Special Issue Information

Dear Colleagues,

This Special Issue deals with the development of adaptive systems and structures for use in vehicles, defined broadly as vehicles for ground or air transportation. The pressing need to reduce the weight of vehicle structures is motivated by current limitations in the range of electric vehicles (EVs) and the increasingly stringent emission requirements being placed on internal-combustion powertrains. In conjunction with consumer and regulatory expectations in relation to safety, environmental concerns, energy consumption, and overall performance, these needs require the development of multi-functional structures that simultaneously provide a diversity of functions beyond just mechanical integrity. Smart materials can greatly accelerate the development of multi-functional systems through the integration of actuators, sensors, and stiffness-tunable components to achieve structures that autonomously or semi-autonomously adapt to changing external conditions. This Special Issue seeks to attract original works in these areas that may focus on one or more aspects of novel smart materials, control strategies for adaptive structures, new actuators and sensors, advanced manufacturing approaches for smart structures, and innovative designs of components and systems, with the overall objective of developing adaptive structures that can contribute to the widespread transition from fossil-fuel-based transportation to EVs, air taxis, and other emerging applications in the areas of ground and air vehicles.

This Special Issue closely fits the scope of Actuators since it creates an advanced forum for the science and technology of actuators and control systems.

This study aims to examine the dynamic response of a polyvinylidene fluoride (PVDF) piezoelectric sensor which is embedded into an aluminum coupon using ultrasonic additive manufacturing (UAM). Traditional manufacturing techniques used to attach smart materials to metals on the surface have drawbacks, including the potential of exposing the sensor to adverse environments or physical degradation during manufacture. UAM can avoid these issues by integrating solid-state metal joining with subtractive processes to enable the fabrication of smart structures. A commercial PVDF sensor is embedded in aluminum with a compression technique to provide frictional coupling between the sensor and the metallic matrix. The PVDF sensor’s frequency bandwidth and impact detection performance are evaluated by conducting cantilever and axial impact tests, as well as harmonic excitation tests with an electrodynamic shaker. Under axial loading, the embedded sensor displays high linearity with a sensitivity of 43.7 mV/N, whereas impact tests in the cantilever configuration exhibit a steady decay rate of 0.13%. Finally, bending tests show good agreement between theoretical and experimental natural frequencies with percentage errors under 6% in two different clamping positions, and correspond to the maximum voltage output obtained from the embedded PVDF sensor at resonance.
