After introducing some backgrounds and the state of art of motion editing and motion synthesis, we introduce some basic operations of motion editing and show implementation results in eidolon. chapter 3 describes inverse kinematics, and two real time algorithms : ccd and jacobian transpose are discussed in detail. in chapter 4, we introduce the principle of multiple level b - spline, and motion path editing is achieved with such spline
在介紹了運動編輯和合成的一些背景知識和研究現狀后，本文第二章概述了運動編輯的一些基本操作並給出了在eidolon中的實現結果；第三章介紹了逆向運動學演算法，著重講述了兩個具有實時性的演算法：循環坐標下降法和雅克比轉置法；第四章詳細介紹了多層次b樣條原理和用其進行運動路徑編輯的方法。With the increasingly extensive application of the planar enveloping hourglass worm gearing, it becomes more important to rapid detection and high precision of the manufacture error. the surface of the planar enveloping worm gearing is complicate, and current domestic and international examination concerning its form generally is recur to the general three dimension measure apparatus or the special measure apparatus according to " the type of assemble " principle designed
由於平麵包絡環面蝸桿齒面比較復雜，其齒形、齒距、齒厚各不相等，因而關於它的製造誤差檢測也比較復雜。目前國內外關于其形面的檢測一般是藉助于通用三坐標測量機或按「裝配式」檢測原理（即測量狀態與加工狀態一致的原理）設計專用量儀進行的，一直沒有十分成熟的專門產品問世。On introducing the development of cmms, this paper proposes a new concept - virtual coordinate measuring machine ( vcmm ) in application of virtual reality, expounds the concept, construction and building method of vcmm, describes the running environment of moving bridge vcmm
本文簡要地介紹了傳統三坐標測量機發展的現狀，結合虛擬現實技術，提出了三坐標測量機的一個新的發展方向虛擬坐標測量機（ vcmm ） ，同時闡述了虛擬坐標測量機的概念、組成和實驗方法，並說明?活動橋式虛擬坐標測量機的運行環境。Likewise ， some “ way out - of - shape ” individual （ i. e. unable to do even a few pull - ups ， push - ups ， abdominal crunches ， etc. ） would be better off engaging in a period of standard circuit training to improve general conditioning
同樣的，一些「沒有體型」的個人（例如，甚至不能做幾個引體，俯臥撐，仰臥起坐等）進行一段時期的為改善整體身體狀況的標準訓練循環會好起來的。In dtc system, the concept of space vector is introduced to analyze and control the ac motor, the electromagnetic torque and flux are caculated and controlled in the stator reference frame, and the optimal pwm gating signas are generated to control the inverter according to the output of the bang - bang regulator. in this paper, the dtc system is designed based on dsp. a speed estimation method is derived detailedly and the sensorless speed close - loop control is conducted. in this system, there are some problems, such as flux drift and torque ripple. to resolve these problem, a modified flux caculation method and some measures such as speed lpf, torque slide filtering are adopted. the system performance is enhanced by these mersures
直接轉矩控制採用空間矢量的概念來分析異步電機的數學模型和控制其各物理量，直接在定子坐標系中計算和控制轉矩和磁通，藉助于離散的兩點式調節（ bang - bang控制）產生pwm信號，直接對逆變器的開關狀態進行優化控制，以獲得轉矩的高動態性能。本文採用dsp設計了直接轉矩控制系統，詳細推導了速度估計方法，進行了無速度傳感器的速度閉環控制。分享友人
