Abstract

Automotive door locking system is one of the most important things to be considered in safety precaution of vehicle. During crash test, the components of the door locking system that consists of latch, striker, cylinder key, lock knob, inside/outside door handle and linkages must sustain it position and function which is to ensure that the door did not open and keep the occupant safely inside the vehicle. By studies the theoretical of dynamic behavior of the system during impact, it helps to solves and minimizes the probability of passengers being ejected from a vehicle in order to fulfill the requirements of standards and regulations that had been established (FMVSS, 2004). In this case studies had been refer on the United States of America Federal Motor Vehicle Safety Standard No. 206, Door Locks and Door Retention Components (FMVSS No.206). By using dynamic inertia calculation, 30g load exerted vertical (worst rollover) and lateral (side) directions. In assumption, the door considered pass both impact directions when got the result in positive value unless got negative value, it considered fail. The results showed that, the door locking system pass the 30g impact test in lateral direction which is +3.105Nm. However, the continuous action has been taken on vertical direction but obtained the fail result which is -0.0734Nm. For the other method by using CAE simulation, applied conditions still same as 30g load will be exerted vertically and laterally. The result obtained show that the value of angular velocity of every part equal to zero means that there have no rotation motion during impact. Hence, the test considered passed for both directions. Both methods are correct and follow the requirement of FMVSS No 206 and UNECE Regulation No 11.
