System and method for measuring dynamic stress distribution of tyre of vehicle

Abstract

The invention discloses a system and method for measuring the dynamic stress distribution of a tyre of a vehicle, and the system comprises a plurality of stress distribution measurement devices and anupper monitoring device. Each stress distribution measurement device comprises a stress measurement device, 2N measurement electrodes and a conductive ring disposed on a to-be-measured typre in a peripheral direction, wherein the conductive ring is disposed at the joint of the to-be-measured typre and a wheel hub. The method comprises the steps: 1, transmitting a stress distribution measurement instruction; 2, measuring the stress distribution; 3, synchronously uploading a stress distribution measurement result. The stress distribution measurement devices are distributed on all to-be-measuredtyres, thereby achieving the real-time and accurate measurement of the stress distribution of all tyres of a to-be-measured vehicle. Each to-be-measured tyre is provided with a conductive layer in the peripheral direction, and the 2N measurement electrodes which make contact with the conductive layers are uniformly distributed on the wheel hub in the peripheral direction are used for the measurement of the stress distribution. The system and method can achieve the real-time and accurate measurement of the real stress distribution of the tyres.

Description

technical field [0001] The invention belongs to the technical field of vehicle safety monitoring, and in particular relates to a vehicle tire dynamic stress distribution measurement system and method. Background technique [0002] Automobiles have become one of the indispensable means of transportation for people to travel, and the safety and reliability of vehicles directly determine the safety of people's lives. Automobile tires are the main load-bearing parts of automobiles, and their safety cannot be ignored. At present, the car tire monitoring devices used on the market can only monitor the tire pressure during the driving process of the vehicle, but cannot provide early warning for early defects inside the tire, and cannot reflect the force on the tire during the driving process of the vehicle. The situation, let alone the stress distribution of the tire, the monitored parameters are single, and the use effect is poor, so there are many safety hazards in the driving p...

At present, the car tire monitoring devices used on the market can only monitor the tire pressure during the driving process of the vehicle, but cannot provide early warning for early defects inside the tire, and cannot reflect the force on the tire during the driving process of the vehicle. The situation, let alone the stress distribution of the tire, the monitored parameters are single, and the use effect is poor, so there are many safety hazards in the driving process of the vehicle.
