Intelligent Structural Design of Transport Pneumatic Suspensions with Extreme Characteristics

The efficiency of transport pneumatic suspensions can be drastically increased in a range including near-zero frequencies by joining redundant mechanisms that provide extreme characteristics of stiffness (control from “negative” to near-zero values). However, such structural redundancy can result in worse efficiency, and the suspension could become the vibration amplifier rather than the isolator. This paper presents an approach to avoid the influence of the structural redundancy and fundamentally increase the efficiency in topmost frequency ranges. The approach includes a theory of structural design and practical schemes of viable redundant mechanisms. An atlas of new candidates of perfectly structured suspensions with extreme characteristics is elaborated. All the structures appear in the atlas as result of enumeration by avoiding empiricism. The utility of the approach is demonstrated in terms of the design and comparative testing of seat pneumatic suspensions.
