摘要: 在籃球比賽中,進的球越多就能得到越多分數,而得到越多分數再配合嚴密的防守,就有很大的機會贏球。進球的方式有分三種:投籃、上籃、與灌籃,本研究討論的即為投籃過程的手部動作。在參考幾篇相關文獻後,便能知道標準的投籃動作。但是文獻中提出的標準投籃動作裡,似乎又細分出分四種看起來相差無幾的動作。為了瞭解哪種才是最標準的,就以SolidWorks建構出人體模型,緊接著以COSMOSMotion進行此四種投籃動作的模擬,由模擬結果便知道了哪一種動作投出去的球的偏移量最少,就是「最標準的投籃動作」。然後就根據此最標準的投籃動作,用機構合成的三個位置合成,設計出能限制並帶動手臂做出一樣動作的輔具。為了驗證本輔具有達到效果,以SolidWorks建構出輔具的模型,並與人體模型組合,然後以 COSMOSMotion進行投籃的模擬。最後由模擬結果可看出手臂的動作確實有被矯正,而投出去的球因為手掌並沒有完全被輔具拘束住,所以造成球還是有一點點偏移,但其偏移量又比最標準投籃動作的還要小,因此證明穿戴本輔具投籃可以投得比較準。
The more field goals you get, the more points you get. If you get many points with strong defense, you will have great opportunities to win the game. There are three ways to get field goals: jump-shooting, layup, and dunk. This thesis discusses the arm’s movement of jump-shooting. We can realize standard basketball shooting movement by consulting some references. But there seem to be four kinds of standard shooting movement which have little differences. In order to find out which movement is the most standard, I use SolidWorks to construct a human model and then use COSMOSMotion to do dynamic simulation of these four shooting movement. The shooting movement which makes the ball producing least deviation in simulation is the most standard shooting movement. Then I base on the most standard movement and use three position synthesis of mechanism synthesis to design an orthosis that can lead arms to do the same movement. In order to verify whether this orthosis works, I use SolidWorks to construct the orthosis model. Then I combine the orthosis model with human model, and I use COSMOSMotion to simulate basketball shooting. In the end, we can know from the result of simulation that the arm’s movement is corrected and the deviation of the ball is smaller than the human model without orthosis.
