Abstract
L/UL (Load/Unload) dynamic characteristics are affected by various parameters, the friction between lift tap and ramp profiles and so on. Also, the L/UL speed is restricted and the power consumption is determined by these parameters. The mathematical governing equations are derived for four ramp step and suspension characteristics. And the experiment is carried out in order to verify L/UL dynamic characteristics when the lift tap moves along the ramp. As the results of simulation and experiment, the bias force of flex-cable is changed by ramp profile. In the case of this system, the flex cable pushes the actuator until step 3. But that pulls the actuator in step 4.
