The telescopic member 12 is connected to the base 11 and is capable of swinging along a longitudinal sector of the base 11, and the angle gauge 13 is used to indicate the angle formed between the telescopic member 12 and the base 11.
Referring to fig. 2 to 5, the telescopic member 12 includes a cylinder 121, a piston rod 122, a flange 123 and a height sensor 124, wherein one end of the flange 123 is connected to the piston rod 122, and the other end is fixedly connected to a hub of an automobile. One end of the piston rod 122 extends into the cylinder 121, and the pressure in the cylinder 121 can drive the piston rod 122 to move up and down relative to the cylinder 121. The cylinder 121 is connected to the base 11 by the rotation pin 112 such that the cylinder 121 can be longitudinally fanned about the central axis of the rotation pin 112 (as shown in fig. 4). The angle gauge 13 includes a scale plate 131 and a pointer 132, the scale plate 131 is fixed on the base 11 and is perpendicular to the upper surface of the base 11, and the pointer 132 is fixed on the cylinder 121 and can swing along with the cylinder 121 (as shown in fig. 5). The scale plate 131 is marked with a scale for indicating the angle, and the front end of the pointer 132 points to the scale on the scale plate 131.
When the pointer 132 swings with the cylinder 121, the pointer 132 points to different scales on the scale plate 131, and the indicated scales are included angles between the supporting device 10 and the horizontal plane. The supporting device 10 is fixedly connected with the automobile hub disk to simulate an automobile tire, and the camber angle of the tire in the whole automobile chassis test can be recorded by recording the scales of the angle meter 13. In other embodiments, the angle gauge 13 may also be connected to the control device 20, where the angle gauge 13 transmits the angle data to the control device 20 after the analog-to-digital conversion, and the control device 20 may record and output the tire camber angle data.
According to the vehicle working condition simulation system, the telescopic piece 12 can swing longitudinally along the base 11, and the vehicle working condition simulation system is different from the traditional fixed tire support auxiliary detection and more accords with the actual working condition. The tire inclination angle is detected in real time through the angle gauge 13, so that the chassis attitude measurement is more convenient, visual and accurate.
As shown in fig. 6, the height sensor 124 includes a static slide 1241 and a moving slide 1242, the static slide 1241 is fixed on the cylinder 121, the moving slide 1242 is fixed on the piston rod 122 and can move up and down along with the piston rod 122, and the front end of the moving slide 1242 is in sliding contact with the static slide 1241.

The height represented by the different electrical signals is preset in the control device 20, i.e. the height of the support device 10, i.e. the radius of the tire simulated by the support device 10, can be measured by the height sensor 124.
The cylinder 121 is provided with a connecting hole 1211, the connecting hole 1211 is connected with the control device 20, and the control device 20 can control the pressure in the cylinder 121 through the connecting hole 1211 so that the piston rod 122 can move up and down relative to the cylinder 121. In the present embodiment, the telescopic member 12 is a telescopic cylinder, the piston rod 122 is pneumatically driven in the cylinder 121, and in other embodiments, the telescopic member 12 may be a hydraulic cylinder or other lifting mechanism.
As shown in fig. 7, the control device 20 includes a programmable controller (PLC) 21, a pressurizing pump 22, and a pressure release valve 23, and the pressurizing pump 22 and the pressure release valve 23 are connected to the programmable controller 21 and the connection hole 1211. The programmable controller 21 increases the pressure in the cylinder 121 through the pressure pump 22 to enable the piston rod 122 to move upwards relative to the cylinder 121 so as to lift the height of the supporting device 10, and the programmable controller 21 decreases the pressure in the cylinder 121 through the pressure release valve 23 to enable the piston rod 122 to move downwards relative to the cylinder 121 so as to reduce the height of the supporting device 10.
The programmable controller 21 is connected with the load sensor 111 and the height sensor 124, and the load data of the supporting device 10 collected by the load sensor 111 and the height data of the supporting device 10 collected by the height sensor 124 are transmitted to the programmable controller 21. The programmable controller 21 includes a tire load-tire radius correspondence, and the corresponding tire radius can be obtained by inputting the tire load, that is, the load sensor 111 inputs load data, and the corresponding tire radius can be calculated from the tire load-tire radius correspondence. The programmable controller 21 compares the corresponding tire radius with the height data inputted from the height sensor 124, and then changes the height of the supporting device 10 through the booster pump 22 and the relief valve 23.
In the present embodiment, the tire load-tire radius correspondence is a linear equation, the coordinate system is shown in fig. 8, the abscissa x represents the tire load (Kg), and the ordinate y represents the tire radius (mm). In fig. 8, the equation of tire load versus tire radius for a tire of a certain model is y= -0.04x+362.4.
The programmable controller 21 may include a plurality of sets of tire load-tire radius equations to correspond to different types of tires, and in the whole vehicle chassis test, the corresponding tire load-tire radius equations may be selected according to actual requirements. The programmable controller 21 is also provided with a man-machine interaction module (not shown) for inputting new tire load-tire radius equations and modifying existing tire load-tire radius equations.
According to the vehicle working condition simulation system provided by the embodiment, the support device 10 is used for simulating the substituted tire, the suspension is not blocked in measurement, and the suspension data can be directly measured without frequently disassembling and assembling the tire. The height of the support device 10 can be adjusted directly according to the vehicle load by the built-in programmable controller 21 of the tire load-tire radius correspondence, so as to simulate tires with different radii.
The embodiment also provides an application method of the vehicle working condition simulation system, which is applied to the vehicle working condition simulation system, and comprises steps S1 to S3. Step S1 is to connect the hub plate of the automobile with the flange plate 123, and simulate a tire by the supporting device 10.
Step S2 includes steps S21 and S22, where step S21 is that the programmable controller 21 collects load data and height data of the supporting device 10 through the load sensor 111 and the height sensor 124, and substitutes the load data into a tire load-tire radius correspondence to obtain a corresponding tire radius.
Step S22 is that the programmable controller 21 compares the height data input by the corresponding tire radius and the height sensor 124, and when the height data is smaller than the corresponding tire radius, the programmable controller 21 increases the pressure in the cylinder 121 by the booster pump 22, so that the piston rod 122 moves upward relative to the cylinder 121, and further the height of the supporting device 10 is raised until the height data is equal to the corresponding tire radius. When the height data is greater than the corresponding tire radius, the programmable controller 21 reduces the pressure in the cylinder 121 via the pressure relief valve 23, causing the piston rod 122 to move downward relative to the cylinder 121, thereby lowering the height of the support apparatus 10 until the height data is equal to the corresponding tire radius.
Step S3 is to record the data of the angle meter 13 and the data of the automobile suspension.
According to the vehicle working condition simulation system and the application method, the support device 10 is used for simulating the substituted tire, the suspension is not blocked in measurement, and the suspension data can be directly measured without frequently dismounting the tire. The height of the support device 10 can be adjusted directly according to the vehicle load by the built-in programmable controller 21 of the tire load-tire radius correspondence, so as to simulate tires with different radii. The telescopic part 12 can swing longitudinally along the base 11, and is different from the traditional fixed tire support auxiliary detection, and better accords with the actual working condition. The tire inclination angle is detected in real time through the angle gauge 13, so that the chassis attitude measurement is more convenient, visual and accurate.
