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.

It is studied that a great proportion of traffic problems lies in vehicles’ steering system, and the maximum steering angle decides their steering capability and their minimum turning radius. The measuring principle of rapid measuring system, and the automatic tracking principle of measurement system have been analyzed in the paper. Also, the infrared tracking, the measuring plate positioning, the calculation of minimum turning radius, and the processing method of the test results have been described in detail. It is proved that the automatic automobile steering angle detecting system has reached the general requirements both in detection resolution and the measuring accuracy.

Go-kart is a one of the motor sport which is played globally. This racing does not require any professional drivers or greater speed. It is a light weight and cheaper vehicle which does not require suspension and differential. In this paper we are concentrating on Roll cage and steering system of Go-kart. While keeping it light weight, chassis material is selected as AISI 1018 which give more tensile strength, machinability, and can sustain maximum load. For designing and analysis CATIA and ANSYS soft wares were used. Whereas in steering system the Ackermann steering mechanism is used for attaining maximum cornering speed, without the slippage of tires. This also gives us minimum turning radius, helping us to take sharp turns when the driver has to take sharp corners.

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.

When a larger bus steering in the corners, it easily affected by the lateral acceleration so that the vehicle sideslips or rolls over, using the research methods of combining with real vehicle modeling and simulation to ensure the safety and comfort of the passengers. Analyzed and researched systems that affecting vehicles stability performance, including power train, steering system, brake system and the vehicles road model of the system curve .On this basis, compared to the acceleration values which the motorbus body can withstand in different states, proposing the acceleration values when human feel comfortable, uncomfortable and terrible, then conducted simulation tests under different turning radius and speeds. The results showed that: on the premise of ensuring the safety and comfort of vehicle passengers, the allowable speed limit with different bend radius is not the same; then it drew series of limit speeds allowed by series of bend radius, providing a reference and basis for future road construction and motorbus technical improvement.

AbstractVariable stiffness laminates can be manufactured using curvilinear fiber paths. A curvilinear fiber path is generally defined based on the plate size and has a curvature that is dependent on the plate size. In practice, however, the fiber path must satisfy manufacturing constraints, such as the minimum turning radius imposed by the automated fiber placement machine, thereby limiting the possible amount of fiber steering. In this work, we studied the effect of the plate size on the structural properties of a plate manufactured with curvilinear fibers. We considered four plate sizes, which were designed by a constant curvature fiber path. We optimized the plates for both maximum buckling load and in-plane stiffness. The results showed that the in-plane stiffness of the plate was not controlled by the plate size, whereas the buckling load was highly affected by the curvature of the fiber path. Hence, the potential of a buckling load increase reduced for plate sizes smaller than the minimum turning radius. In addition, for a given maximum curvature of the fiber path, the influence of a complex layup on the buckling load was marginal.

Targeting mountain orchards, which slope from 25 degrees to 45 degrees, the 7YGS-45 type self-propelled dual-track orchard transport was developed. Through designing,optimize the following key parameters such as power consumption、running speed、turning radius and slope angle, and have real operation performance test for dual-track orchard transport. The test shows that the transport’s maximum climbing slope is 47°, minimum turning radius is 8m, and it can satisfy the steady running with the speed of 1.1m/s-1.3m/s and capacity of 300kg. The 7YGS-45 type self-propelled dual-track orchard transport is not only suitable for transporting the fruits and fertilizers in mountain orchards, but also can be equipped with spraying and pruning machines to work.

This paper addresses a particular pursuit-evasion game with two pursuers with slower speed but smaller minimum turning radius and a faster evader with bigger minimum turning radius. This is a game of kind, and what interests us is how to construct the barrier that separates the state zone into capture zone and escape zone, and what the optimal strategies for the players are on the barrier. Under some mild assumptions, we give the explicit form of the barrier near the BUP (i.e., the boundary of the usable part on the boundary of the target set) by using Isaacs’ method, and a procedure to construct the barrier when the retrogressive time is big enough by determining the optimal strategies for the players on the BUP. Then we prove that the optimal strategies remain unchanged near some special parts on the BUP, and we give two examples to illustrate these situations.
