A New CRONE Suspension: More Compact and More Efficient: Part 2—Synthesis and Achievement

In a vibration isolation context, fractional derivative can be used to design suspensions which allow to obtain similar performances in spite of parameters uncertainties. This paper presents the synthesis and the achievement of a new Hydractive CRONE suspension system. After the study of the different constraint in suspension in the first paper, the ideal transfer function of the hydractive CRONE suspension is created and simulated in different case. Then a method to determine the technological parameters is proposed. A parallel arrangement of dissipative and capacitive components and a gamma arrangement are compared. They lead to the same unusual performances: the stability degree robustness and the rapidity robustness.

A New CRONE Suspension: More Compact and More Efficient: Part 1—Problematics and Specifications

This paper presents, in 2 parts, a new CRONE suspension approach. The first part defines the problematics in suspension and gives the different conditions to overcome it. Then in the second paper a new CRONE suspension system is synthesized based on the conclusion of this paper. So, here, is presented how the variations of mass act on the classical suspension and how tools can be set up to simulate the influence of this variation without to choose the technological structure. Then a criterion on the level of wheel holding is established.
