Question
The stability of a motorcycle and rider is an important area for study because many
motorcycle designs result in vehicles that are difficult to control. The handling
characteristics of a motorcycle must include a model of the rider as well as one of the
vehicles. The dynamics of one motorcycle and rider can be represented by a loop transfer
function as shown in Figure 1(b).
[Kestabilan motosikal dan penunggang merupakan satu bidang yang penting untuk dikaji kerana banyak
reka bentuk motosikal mengakibatkan kenderaan yang sukar dikawal. Ciri-ciri pengendalian motosikal
mestilah termasuk model penunggang serta salah satu kenderaan. Dinamik satu motosikal dan penunggang
boleh diwakili oleh fungsi pemindahan gelung seperti yang ditunjukkan dalam Rajah 1(b).]
