Research On The Articulated Mechanism Of Articulated Vehicles

Since the research project currently articulated steering the vehicle design and manufacturing lags behind other countries, and therefore articulated vehicle related features in-depth study has important practical significance.For this reason many new articulated vehicle hinge mechanism emerging, articulated roller is one of them. Since the hinge mechanism has a small turning radius, adaptable, and good overall comfort, tire even by force and other notable features, it is recognized as the current development trend of engineering vehicles. So by comparison with the level of three rollers hinge mechanism with other types of roller model the same roads, the vehicle weight distribution; the center of rotation in the middle of the hinge mechanism, by cornering balance control arm adjustment, reduced by half push angle, basic high stability when the three articulated roller hinge point at the center axis of the front and rear wheels, front and rear wheels turning radius R is equal and has a minimum value of the vehicle steering or straight; and in the safe area operations; good steering performance.The main content of the paper work done, investigation and analysis including domestic articulated roller hinge mechanism analysis of its strengths and weaknesses through the line to select the optimal hinge mechanism, while the calculation of their freedom. Kinematics model of the turning radius, climbing obstacle capability, roll stability analysis.Using 3D engineering software for three nodes and ordinary pin articulated articulated roller compactor, the traveling speed and steering angle constant changes in working conditions for motion simulation curve shows three nodes articulated roller is more stable; the steering angle the case of constant travel speed changes, the simulation curve shows three nodes on both sides of the tire roller articulated even by force, the force less volatile and difficult to tipping; obstacle conditions in a single round, three-point articulated hinge roller cab unstressed round obstacle effect, with better comfort.For the following three conditions, the three-point articulated hinge roller hinge mechanism finite element analysis: turning conditions in place, through three-dimensional engineering software to analyze results after stent suffered torque curve; the torque applied to the sides of the fuel tank hinge seat at the post-stent strength check, and optimize. In climbing conditions, is calculated by the maximum traction in climbing angle is 55 ° when applying traction to the front bracket finite element analysis; through the front bracket after treatment,respectively, the balance link and the rear bracket limited element Analysis. In a single round obstacle condition, three-dimensional engineering software analysis, the measured reactionforce suffered three ball joints and reaction are applied to balance the rod, the front bracket and rear bracket on the three structures finite element results of the analysis show compliance with the design requirements.
