  1. The first one : fitting together ultimate values of every dimensions in one dimension - chain one by one, educing many equations by itself, calculating results, and comparing these results of close dimension to find maximal and minimal values. the second one : projecting all dimensions on two preestablished axis, then providing the solutions to analyze whether every projected dimensions is increscent or decreasing, and synthesize the effect of every projected dimensions to close dimension, educing many equations by itself, at last calculating the result of close dimension. the third one : according to monte carlo analysis, getting every dimensions " values from every dimensions " tolerances at random time after time, simulating the actual circumstances of mass production using these dimensions, and calculating reasonable results of close dimension economically

    鑒于這類系統在各大中小企業的廣泛應用與相對滯后的研究水平,本文提出了三種新的能切實地解決目前尺寸鏈計算機輔助分析解算中存在的各種難題的設計方案,第一種方案將尺寸鏈中各組能取的極值組合起來,自動列方程組,求解每個組合情況下的封閉尺寸,最後比較這些結果,得出封閉的最大最小值;第二種方案將尺寸鏈各組先設定好的兩個方向投影,之後再分析各尺寸投影分量的增減性,並且提供了組兩個方向上的投影分量增減性不一的復雜情況下的解決辦法,綜合組各投影分量的增減性,然後自動列出方程組,最後根據各組的投影分量以及所列的方程組來確定尺寸鏈封閉的尺寸;第三種方案以蒙特洛法為原理,在尺寸鏈各組的取值范圍內使用計算機產生大量隨機數,模擬實際大批量生產中的零件尺寸分佈情況,以更經濟更合理的方式分析、計算封閉尺寸。
  2. According to the structure characteristics and motion rules of the new type nursing robot, the close loop control system of this new type nursing robot is designed and made with the virtual instrument developing software labwindows / cvi, mcu, piezoelectric ultrasonic motor and high precision optical incremental encoder, which can make the robot reset and rotate by the predefined tracks. at the same time, in order to make the nursing robots used more widely where intensity, precision and price are not high, another control system is designed with the step motor, virtual instrument developing software labwindows / cvi, multi - function daq card pci1711, linear power amplifier. in order to use the nursing robots in acupuncture therapy, a simple finger is designed

    在對其結構特點和運動規律分析的基礎上,本文以虛擬儀器編程語言labwindows / cvi為軟體開發工具,以單片機為控制核心,以超聲電機為驅動元件,以高精度光電編碼器作為速度和角位移檢測裝置,實現了機械臂的復位以及定軌跡的閉控制系統的開發;同時為適應一些強度不大、精度要求不高的應用場合,也為降低本,簡化控制裝置,推動新護理機械臂短期內應用推廣的需要,以目前應用較為廣泛、控制技術較為熟的步進電機為驅動元件,用labwindows / cvi開發境、 pci1711數據採集以及線性功率放大器開發了一套控制系統,實現了手臂的復位、勻速運動以及定軌跡的控制系統;為推廣護理機器人在針灸理療中應用,設計了簡單的手指機構並利用labwindows / cvi開發境,以及智能材料驅動器? ?層疊式壓電驅動器,進行了手指的抓取以及對驅動對象的轉動控制。
