Problems solved by technology

This kind of pavement is characterized by high mechanical strength, good board performance, and good durability, but the disadvantages are also obvious. Once this simulated pavement is damaged, it is not easy to repair. At the same time, there are seams between the boards and the rubber material of the tires on the pavement after long-term use Adhesion on the surface will lead to uneven friction coefficient of the simulated road surface, which will affect the test results
[0004] The second is the patterned steel plate pavement, which is wear-resistant, but wears more on the test tires.
However, the friction coefficient of this road surface is usually relatively high, and it is difficult to simulate a low friction coefficient. The obvious disadvantage of this road surface is that the number of recycling times is small and the test cost is high.

Embodiment 1

[0032] Such as figure 1 , 2 3. As shown in 3: Trial-manufacture three steel plate simulation pavements with a length of 1100mm and a width of 500mm to be used as the matrix of the composite simulated pavement. The complete simulated pavement is formed by splicing several fixed-length steel plate pavements. Grooves in both transverse and longitudinal directions are processed on three flat steel plates, and the grooves are parallel to each other and form bosses. The width of the groove is determined to be 6 mm, the depth is 8 mm, and the interval between the grooves is determined to be 5 mm. At the same time, the edges with a width of 50mm can be reserved on both sides of the simulated road surface of the steel plate without processing grooves. In the unprocessed area, the single pavement is divided into five equal parts, and three connection holes are processed at the two ends and the middle point to simulate the connection between the pavement and the test bench. Acco...

[0034] Such as Figure 4 , 5 Shown: Trial-manufacture three 1100mm long and 500mm wide steel plate simulated pavements as the matrix of the composite simulated pavement, and the complete simulated pavement is formed by splicing several fixed-length steel plate pavements. Grooves at 60° to the direction of the road surface are processed on three flat steel plates, and the grooves are parallel to each other and form bosses. The width of the groove is determined to be 6 mm, the depth is 10 mm, and the interval between the grooves is determined to be 6 mm. At the same time, the edges with a width of 50mm can be reserved on both sides of the simulated road surface of the steel plate without processing grooves. In the unprocessed area, the single pavement is divided into five equal parts, and three connection holes are processed at the two ends and the middle point to simulate the connection between the pavement and the test bench. According to the test requirements of tire...

Embodiment 3

[0036] Such as Figure 6Shown: Four steel plate substrates with a length of 1100mm and a width of 500m are trial-manufactured, and grooves in the transverse and vertical directions are processed on the four steel plates, and the width of the grooves processed on two steel plates is determined to be 4mm, and the depth is 10mm, the grooves are parallel to each other, and the distance between them is 5mm. The width of the processed grooves on the other two steel plates is determined to be 8mm, and the depth is 10mm. The grooves are parallel to each other, and the interval between them is 5mm. When the steel plate simulates the road surface, an edge with a width of 50 mm can be reserved without processing grooves. In the unprocessed area, the single pavement is divided into five equal parts, and three connection holes are processed at the two ends and the middle point to simulate the connection between the pavement and the test bench. According to the test requirements of tire m...

Abstract

The invention belongs to the technical field of test of mechanical characteristics of a vehicle tire, and in particular relates to a special composite analog pavement for testing mechanical characteristics of a tire, which is used in mechanical test of a tire. The composite pavement comprises a steel plate matrix, a groove and a boss which are machined on the steel plate matrix, and a mixture layer of resin and carborundum which is filled in the groove. The special composite analog pavement overcomes various disadvantages of the current analog pavement for tire test, and has the advantages of high tire test accuracy, high cycle frequency, small external interference and controllable friction coefficient.

Description

technical field [0001] The invention belongs to the technical field of vehicle tire mechanical characteristic testing, and in particular relates to a simulated road surface required for tire mechanical testing. Background technique [0002] With the increasing attention to the safety of vehicles, safety has become a key technical field of vehicles. The core part of the vehicle dynamics is tire mechanics, which drives researchers to design a more concise and efficient tire test bench. The simulated road surface is an important part of the test bench. The simulated road surface with controllable and stable friction coefficient Accurate measurement of tire mechanical properties is crucial. At present, there are mainly three types of simulated road surfaces used in domestic and foreign automobile tire tests: [0003] The first type is a simulated road surface for the test bench made with reference to the material ratio of the actual road surface, such as cement pavement, terra...
