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(duì)數(shù)控銑削加工仿真的切削過(guò)程幾何表示及真實(shí)感圖形顯示算法進(jìn)行了深入研究,提出并實(shí)現(xiàn)了一種數(shù)控銑削仿真切削過(guò)程幾何表示及真實(shí)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(shí)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(shí)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(shí)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(yīng)用圖形顯示算法并結(jié)合小波變換快速算法將信號(hào)分解到不同的頻帶上,且分解結(jié)果和原信號(hào)長(zhǎng)度保持一致,可對(duì)信號(hào)進(jìn)行深層次的處理,克服了傳統(tǒng)的信號(hào)處理方法不易提取微弱信息的不足.通過(guò)對(duì)礦用斜軸式柱塞泵振動(dòng)信號(hào)的分析,分離出了配流副磨損、球鉸松動(dòng)、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(hào)提取及設(shè)備的早期故障診斷提供了一條有效途徑
