Stiffness of suspension

This paper proposes a model reference adaptive control (MRAC) design for vehicle active suspension systems with unknown spring stiffness and damping coefficients with the aim of improving the performance of suspension systems. A mathematical model of a half-car active suspension system is first presented, then a reference model of a half-car suspension system that utilizes the skyhook damping concept is proposed.

This paper studies the vibration analysis of the powertrain’s four-point suspension system of light truck. The method of reseash is simulation by using MATLAB Simulink. The relationship between the system’s physical parameters (spring stiffness and damping coefficient) and the vibration parameters is then analyzed to find the best combination of the physical parameters that yields the optimized vibration behavior. An experimental of measuring the vibration frequencies at the four-point of powertrain's suspension with the engine working with different rotation.

In this paper a nonlinear quarter car suspension–seat–driver model was implemented for optimum design. A nonlinear quarter car model comprising of quadratic tyre stiffness and cubic stiffness in suspension spring, frame, and seat cushion with 4 degrees of freedom (DoF) driver model was presented for optimization and analysis.
