Finite element analysis of the effect of up-armouring on the off-road braking and sharp-turn performance of a high-mobility multi-purpose wheeled vehicle

Abstract

A comprehensive finite element investigation is carried out of the effect of up-armouring on the off-road performance of a prototypical high-mobility multi-purpose wheeled vehicle. The effect of up-armouring on the vehicle performance was investigated under the following off-road manoeuvres: straight-line flat-land braking; straight-line off-angle downhill braking; sharp left turn. In each case, the appropriate vehicle performance criteria are identified and the parameters used to quantify these criteria are defined and assessed. The computational results obtained clearly revealed the compromises in vehicle off-road performance caused by the up-armouring employed to improve vehicle blast and ballistic protection performance and survivability. The results obtained are also analysed and explained in terms of general field-test observations in order to judge the physical soundness and fidelity of the present computational approach. Finally, the potential benefits and ramifications of lightweight up-armouring in providing the needed level of blast and/or ballistic performance while causing fewer compromises in the vehicle off-road performance are also discussed.

Computational investigation of impact energy absorption capability of polyurea coatings via deformation-induced glass transition

“…Within this framework, the aforementioned equations are then solved using a second-order accurate explicit scheme. More details regarding the use of ABAQUS/Explicit in solving transient non-linear dynamics problems can be found in our previous work [23,24].…”

Integration of ANCF continuum-based soil plasticity for off-road vehicle mobility in multibody system dynamics

“…Examples of finite element-based simulation of wheeled terramechanics applications can be found in Grujicic et al (2009), Hambleton andDrescher (2009), Mohsenimanesh et al (2009), Nankali et al (2012, Pruiksma et al (2011), Shoop et al (2006), Xia (2011), and Xia and Yang (2012). For an example of a full vehicle on soft soil refer to Grujicic et al (2009).…”

Design and Comparative Analysis of Connecting Rod using Finite Element Analysis

“…[11] studied the effect of change in materials by carrying out FEA analysis on connecting rod, reduction in the weight of connecting rod was observed by replacing the material from 4340 alloy steel to AlSiC-9 and found that AlSiC-9 is 61.65% lighter compared to 4340 alloy steel connecting rod. In last few decades, many researchers [12][13][14][15][16][17][18] have worked on optimization of automotive vehicle components to enhance the performance characteristics but major emphasis is given on engine components. In current study, the finite element analysis is carried out on the connecting rod to understand the design parameters like stress, strain, deformation etc.…”
