National Tsing Hua University
技術說明:
「學生方程式賽車」是全世界最大的工程設計競賽,至今已舉辦超過四十年。在此競賽中,學生必須根據FSAE(美國機械工程師協會)公布的規則,自行設計和親手製造出一台合乎規格的賽車。賽車種類有分為內燃機(ICV)賽車和電動賽車(EV),雖在規則上有相當大的難度差別,但是兩種類賽車的名次為一起混合排名。評分項目除了有車輛動態項目還有靜態報告項目,動態項目有直線加速、八字繞環、耐久賽等;靜態項目則有成本、設計和商業報告,因此學生方程式賽車是一個相當龐大的多系統整合工程,更是一個有挑戰性的跨領域合作。這個賽事在美國、德國、英國、日本等工業強國都有舉辦,清大賽車工廠自2016年開始以內燃機賽車參與日本賽事,至今(2019年)已是第四年參賽,每一年都在技術上持續有相當大的突破,2018年我們同時挑戰製造了兩台賽車(內燃機賽車和電動賽車)前往日本比賽,兩台車皆成功地通過日本嚴苛的車檢,並完成所有比賽項目。在電動車技術中,我們自行開發了BMS電池管理系統,也成功獲得日本評審的肯定,而國外隊伍則多使用市面上現成的電池管理系統,相較之下,這也直接證明了我們團隊自行開發產品的專業能力和可靠度。
2019年,我們決定全心投注於電動賽車的研發,除了因應未來的產業趨勢,也希望能夠往技術難度更高的層面挑戰。我們沿用去年開發的電池管理系統電池;修改車架以符合新的電池擺放位置;優化電池箱設計,使整體結構更安全,也能容納更多的電池芯來提高動力電壓;在懸吊系統我們採用全新的設計,將Roll、Ride兩種不同的車輛動態獨立由不同的避震器來吸收能量,因此車輛動態表現將會更加優異;Wishbone的材料則由以往的鈦合金管更改為團隊研發已久的碳纖維管,並經過無數次的強度實驗來驗證安全性,將可使懸吊系統更輕量化且強度更強;空力套件則捨棄了前尾翼,但使用導流板 (Diffuser),在不到2公斤的重量增加之下,增強了車體下壓力以換取更佳的抓地力。

Student Formula is the largest engineering design competition worldwide, dating bac to more than 40 years ago. The students are tasked with designing and manufacturing their very own formula race car according to the rules mandated by the FSAE. The competition is sub-divided into two categories: Internal Combustion Vehicles and Electric Vehicles. Despite differences in the level of technological difficulty, vehicles of the two groups are often ranked together. The teams compete in both dynamic and static events, with the dynamic tasks including acceleration, skip pad, autocross, and endurance, while the latter consists of design, cost, and business report. This proves that Student formula is more than merely an engineering challenge, it is a collaboration across multiple disciplines. Currently, the competition has stations in industrial leader nations such as the US, Germany, England, and Japan; and NTHU Racing first entered the race in 2016, competing in the ICV category. In 2019, we have officially entered our fourth generation, and each year we’ve strived to make significant leaps in terms of our design and technology. In 2018, we successfully completed two cars, both ICV and EV simultaneously, both of which passed the rigorous inspections and dynamic tasks. More notably, for our electric race car, while most teams utilize commercial battery management systems for their design, we developed our very own system to be integrated onto our race car, which widely gained acknowledgement from the judges and panel members.
In 2019, to follow the trend of future automobile development and to take our technology up a notch, our team decided to focus only on the development of a single EV. We inherited last year’s BMS architecture; modified the frame design to cater to the new battery position; we also improved our battery infrastructure design, improving the overall safety, and also increasing the total voltage by accommodating more battery cores; we completely redesigned the suspension system, distributing the control of the roll and ride motions to respective shock absorbers, enhancing the dynamic performance of the car; we also successfully changed the wishbone into carbon fiber material after rigorous testing to ensure its safety, decreasing the weight of the suspension system but making it stronger at the same time; for our aerodynamics design, we decided against front/ rear wings and added on diffusers instead, gaining significant grip at the cost of no more than 2 kilos of additional weight.
