When compared with a gear and chain, a timing belt is an efficient element to transfer object in the system. The timing belt can move objects and the system can be operated quietly. Moreover, users can control the translation of the object precisely by the step motors and electronic control devices. But the failure of the timing belt can cause economical loss and even injure of operator. Although the design standard has been offered by the suppliers of the timing belt, users can’t predict the life of the timing belt in operating environment. We made the computer program with the life prediction method of the timing belt, and it can help the users to choose the suitable timing belt in the system.

A leaf spring suspension has been widely used since it can carry big load and its simplicity. But one major drawback is the poor ride performance because of the friction in the system and the high stiffness coefficient. To overcome these, an air spring suspension can be used. The air spring suspension system can improve the ride of the heavy vehicle significantly and also it can adjust the height to the loading and unloading. The road tests for the truck with the leaf spring suspension and air spring suspension are performed to compare the ride quality of the two systems. To develop the air spring suspension system tailored to the target truck, chassis development procedure using CAE has been applied.
