Researsh About Mechanics Characteristic Of Pedrail-based Side-silp Tester

Along with the rapid increase of automobiles, cars are gradually entering the every family, therefore, the strengthening of the car's various systems and assembly of test theory and test technology research, ensuring in the process of moving cars in good condition, to improve the safety of great importance.This paper is to study steering wheel skidding related issues. First, the study steering wheel and road surface contact mechanics model based on the analyzed when the steering wheel sideslip force and deformation, tilt wheel and built the front toe of the lateral force corresponding changes formula, also shimmy phenomena are briefly described, in the presence of lateral force, the front wheel involved as a damping system simplifies the model and the correlation analysis; Secondly, in the software environment to a pair of front steering wheels as the research object, in the finite element software of tire and road contact model, discuss the positioning parameters, pressure, load and other factors on the impact of lateral force, and to verify that Extraversion and correspond to the side of the anterior bundle relation to the force, and to analyze the reasons for the error; again, according to knowledge of mechanical design in order to track the reciprocating motion for the prototype instrument for a new chain of mechanical design skid plate, to overcome the lack of old-fashioned instrument sideslip, while increasing detection accuracy, and further also described a new skid detection principle and instrument performance, and finally the design of the entire system to sum up the process.In the last of this thesis, on vehicle testing technology development has been prospected: Auto-vehicle detection technology will become mainstream technology for future vehicle inspection, the car is moving the process by its own skid detection system constantly detects and automatically adjust its various parameters, the various parts of the vehicle is always in a good matching condition.The main core of the whole working process is the mechanical model, vehicle skid instrument virtual design and analysis of the core, the initial implementation of the finite element method simulation analysis of tire ground characteristics, which can intuitively speculate the partial tire wear.
