Multi-body dynamics in full-vehicle handling analysis

Use of “contact” in Multi-body Vehicle Dynamics

This paper reports the first results of a new interface between the multi-body simulation software SIMPACK Rail and Kalker’s wheel-rail contact software CONTACT. The main benefit is in the more accurate distributions of shear stress and micro-slip in the contact area, that together form the primary inputs to wear calculations. Further benefits of the interfacing reside in the ability to perform...

Vibration Analysis Based on Full Multi-Body Model for the Commercial Vehicle Suspension System

Based on the characteristic of a type of commercial vehicle, a multi-body model of its full suspension system with twenty Degree of Freedom (DOF) was established in MSC.ADAMS. After evaluating relative condition parameters such as stiffness and damping index on the simulation model, the effects of outside exciting on the suspension system have been worked out numerically. The harmonic response ...

Multi-Body Integrated Vehicle-Occupant Models for Collision Mitigation and Vehicle Safety using Dynamics Control Systems

Intelligent Vehicle Handling: Steering and Body Postures While Cornering

Vehicle handling and control is an essential aspect of intelligent driver assistance systems, a building block of the upcoming generation of ”smart cars”. A car’s handling is affected by (i) technological (engine, suspension, brakes, tires, wheels, steering, etc.), (ii) environmental (road condition, weather, traffic, etc.), and (iii) human (attentiveness, reactiveness, driver agility, etc.) fa...

Masticatory biomechanics in the rabbit: a multi-body dynamics analysis

Multi-body dynamics is a powerful engineering tool which is becoming increasingly popular for the simulation and analysis of skull biomechanics. This paper presents the first application of multi-body dynamics to analyse the biomechanics of the rabbit skull. A model has been constructed through the combination of manual dissection and three-dimensional imaging techniques (magnetic resonance ima...
