“…By reducing the stiffness of the system, the resonant frequency can be lowered, while increasing the damping can reduce the amplitude of the peak resonance; however, this is detrimental at higher frequencies. [16] This evaluation fits with analyzing a linear stiffness situation, and it is seen that a lower stiffness will result in a larger frequency range for vibration isolation. [29] In a nonlinear system, the relationship still informs the systems capabilities for each stiffness region.…”

“…[14,15] Most QZS systems employing nonlinear stiffness to achieve a QZS region rely on standard linear vibration isolators but employ nonlinear components to achieve a net QZS. Other systems that exploit QZS for vibration isolation include magnetic springs, [16,17] magnetic and pneumatic spring mechanisms, [18] cam-rollers, [19,20] cam-roller-spring-rod mechanisms, [21] and systems employing pairs of oblique springs. [22] Ma et al conclude that passive vibration isolation systems have excellent lowfrequency vibration isolation performance when tuned for the application, while active vibration isolation systems are better suited to variable conditions.…”

This research introduces a novel approach for reducing the vibrations experienced by passengers in vehicles using metamaterials embedded in polyurethane foam to improve the existing vibration isolation capacity of car seats. An exploration of quasi‐zero and negative stiffness metamaterials has been conducted to develop metamaterial springs that exhibit a region of high‐static and low‐dynamic stiffness to achieve vibration isolation. Metamaterials were developed using low‐cost open‐source additive manufacturing methods and thermoplastic polyurethane filament. This investigation followed a process of determining the geometric, material, and systemic design requirements, to identify the quasi‐zero and negative stiffness force‐displacement regions. Small‐scale models of a car seat were developed by embedding the designed metamaterials into different grades of polyurethane foam and completing static and dynamic testing. The results demonstrated practical applications for implementing metamaterial springs into polyurethane foam to enhance vibration isolation under dynamic loading. The developed material library, and the key geometric variables in the metamaterial design allow for application specific solutions where the selection of the appropriate metamaterial and foam combination can be tailored to suit the system requirements.This article is protected by copyright.

A novel bio-inspired kangaroo leg structure for low-frequency vibration isolation

Inspired by the vibration mitigation effect of kangaroo's legs, a novel bio-inspired kangaroo leg structure (BKLS) is proposed for low-frequency vibration isolation. The BKLS is composed of two main rods with different lengths (simulating the calf bone and thigh bone), two linear springs (simulating the internal and external muscles) and two auxiliary rods. The dynamic model is established based on the Lagrange principle to describe the nonlinear effects of BKLS, which are mainly contributed by the internal and external springs and the rotary joints. Experiments were carried out to verify the theoretical predictions and demonstrate that the proposed BKLS indeed possess superior low-frequency isolation performance without sacrificing the carrying capacity, which can effectively suppress vibration with frequencies higher than 1.06 Hz. Regardless of the isolation mass and the excitation conditions, the vibration isolation performance can be significantly improved by selecting appropriate structural parameters. The innovative and simple BKLS provides an effective method for low-frequency vibration isolation.
