Numerical Simulation Of Moving Vehicle Across the Obstacle

Abstract

Vehicle excitation by passing over pavement unevenness represents the actual problem which is solved on many departments in this time. The numerical methods are mainly applied for the solutions of the interaction of similar systems. The Finite Element Method (FEM) is the best-known and widely used. It provides appropriate accuracy. In this article, commercial computer software ADINA based on the FEM is used to solve kinematic excitation of vehicle. The 2D model of vehicle which represents real type of lorry T-815 is excited by simulation of passage across obstacle. There are compared dynamic responses of the vehicle on the kinematic excitation at different speeds.

The comparisons of computational models of pavement due to the dynamic load act

“…The shape of the obstacle is similar to the shapes that are recommended for the dynamic tests of the bridges. This shape is also identical with retarders on the pavement [3]. (Fig.…”

Mutual Comparison between the Two Computational Models of Interaction System Vehicle-Pavement

“…A discrete model of the vehicle with finite degrees of freedom simplifies the mathematical solution of the problem. This assumption transforms partial differential equations to the ordinary differential equations [3]. The main characteristics of the half-part model are defined by the three diagonal matricesmass {m}, stiffness {k i } and damping {b i } matrices, which contain experimentally measured values [1].…”

The natural frequencies have also been determined: {f} ={f (1) ; f (2) ; f (3) ; f (4) ; f (5) }={1.13;1.45; 8.89; 10.91; 11.71} (Hz).…”
