Embodiment Construction
[0012] like image 3 As shown, a coupling lateral force elimination device for a tire stiffness test bench includes a test bench main frame 1, a road surface rotating support 2, a servo motor 3 that can control the lateral movement of the test road surface in real time, a fixed road surface 4 and a moving road surface 5. The road surface rotating support 2 is connected to the main frame 1 of the test bench through bearings, and the servo motor 3 that can control the lateral movement of the test road surface in real time is fixed on the fixed road surface 4 to control the movement of the mobile road surface 5 .
[0013] Working principle of the present invention:
[0014] like figure 1 As shown, the same tire finite element model is used to simulate the roll stiffness, the road surface friction coefficient is set to 1 to simulate the stiffness test bench without the coupling lateral force elimination device, and the road surface friction coefficient is set to 0 to simulate the...

The invention discloses a coupling lateral force eliminating device for a tire rigidity test bed. The coupling lateral force eliminating device comprises a test bed main frame, a road surface rotatingbracket, a servo motor capable of controlling lateral movement of a test road surface in real time, a fixed road surface and a movable road surface, the road surface rotating bracket is connected tothe tire rigidity test bed main frame through a bearing, and a servo motor capable of controlling the test road surface to move laterally in real time is fixed to the fixed pavement end and controls the movable road surface to move. The coupling lateral force eliminating device is simple in structure, the servo motor responds in real time to solve the problem that lateral force changes along withsubsidence, coupling lateral force is eliminated to achieve accurate rigidity testing, the road surface design is ingenious and reasonable, the moving road surface rotates along with the road surfacerotating support, tire roll motion simulation is achieved, and meanwhile it is guaranteed that movement of the road surface does not influence vertical loads.
Description
technical field [0001] The invention relates to the field of tire stiffness testing equipment, in particular to a coupling lateral force elimination device for a tire stiffness test bench. Background technique [0002] The mechanical characteristics of tire stiffness can be used to establish tire models, which is of great significance for vehicle dynamics simulation. The tire stiffness test bench is an important device to obtain the mechanical properties of the tire stiffness. [0003] The six-component force characteristic of the tire has strong coupling, so in the process of tire stiffness test, there are often unexpected forces generated, which will affect the test results. The influence of the coupled lateral force is particularly prominent during the roll stiffness test. The roll stiffness test expects to obtain the relationship between the vertical force and the sinkage, and no other direction force can be used. However, due to the existence of the roll angle, the tir...
