according the principle of sympathetic vibration the new type brake hub fatigue testing device has the fatigue testing by the way of electromagnetic prompting.
新型汽车剎车制动毂疲劳试验机采用电磁激励方式,应用机械系统共振的原理进行剎车制动毂疲劳试验。
unlike the traditional idea that the failure of brake hub is mainly caused by abrasion, it is discovered that the main failure mechanism is the cracking caused by temperature different fatigue.
the rim, spoke and the brake hub are cast into a whole; the spoke takes a shape of an arc on the whole.
所述的轮辋、辐条及剎车毂铸造成一个整体,所述辐条整体呈弧形。
the results show that the failure of the brake hub is caused by the improper heat treatment operation.
结果表明,剎车轮毂的失效主要是由于热处理工艺不当造成的。
for matching the demand of local carmakers , it is discussed in this paper that the software and hardware designing and the principle of the new type brake hub fatigue testing device of car.
