STUDIES OF OFF-ROAD VEHICLES IN THE RIVERINE ENVIRONMENT. VOLUME II. ANALYTICAL METHOD FOR EGRESS EVALUATION

Abstract

A limited computer-simulation model describing the dynamics of a swimming vehicle egressing from a stream is formulated. The effects of soil reactions, hydrostatic forces, suspension and tire dynamics, and auxiliary egress assist forces are considered. Results of a parametric study are presented for a four-wheeled, box-shaped vehicle egressing onto a hard, uniformly sloped bank. Length, freeboard, center of gravity, suspension spring and damping rates, initial velocity, and bank coefficient are varied in the analysis. A correlation study, which validates the computer simulation model, is also described. Plots of normal wheel-loading versus distance up the bank, showing a comparison between the computer simulation and scale-model tests, are included. Recommendations for a comprehensive parametric study and a correlation study with full-scale vehicles are made.
