Automated Guided Vehicles (AGVs) container are self-driven electric vehicles that are used to move material from one place to another. One of the goals of the AGV system is to reduce the dwelling time or the time from the container is lifted form the ship to leaving the storage area. One of the most important systems in AGV is the braking system. There are two types of braking used in AGV, namely frictional braking and regenerative braking. Regenerative braking is one of the advantages of electric vehicles that non-electric vehicles do not have. To coordinate that two types of braking, a series regenerative braking strategy in used, which emphasizes the use of regenerative braking. One of the output of this undergraduate thesis is the pressure on the caliper cylinder for each disc brake on each wheel. To calculate the pressure on the caliper cylinder, you must know the required braking force and torque, its distribution for each wheel, and also the proportion of frictional braking and regenerative braking. The calculations were carried out using the quasi-static method and the d'Alembert principle From several operating conditions considered, the maximum braking force required for one AGV container is 462.5 N. For the operating conditions when the AGV is running straight, the average proportion of braking force for the front wheels is 52.75% and for the rear wheels is 47.25%. For the operating conditions whe the AGV is turning, the proportion of braking force for the outer front wheel is 31.3%, for the inner front wheel it is 21.22%, for the outer rear wheel it is 28.78%, and for the inner rear wheels is 18.7%. The maximum pressure the caliper cylinder is 457.4kPa.
