| Popis: | Design and simulation of the chassis of any automobile for validation against crash and consequences is the dire need of designers in the automobile industry today. This paper presents a detailed methodology in this direction and conclusions drawn might be obliging by the basic constraints and loading conditions of the real time situations. The paper describes detailed analysis and loads of the considered roll cage model. In the current study importance is given for critical points for bent sections-using two elements which has shown better results than the one with single element discretization as in the previous literatures. The design considerations include several aspects of driver ergonomics, suspension geometry, vehicle dynamics, dynamic load transfer, roll centre variations and centre of gravity positions in dynamic modes, i.e., studying the anti-dive and anti-squat concepts keenly. The following sections of the paper detail the selection criteria and factors considered in the process. The chassis is deliberately tested for its behaviour in static and impact loading, drop and heave conditions. The results are further compared with the standards and experimental values obtained in the previous literatures and annotations. |
