Using an inerter to enhance an active-passive-combined vehicle suspension system

• A novel active-passive-combined control approach integrated with an inerter is proposed, to improve the trade-off between dynamic performance and requirements. Automotive suspension design taken as example, analytical expressions for indicators obtained using Lyapunov equations . Pareto optimality improvement a simple inerter-based combined absorber. The optimal passive layout of absorber, consisting inerter, spring damper pre-determined complexity, identified, achieving further pareto improvement. Performance vehicle can be improved help active actuator, however, potentially problematic requirements, such high energy consumption large actuator forces. To maximize benefits without requiring significant efforts, parts need designed work synergistically. In this paper, vibration suppression which part enhanced by proposed improving Via approach, configuration inerter(s), spring(s) damper(s) numbers parameter identified. demonstrated case study where considering quarter-car model typical controller (i.e., skyhook control). It will shown that, compared conventional spring-damper, adding in parallel significantly ride comfort power (or force) systematically exploring all network possibilities complexity via structure-immittance technique. This also applicable other engineering structures.
