Metro Kapsul is a solution to traffic congestion by providing mass rapid transport. It is developed by PT TreKKa, a local industry. The vehicle or train is autonomous and moves on a concrete track. The electric train or capsule travels following the guide-wheel as it traces the concrete guide. Therefore, the main steering mechanism is the guide wheel. To synchronize the movement, there is a pair of symmetrical left and right steering mechanisms which act as a passive steering. In this bachelor thesis, a kinematic and dynamic analysis of the passive steering is carried out as a continuation of the previous thesis. The analysis needs to be performed considering the redesign of the steering system and mechanism. The analysis was carried out using the vector loop-closure method. In this case, a four-bar mechanism is constructed based on the hinges available in the left and right steering mechanisms. In addition to kinetic loads, forces as a result of tireroad interactions are taken into account. Specifically, the total moment of tire scrub and jacking moment is calculated. Upon completing the analysis, it turns out that the connecting rod experienced the largest load and it is compressive. However, this force is still much smaller than material’s strength and buckling limit of the rod. Another thing to note is that the vector loop-closure is inadequate in modeling the complete mechanism. In the future, it is recommended to use multi-body dynamic software for the analysis.
