Tire hydroplaning performance dynamic test experiment table and experiment method

Abstract

The invention provides a tire hydroplaning performance dynamic test experiment table and experiment method, and belongs to the field of tire mechanical property test. The experiment table comprises a base table which is provided with a combined framework, a tire contact disc, a camera and data and image acquisition equipment. The combined framework is provided with a motor and a pressurization water container. The pressurization water container is provided with a water film ejector. The tire contact disc is arranged below a tested tire. The camera is arranged exactly below the contact position of the tested tire and the tire contact disc. The data and image acquisition equipment and the camera are connected via a data line. The experiment method comprises performance tests of the tested tire under the normal state and the side inclination and side deflection states and the state of combination of side inclination and side deflection. Various working conditions of the tire in high-speed operation on dry and wet pavements under the vertical or side inclination state can be simulated, and the tire hydroplaning performance dynamic test experiment table and experiment method are used for testing the mechanical property of the tire so that improved experiment data can be provided for research and development and performance analysis of the tire.

Description

technical field [0001] The invention relates to the field of tire mechanical performance testing, in particular to a tire water skid performance dynamic testing test bench and an experimental method, which are suitable for testing the interaction characteristics between tires and road surfaces. Background technique [0002] The safe running of a car on the road depends on the contact between the tire and the road surface. In wet weather or after rain, when the vehicle is driving at high speed on a slippery road surface, the tires will slip due to the dynamic lubrication of the fluid on the road surface. The so-called water skid refers to the phenomenon that when there is water on the road surface, the wheels of the high-speed vehicle will float and slip out of control due to the action of the water film. At this time, the vehicle is easy to lose the steering control and deceleration braking , resulting in a car accident. [0003] At present, most of the performance experime...

Problems solved by technology

[0004] There are still some disadvantages in the field experiment method: first, the disassembly and assembly of the tested tires is more troublesome, and the repeatability of the experiment is poor; It is only to judge whether the tire tread is on the ground, and there is a deficiency that more detailed tests cannot be carried out
