Steering system directly determines the tractor steering characteristics. It has great influence on the driving comfort of a tractor and the life of the tire, etc. Based on the platform of the virtual prototype software ADAMS, the virtual prototype model of tractor steering system and the motion simulation were established. The parameters such as the tractor steering angle displacement were measured and the steering performance of tractor was analyzed. The model and simulation method this article used has significant references on the performance analysis of other vehicle steering system.

Two Degree Of Freedom

Based on the two degree of freedom model of kiloton all-terrain crane, he effects of relationship of deflection angle on turning radius were investigated in multi-axle steering system. MATLAB/Simulink was used to analyze the relationship of every axle in multi-axle steering and optimize the minimum turning radius. The studies show that the kiloton all-terrain crane adapted all-wheel steering driving at 5speed , and the front wheel angle was 32.3°, as compared to the rolling radius before optimization, the turning radius in all wheel turnaround reduced by 33%, which improved the vehicle capacity through the complex curve and increased the vehicle steering flexibility.

The Impact

In this paper, a frontal crash analysis is carried out with a full vehicle model in order to investigate the influence of stamping effects of auto-body members on the crash characteristics of the vehicle. Stamping effects are considered for load carrying members such as the front side member and the rear lower. From the analysis result considering stamping effects, it is conformed that stamping history has to be considered for longitudinal members simultaneously that transfer the impact load under the frontal impact. Comparison of simulation result with experimental one also shows that the prediction accuracy of the crash analysis is remarkably improved.

Abstract Efficient navigation of an autonomous mobile robot through a well-defined environment requires the ability of the robot to plan paths. An efficient and reliable planar off-line path planner has been developed that is based on the A* search method. Using this method, two types of planning are accomplished. The first uses a map of all known obstacles to determine the shortest-distance path from a start to goal configuration. The second determines the shortest path along a network of predefined roads. For the most complicated environment of obstacles and roads, a near-optimal piecewise-linear path is found within a few seconds. The planner can generate paths for robots capable of rotation about a point as well as car-like robots that have a minimum turning radius. For car-like robots, the planner can generate forward and reverse paths. This software is currently implemented on a computer controlled Kawasaki Mule 500 all-terrain vehicle and a computer controlled John Deere 690 excavator.
