3 . a simulation geometrical model and real - time and dynamic realistic picture creating and displaying algorithm was proposed and implemented . the quality of our realistic picture is nearly as good as the ray - trace 對數(shù)控銑削加工仿真的切削過程幾何表示及真實感圖形顯示算法進行了深入研究,提出并實現(xiàn)了一種數(shù)控銑削仿真切削過程幾何表示及真實感圖形顯示算法。
This system renders textile designers change all the fabric properties freely , and express ones " ideas incisively and vividly . meanwhile , this paper emphasizes the display algorithm of tightly arranged threads overlap , thread picture simulation and feather generation 其中著重介紹了紗線緊密排列,存在相互覆蓋時的顯示算法(包括同種類型的紗線相互覆蓋和不同類型的紗線相互覆蓋) ,單根紗線的平面模擬算法和生成紗線毛羽紋理的方法。
The section plane display algorithm is studied in the thesis , and the interaction section and curve section display is achieved , which can provide the aids for observation and analysis of organs . also , it is very helpful for the dose distribution analysis 本文研究了顯示任意剖面的算法原理,并實現(xiàn)了交互式的任意剖面顯示和曲線剖面顯示,這不僅能為器官的觀察、分析提供幫助,同時能為在組織器官受到射線照射后定量、定位地分析劑量分布提供很好的手段。
Abstract : in order to process signal in depth and to extract the fault feature from original signal in machinery diagnosis , the graphical display algorithm that can keep the data length of wavelet transform results the same as that of original signal is used . the fault diagnosis of a bend axial piston pump via b - spline wavelet that has linear phase is provided . the results of study demonstrate that the new method has excellent feature and the weak fault signal can be extracted from the strong vibration background of the pump 文摘:采用具有線性相位的b樣條小波,應用圖形顯示算法并結合小波變換快速算法將信號分解到不同的頻帶上,且分解結果和原信號長度保持一致,可對信號進行深層次的處理,克服了傳統(tǒng)的信號處理方法不易提取微弱信息的不足.通過對礦用斜軸式柱塞泵振動信號的分析,分離出了配流副磨損、球鉸松動、缸體及泵軸支撐軸承的故障特征,為液壓泵的故障診斷提供了依據(jù),并為信噪分離、微弱信號提取及設備的早期故障診斷提供了一條有效途徑
