【正文】 Accounts for 3 at home in the post with high technical advantage is invented. 6%, and accounts for 96 abroad. 2%. Second, the one that strengthened to the market of our country was monitored . In order to safeguard its one39。 This year, at the rich meeting of German body, the exhibit of another enterprise of ours is asserted and infringed, the other side must speak to and does not five people , our enterprises admit a fault , ready to pay the penalty and does not miss , and humiliate this enterprise by every means in public , pass the diplomatic channel finally, the embassy negotiates, has dealt with this . Happen when this kind of case is on our country39。 patent for invention of infringement at all, Make the bringing the doctrine and entering into the mistaken idea in vogue for a time of sports goods industry of our country too. Do it in this way, in paratively close planned economic system, may little someone find or investigate , but today, the gateway of a country is opened further, we must pay a price for this . In 2021, our family participated in .39。t annual increment, a lot of urban and rural residents growing rich choose this superior way of building up body one after another , the race apparatus designed in large quantities 35 of humanization is ing out, improve through electronic technology , the technology of the puter , transformation of making the equipment frock , its development space is very big, is a kind of products with sustainable development prospect Three major key elements of promoting national economy to increase healthily are consumption , investment , export. The development of and the electronic race apparatus, occupy very great proportion among them. One that is with domestic Engel coefficient constant to reduce, by clothing,food,lodging and transportion to raise life quality develop people, the electronic race apparatus will be the optimum seeking apparatus of patriot39。s sticking brand production , improved the domestic occupation rate of the electronic race apparatus greatly, have offer for numerous enterprises and develop samples too, has driven the flourishing development of the whole trade. The electricity runs: Fashionable bodybuilding products of the fairly fortable life At present, enterprises which produce the electronic race apparatus centre in the coastal area of the Changjiang Delta , Shandong Peninsula , Guangdong , Fujian, the total amount is about more than 50, it is about 15 that possess scale among them, and the jointventure , proprietorship account for 50%. The electronic race apparatus is the integrated products of electromechanics, adopt assembler language programming, control with the puter, it is the development trade that the country encourages . The development of this product has driven making, plastic products , electronics industry of steel tube , electrical machinery industry ,etc. series develop , make people health is it limit by place , environment , climate to do exercises, contain physical training in recreation amusement, improve the national physique in an allround way. In this production course, there are not pollutant and harmful substance that are produced , purchase the steel , plastic fittings outside, the electronic devices and ponents are assembled, is the green manufacture industry The Central Party Committee which regards Hu Jintao as the General Secretary advocates building harmonious and orderly development environment in a more costeffective manner, the development of the electronic race apparatus sticks to this theme closely, is playing an important role in driving the trade structural adjustment. Raise through the national ine entering the welloff society, the electronic race apparatus begins to enter the family too in recent years, it for example can39。 1999 英文資料 The electronic race apparatus trade calls China39。 隨著人們健身意識的不斷提高， 健身器械的需求越來越大，希望 老師能把 此課題 作為健身器械 系列課題一直做下去 ，做為開始的我無比榮幸！ 33 參考文獻 [1] 王三明主編 .機械原理與設計課程設計。 隨著時間的一天天過去，自己的成績也明朗化，終于整個結構完成了，進行 了零件的裝配，按照任務書的進度，設計也慢慢接近了尾聲， 在過程中，指導老師羅春陽做了整體把握，對細節(jié)問題給予了莫大的幫助，使設計更精益求精，對設計中沒有注意到的問題給予了指出。在零件的建模中，慢慢的自己很多模糊的東西都明顯化， 和矛盾化，需要自己去明確的數(shù)據(jù)去論證，更嚴重的是核心的東西也有可能是錯 誤的， 但值的高興的是，自己從設計中學到了很多東西，四年學習了很多，可又似很模糊，現(xiàn)在從一個產(chǎn)品開發(fā)設計的角度去學習，很多東西恍然，欣喜自己 找到了 以后 深造的方向，可以在畢業(yè)后能繼續(xù)本專業(yè)的學習。 接下來任務就是三維零件實體建模了，在軟件的選擇上，選了美國 SOLIDWORKS 公司的 SOLIDWORKS 進行了學習，此軟件的特點就是上手快， 而且在很多公司都要求會 SOLIDWORKS，因為此軟件便宜但功能還比較強大，在很多公司的設計采購里是首選，容易實現(xiàn)其普遍性 和正版化 。但是涉及到專利技術的保護， 收獲甚微，只好無數(shù)次的猜想和論證，走了很多彎路，感受到了什么叫萬事開頭難， 甚至覺的憑自己 所掌握 的知識完不成跑步機的設計，只好開始了漫無目的的收集資料。 走過彎路，想過放棄，最后還是堅持下來了。 小結 跑步機 是由電機帶動，則跑步者須與 跑帶節(jié)奏保持一致，在跑步時出現(xiàn)意外，要迅速的 使跑步帶停下來，所以在跑步機設計時要盡多的考慮安全問題。 （ 11）不要立即入浴。 （ 10）不要亂開玩笑。 31 （ 9）不要閑談。 （６）如果是為了減脂而練習跑步機，可在練習期間配合腹部力量訓練，如仰臥起坐等。 （４）訓練次數(shù)每周不要超過四次，在飯后一個小時進行為好。 （２）在練習的過程中，最好每１５分鐘就補充一定的水分，但不可太多。 2 如果想要跑步機練習變得活躍、豐富起來，可以將跑步機放置在電視機前，一邊看自己喜歡的電視節(jié)目一邊練習，或在練習時一邊聽自己喜歡的音樂一邊練習也可以，但大部分的注意力一定要放在跑步機上還可以讓家人配合，在練習時經(jīng)常給自己大聲地鼓勵，這樣可以很好地活躍練習時的氣氛。 定期地檢查跑步機的各個螺釘、螺栓及螺帽，若 有松動，請立即用工具鎖緊固定。 經(jīng)常在跑步機的各部位用干凈的抹布清潔，除灰塵，以維護各零件正常運轉的性能。 */ 圖 85 仰臥起坐架 小結 多功能的設計 表現(xiàn)在兩方面，一個是通過程序的設計 ，設計不同的模式使鍛 煉者可以進行不同程度的鍛煉，另一個是添加附屬器件，比如此設計中扭腰盤和仰臥起坐架 ，但是不是功能越多越好，必須考慮彼此不影響，保證鍛煉的準確性。 28 圖 83 扭腰盤旋轉機構 圖 84 扭腰盤折疊圖 . 仰臥起坐架的設計 根據(jù)美國醫(yī)療協(xié)會報導 ,做仰臥起坐對人體新陳代謝 有絕對的幫助 ,其可增進肺部運動量因而提升免疫力。 圖 82 扭腰盤支架 . 旋轉結構設計 此扭腰盤 選用單向推力軸承和深溝球軸承配合完成對軸轉動的的支撐。 ⑤增強血液循環(huán)，健美強身兩不誤。 ③身體隨著轉盤扭動 ，使腰部、跨部得到充分鍛煉，瘦腰美腿、保持身材。 26 第 8章 多功能設計 . 扭腰盤設計 圖 81 扭腰盤 【 特點】： ①采用 ABS 塑料 +磁鐵制成， 抗沖擊強度高，密度小，便于運輸，完全可以替代鑄件，表面光潔度好，不用噴涂，可節(jié)省費用 35 元，重量僅是鑄件的 1/7，從運費上可節(jié)省 6/7，采用此產(chǎn)品綜合成本效益可降低 4
