A New Proposed Variable Stiffness of the Vehicle Suspension System Passive Case: I

A theoretical analysis of a new proposed variable stiffness model of the suspension system is studied to improve the traditional suspension system. The fundamental idea of system centered on variable stiffness mechanism by added subsystem to suspension system depended on control rotating arm balancing the force between sides, it consists of a vertical control strut. The variation of the load transfer by rotate arm has spring and damper at another side of it where the point of rotation is supplement the body of car by sup system as vertical support. The investigations of the new variable by addition stiffness to the suspension system for reaches improved performance better than the variable stiffness systems for equivalent or traditional. The expending principles to described the performance of the characteristic behavior of system are fewer car body acceleration to ride comfort and lower suspension and tire deflection for road holding considered
