Blacksburg,VA,USA (Received 17May 2010;?nal version received 11October 2010)This paper provides an overview of the latest advances in road vehicle suspension design,dynamics,and control,together with the authors’perspectives,in the context of vehicle ride,handling,and stability.The general aspects of road vehicle suspension dynamics and design are discussed,followed by descriptions of road-roughness excitations with a particular emphasis on road potholes.Passive suspension system designs and their effects on road vehicle dynamics and stability are presented in terms of in-plane and full-vehicle arrangements.Controlled suspensions are also reviewed and discussed.The paper concludes with some potential research topics,in particular those associated with the development of hybrid and electric vehicles.Keywords:road vehicle suspension system;suspension design;vehicle /suspension dynamics;controlled suspensions;energy ef?ciency Introduction Suspension design has been extensively explored during the past few decades,considerably contributing to the improvement of ride,handling,and safety for road vehicles.One of the primary trends for the next generation of road vehicles is to employ alternative powertrain and

propulsion systems in a hybrid or fully electric manner,in order to offer viable solutions for reducing fossil fuel consumption and meeting the more stringent emission and safety standards.This poses signi?cant challenges for chassis design,layout,and system integration,which thus have also a considerable impact on the vehicle /suspension dynamics and suspension design.In addition,virtual prototyping popularly used in vehicle development also requires advances and deeper insight into the fundamentals of vehicle systems,including vehicle /suspension dynamics and suspension design.

The special issue of Vehicle System Dynamics on ‘Advanced Suspension Systems and Dynamics for Future Road Vehicles’compiles the state-of-art progress of the suspension design,dynamics,and control for addressing the challenges associated with the development *Corresponding author.Email:dongpu@uwaterloo.ca

of next-generation road vehicles.This paper presents the editors’perspectives together with a concise state-of-the-art survey of the available literature on road vehicle suspension design,dynamics,and control.Instead of focusing on a speci?c or multiple classes of vehicles,this paper is primarily concerned with different suspension design arrangements,including roll-plane,pitch-plane,and full-vehicle,and associated vehicle dynamics and stability.The popularly used quarter-car suspension system can be treated as a special case of the roll-plane arrangement assuming identical road inputs and symmetric load distributions on the left and right vehicle wheels.Different classes of road vehicles have different requirements related to each of the in-plane suspension arrangements and thus on the full-vehicle suspension system,which will be re?ected and discussed later in the article.There are generally three fundamental elements for a typical vehicle suspension system,including springing,damping,and location of the wheel.The ?rst two will be the main focus of this article,while the latter related to suspension geometry,kinematics and compliance (K&C),will also be brie?y d2d80e1059eef8c75fbfb3c2pared with a large number of literatures on the suspension springing and damping,there are only very limited research publications on the suspension geometry and K&C and associated vehicle dynamics and stability,whose analyses generally demand a complex and validated vehicle system model and supports from extensive experimental data and /or tests.These factors have hindered the technical publications in this area.As such,a comprehensive technical review and discussion on different types of independent suspension systems for road vehicles is still lacking from the literature.This paper starts with a general discussion on vehicle /suspension dynamics and suspension design and characterisation of road excitations including random road-roughness pro?les and road potholes.The passive in-plane and full-wheel suspension arrangements and their associated properties and dynamics are then discussed and re …… 此处隐藏：39469字，全部文档内容请下载后查看。喜欢就下载吧 ……
