  1. From theoretical analysis, we know the existing demodulation methods have limitations as following : one is that the subtraction of the two signals frequencies will display as the result of demodulation when we demodulate two time - domain adding signals without modulating information ( fault information ) ; the other one is that aliasing phenomenon will occur as a result of getting absolute value, detection or square in the process of generalized demodulation analysis, such phenomenon will result in some superfluous frequency composition on the frequency spectrum, which will puzzle the detec tion of mechanical vibration. if the sampling frequency is selected from a suitable range, the aliasing phenomenon will be avoided ; the last one is that aliasing frequencies will be produced in zoom demodulation analysis because this algorithm cannot employ digital low - pass filtering to avert the folding frequencies of higher harmonics in the process of zoom sub - sampling

    現有的解調析方法存在以下三種局性:將不包括調制信息(故障信息)的兩時域相加信號,也以其頻率之作為解調信號而解出;廣義檢波濾波解調析中,由於取絕對值、檢波或平方過程可能產生混頻效應,在解調譜中表現為無法析的頻率,並由此推導出避免這種混頻現的采樣頻率的選取范圍,從根本上避免此類診斷的產生;幾種細化解調析新演算法中,因為無法在細化析的選抽時進行數字低通濾波,有可能會出現調制頻率的高次諧波發生頻率混疊而反折到低頻部的現
  2. The software can design many conventional type of cam, concluding cam - plate with middle follower, cam - plate with offset follower, cylindrical cam, dividing cylindrical cam, and cylindrical cam with space curve, etc. in forming working curves of cam - plate, used the approximation by arcs which can lessen the nodal points on curves of cam uttermostly in same error, so it reduce the computation time and relieve the chattering of principal axis. in former times, to cam mechanism, the follower only has one direction motion

    本軟體可以設計的凸輪類型較多,包括了對心移動從動件盤形凸輪、偏置移動從動件盤形凸輪、圓柱凸輪、圓柱度凸輪和空間曲線柱形凸輪等,其中對盤形凸輪的工作曲線採用了難度較大的圓弧逼近演算法和等演算法,這樣就可以在相同的允許內最大度的減少生曲線的節點數,減少計算時間,同時可以大大減輕加工中的振動現
