -
An automated de - noising algorithm based on the energy of wavelet packet not donoho ' s threshold algorithm is established. a gear feature vibration signal extraction method using the wavelet packet energy is proposed, which can separate gear meshing vibration, noise vibration and gear fault vibration signal from the original gearbox case vibration signal. basis pursuit ( bp ) algorithm is introduced into the filed of mechanical signal de - noising and feature extraction for the first time
第三章擺脫了donoho的閾值消噪思想，從能量的角度建立了基於小波包的自動消噪演算法；提出基於小波包能量分佈的齒輪故障特徵信號提取方法，可以將齒輪嚙合振動信號、干擾振動信號以及故障沖擊振動信號從原始齒輪振動信號中分離出來；首次將基追蹤消噪演算法引入到機械故障信號的消噪與特徵提取上，通過對齒輪故障信號的消噪，表明了它的有效性，並對影響該方法實際應用效果的因素進行了全面的分析，同時也指出了該方法存在的局限性。 -
