Simulation and theoretical Analyses of the Impact of Velocity, Pressure and Kinetic Energy during Damping in a Shock absorber

Abstract

The current global crisis of climate change has forced engineers to redesigned automotive cars that will require less fuel combustion and burning of gases to reduced pollution. This has seen energy optimization with less emission control in the automotive industries. This research study presents a simulation of the major parameters for energy regeneration in automotive hydraulic shock absorber during car operation. This involves the simulation of major parameters during damping which impacts the oscillatory motion of the car during motion into rotary motion. In the simulation process, the influence of hydraulic dynamic flow, velocity, pressure and kinetic energy during damping was taken in to consideration during simulation. Parameter such as the bulk fluid modulus, viscous friction torque, and compressive flow in fluid dynamics, motor efficiencies, and torque constant coefficients were simulated theoretically using the theory of stochastic mechanics. It was also shown that the resistance also caused a change in geometry between the working cylinder and reserve cylinder when fluid experiences a change in velocity due to turbulence. It was also shown that the fluid thickness in the damper during damping created turbulent flow and eddies which moves randomly and also affected the energy harvesting process. The drop is pressure during damping is also proportional to the square of velocity the drop in pressure due to the increase in average speed during damping and this can be related to the transfer of Kinetic Energy from the random molecular motion to stochastic mean motion
