Basic Research And Structure Design On ABS Dynamic Simulate Test Stand

With the constantly boosting vehicle speed and the increasingly attention to road traffic condition, more and more vehicle have equipped anti-lock braking system, and now the question is how to test the large number of ABS, this is an exigent problem for domestic vehicle test calling.This dissertation designs an ABS test stand on the basis of synthetically researching the work principium of automobile ABS and the road test measures. The test stand can accurately test the performance of ABS. The construction design has adequately considered the condition of domestic vehicle.This dissertation detailedly introduces ABS' theory base, construction and control principle; analyses different test measures, merit and defect of each measure; puts forward the test stand test measure, finished educing the theory, demonstrates the feasibility of ABS' performance test on the test stand; selects the powder clutch as the key component, realizes the dynamical simulation of vehicle brake process controlled by ABS, exhibits the movement relation between wheel and road surface during braking process by the active rotor and driven rotor of torque controller, and this is helpful to test the slippage rate of ABS; put forwarded a set of feasible optimization and combination schemes of assembled flywheel system's moment of inertia and balancing; finished motor selection and its driver; finished the construction and design of ABS test stand.According to the primary survey, there is no domestic production and patent about the test stand we researched, so the test stand designed in this dissertation has definite superiority, it can solve the exigent problem of domestic vehicle test calling. It has important significances for the research of ABS controller, the selection of ABS controller, the vehicle test calling's development and the road traffic safety condition's improvement.
