Overview of suspension system dynamics analysis

Abstract

The control strategy of vehicle suspension system model has been gradually transferred to the modern control optimization algorithm, and the traditional suspension has gradually been unable to meet the vehicle’s pursuit of high performance. Starting from vehicle modal analysis, the development status of suspension model building method, category and control strategy is described respectively. On this basis, the current development difficulties and trends are analyzed.

Exploring the potential of onboard energy scavenging subsystems for generating valuable data

“…The average power P av generated by the piezoelectric material's vibration is given by (Zhang et al, 2020;Ndoye et al, 2011;Davidson and Mo, 2014;De Fazio et al, 2023). (3)…”

“…Road roughness (that may include corrugations, potholes, asphalt quality, etc. (Abulizi et al, 2016) health of vehicle suspension system (that may include springs, shock absorbers, and struts, etc., (Zhang et al, 2020), driving styles (that may include reckless, anxious style, and careful, etc., (Peng et al, 2022), all affect onboard energy scavenging. The motivation behind this work is to use piezo material not primarily to scavenge electrical energy for powering meso-to-micro scale devices but also to expose and utilize the information concealed in energy creation patterns.…”

“…There are several limitations of previous studies on energy harvesting using piezoelectric materials, such as some studies focused solely on energy generation without fully exploring the potential for valuable data collection and utilization (Yaqub et al, 2012;Chukwu and Mahajan, 2017). Previous research is confined to specific applications (Abulizi et al, 2016;Zhang et al, 2020), overlooking the broader spectrum of possibilities for onboard energy scavenging subsystems. Most of the prior art primarily adopted theoretical and simulation approaches, lacking practical implementations or realworld testing (Chukwu and Mahajan, 2017;Rode et al, 2023;Jazar, 2017).…”

A Review on Various Control Strategies and Algorithms in Vehicle Suspension Systems

“…The ride performance limitation, high cost, and other complexities associated with active suspension systems are overcome using semi-active suspension systems [11]. Control algorithms, semi-active dampers, accelerators, and ride height sensors are the main parts of semi-active suspension systems.…”
