초록
This study attempted to experimentally confirm the change in damping force for a prototype self-leveling damper with a pump rod and a leveling port applied with a new spiral flow path for small and medium-sized electric SUVs. The faster the excitation speed of the piston rod, the higher the damping force during compression and rebound and it can be seen that the graph shape appears in a similar pattern. Based on this, it can be used as basic data for additional characteristic tests such as temperature, sliding resistance, and operating sound test, etc.
