“…However, the ratios between mass and inertia properties for most conventional passenger vehicles are remarkably similar. This fact has been noted by several studies, including Brennan's study of non-dimensional vehicle dynamics [3], and Allen's investigation of inertial properties [1], which uses the NHTSA inertial parameter database [5].…”

With the rise of efficient powertrain technologies, future vehicles may exhibit a large variance in mass distribution and inertial parameters. This paper asserts the importance of understanding the effects of atypical inertial properties on vehicle handling and driver experience. Atypically low moments of inertia result in changes to the driver's perception of the lateral acceleration, and the transient development of rear tire force. Both effects can be understood conceptually through an analysis of the center of rotation, and are illustrated experimentally in a comparison of data from two vehicles: a production vehicle with typical mass and inertia properties, and a by-wire electric research vehicle with significantly different properties. The information provided in this paper can be used in the future as a new design tool when considering vehicle mass properties.

To be able to analyze the dynamic features comprehensively and more fully in both the lateral and vertical cases for a threewheeled motorbike (TWM), which have been designed and manufactured by the same group of authors and based on to conduct design improvements, the planar vehicle dynamic model (single track) with 03 degrees of freedom (03-DOF) & the vertical dynamic model with 06 degrees of freedom (06-DOF) have been employed. The parameters used in the calculations are based on existing designs from realistic models manufactured through the combination of experimental measurements and theoretical calculation methods empirically. The lateral dynamic calculated results were based on to investigate the dynamic stability when cornering or steering of a 03-wheeled motorbike. In addition, dynamic calculated results were analyzed also in the frequency domain and basec on to help improve the design featurers with more comfortable and safer.

A knowledge of the inertia tensors and centre of gravity locations of rigid bodies and rigid mechanical systems is required in precise control of motion and in many other applications whenever the dynamics of them is significantly determined by these inertia parameters. This paper presents a new method for identifying the inertia tensor and coordinates of the centre of mass of a rigid body or of a rigid mechanical system. The proposed method is based on the work-energy principle and provides high accuracy of identification even on devices with essential dissipation. The tensor and centre of gravity location are defined on a single spherical motion -symmetric precession. The paper gives a survey of existing inertia parameter identification methods, the theoretical fundamentals of the proposed identification method, the hybrid identification device and data processing procedure with error estimation on dissipative systems using proposed and classical methods.
