Rail upper end slide-and-guide is provided with a test platform, and test platform upper surface is used for sliding contact and tests tire；Guide rail horizontal
One end is fixed with a high-speed hydraulic jar support, and this high-speed hydraulic jar support is provided with a high speed hydraulic cylinder, horizontal in guide rail
The other end is fixed with a buffering hydraulic jar support, and this buffering hydraulic jar support is provided with a buffering hydraulic cylinder.
And, the top of test tire is vertically-mounted a tire loading hydraulic cylinder, and this tire loading hydraulic cylinder loads pressure
Force direction is perpendicular to test platform.
And, described high speed hydraulic cylinder, test platform and buffering hydraulic cylinder are coaxially disposed.
Advantage of the present utility model and good effect are:
1st, this test platform linear motion, the relative motion between platform and tire is completely the same with takeoff and landing process,
Compared with traditional experiment scheme, the method is high to actual condition reducing degree.
2nd, this test platform adopts high speed hydraulic cylinder as power source, it is to avoid the accelerating travel of distance, and system is permissible
Accelerate to the speed of 100km/h in the accelerating travel of 1m level, can significantly reduce equipment volume.
3rd, this test platform adopts buffering hydraulic cylinder as system buffer damping, platform can be made complete in shorter stroke
Slow down, and buffering course safety and steady.
4th, the tire of this test platform is loaded using loading hydraulic cylinder, and loading force size is adjustable, by adding tire
Damping and suspension, can improve the effectiveness of system emulation further.
5th, the relative motion that this utility model can be when truly simulated aircraft lands between tire and ground, makes test strip
Part is more fitted the real processes of takeoff and landing, can fully meet the needs of all kinds of tyre performances tests.
