Abstract

The invention discloses a tire mechanical property intelligent detection device and a detection method thereof. The detection device comprises a tire, a rim, a gravity sensor, a camera and a marking point; the gravity sensor and the camera are arranged at the same circumferential position of the rim; the marking point is positioned on the surface of the inner side of the tire; the camera is arranged over against an area of the marking point. The detection method adopts a neural network algorithm; when the working tire is deformed, the camera is utilized to acquire displacement variation of a phosphor dot and a tire force is obtained by the neural network algorithm; a six-component sensor is not required for measuring a tangential force, an axial force, a vertical force, a running torque, a rolling moment and a yawing moment on a rotary drum test bench to realize solution of a longitudinal force, a lateral force, a vertical load, a running torque, a rolling moment and an aligning torque of the tire; the tire mechanical property intelligent detection device has the advantages of being simple and compact in structure, simple and convenient to operate, low in cost and the like.

Description

technical field [0001] The invention relates to the field of measurement of tire mechanical properties, in particular to an intelligent system for measuring tire mechanical properties. Background technique [0002] Most of the existing test systems for vehicle dynamics and dynamic characteristics are based on vehicle chassis dynamometers with auxiliary equipment or integrated drum-based test systems for vehicle dynamics and dynamic characteristics. The improved system composed of an integrated drum, the basic principle is to use the drum to simulate the road surface, put the driving wheel of the car on the drum, drive the drum to rotate, control the resistance to the drum, simulate different driving resistance, and calculate through the sensor Tire force, its mechanism is complicated, and field area is big, and test condition limitation is big, and manufacturing cost is also high shortcoming. Contents of the invention [0003] In order to overcome the deficiencies of th...
