Steer-by-wire (SbW) systems eliminate the mechanical connection between the steering wheel and the road wheels, increasing the importance of physical safety mechanisms. In SbW systems, the steering feedback actuator (SFA) is responsible for generating steering feel and requires a mechanical device to limit the steering wheel rotation under abnormal conditions. In this study, a mechanical end stop (MES) structure for the SFA is proposed. The structure and operating mechanism of the proposed MES are described with a focus on rotation angle limitation and load transfer characteristics. To evaluate the structural integrity of the proposed design, strength analysis was conducted. In addition, fracture tests using an SFA assembly were performed to assess the fracture behavior of the MES under steering load conditions.
