一部機車連同騎士加起來的重量至少超過 140 公斤，在巡航速度達時速100 公里時，如此重的物體的動能是非常龐大的，要能在短時間內制住此鉅大動能的 運動體需要非常有效的制動裝置，而煞車系統的設計便滿足了這個需求。煞車系 統是利用摩擦的原理，在煞車時摩擦產生的廢熱會使煞車盤的溫度急劇升高，而 高溫將使摩擦係數下降，進而影響煞車性能，本研究主要針對機車的碟式煞車系 統建構溫度量測實驗平台，進行一系列的紅外線熱影像溫度量測與分析，利用紅 外線熱像儀量測在各種不同轉速下之煞車碟盤及煞車蹄片於開始制動後之溫度 場分佈情形，做為後續改良機車通風煞車盤散熱設計的基礎。

The total weight of a motorcycle and a rider is at least more than 140kg. When the speed reaches 100 kilometers per hour, the kinetic energy of such heavy object is very large. To stop such moving object within a short period of time, it needs a very efficiently equipment. The braking system can satisfy this requirement. The principle of friction is used for the braking system. When the braking system is operating, it will generate high heat to raise the temperature of the brake disc. The high temperature of the brake disc decreases the friction coefficient and then influences the brake performance. The major purpose of this project is to build a temperature measurement experimental platform for the motorcycle brake disc system. The infrared thermal camera is employed to measure the temperature distribution of the brake shoe braking the brake disc under different rotational speeds. The relevant results obtained from a series of experimental tests can be the cooling design base to improve the motorcycle braking system.
