Description
Summary:•Methodology used to minimizing suspension of a vehicle for different velocities.•Investigate effect of orifices on the damping force at different velocities.•Three different orifices opening to conduct experiment analysis.•Auto mobile damper results of two, six, and ten-orifice opening are compared. The liquid flow through orifices produces larger damping, whereas the cushioning effect comes from the fluid’s compressibility. The hydraulic damper design is subjected to constant high pressure necessary to achieve the required forces, which drastically increases during the dynamic operation. Damper has different orifices or piston valves that lead to different flow losses. The main objective behind this work is to investigate the effect of number of orifices on the damping force at different velocities for rear side two-wheeler automobile mono tube damper. Three different orifice opening cases are considered for simulations and experiments such as two-orifice opening, six-orifice opening and ten-orifice opening.
