Almost vehicles have parking systems that function to set safety devices and driving modes, which exist in the form of gear knobs, button types, and rotation types. Here, the driving mode is familiar with the form of P-R-N-D-S, and recently, it has changed into a simple system of P-Not P mode. This can be expressed as a shift by wire (SBW) type that operates the gear knob with a human hand (SBC: Shift By Conventional type), and the mechanical principle driven by each range is the same. This system is designed to prevent the sprag from rotating the gear when the parking gear is stopped (P), and the sprag must bereleased from the gear to drive the vehicle when driving or reversing (D or R). In addition, parking on ramps requires more force than flat ground, so it has been calculated through design sheets or multibodydynamics analysis to calculate the force required to operate this system. In order to check various designs, it is difficult to respond through the simulation of a parking system using a rigid body in order to review the life of a flat spring mounted on the operating system. In this paper, a method of predicting fatigue life was presented through test and flexible body dynamics analysis (Ansys motion) to expect the flat spring durability of the operating system during the initial layout design stage of the new parking system to improve this problem |
