Embodiment 1

[0023] see figure 1 , the angle-adjustable slope for evaluating the performance of the lunar vehicle of the present invention includes a gantry 6, a slope body 10, a reference plate 3 and a driving device, the slope body 10 includes a main body 8 and several load-bearing beams 4, and the load-bearing beams 4 are fixedly arranged At the bottom of the main board body 8, a number of side plates 9 are connected to the main board body 8 to form a box with an open top, one end of the load-bearing beam 4 is connected with the driving device through a connecting piece, and the reference plate 3 is arranged on a horizontal plane, and one end thereof It is fixedly connected with the lower end of the side plate of the gantry frame 6, and the other end is hinged with the main board body 8. The driving device is arranged on the gantry frame 6. The driving device is connected with one end of the load-bearing beam 4, and the driving device can drive the end of the load-bearing beam 4 to move ...

Embodiment 2

[0027] The angle-adjustable slope for evaluating the performance of the lunar vehicle of the present invention includes a gantry frame, a slope body and a driving device, the driving device is arranged on the gantry frame, the driving device is connected with one end of the slope body, and the driving device can drive the slope body The end moves up and down to adjust the slope of the ramp body. The angle-adjustable slope of the present invention can build a slope with any slope value between 5°-45°. The slope body can be rotated, and slopes with different slope values ​​can be constructed by rotating the slope body, which is convenient for operation and testing. There is no need to carry out a series of work such as lifting the lunar rover, reconstructing the attitude of the lunar rover, and there is no need to carry out dust protection for hydraulic equipment such as rotating devices or motor equipment, and the structure is simple and the cost is low.

Abstract

The invention provides an angle-adjustable slope used for assessing the performance of lunar rovers, comprising a portal frame, a slope body, a reference flat plate and a driving device. The slope body includes a main plate body and a plurality of bearing beams fixedly arranged at the bottom of the main plate body. One end of each bearing beam is connected with the driving device through a connector. One end of the reference flat plate is fixedly connected with the lower ends of the side plates of the portal frame, and the other end is hinged with the main plate body. The driving device is arranged on the portable frame, is connected with one end of each bearing beam, and can drive the end of each bearing beam to move up and down to adjust the slope degree of the main plate body, wherein the slope degree is 5-45 degrees. Compared with the prior art, according to the angle-adjustable slope, a slope of any value of slope between 5 degrees and 45 degrees can be constructed, slopes of different values of slope can be constructed by rotating the slope body, operation and test are facilitated, a series of work such as lunar rover lifting and lunar rover attitude reconfiguration is not needed before each test, and the angle-adjustable slope is simple in structure and low in cost.

Description

technical field [0001] The invention relates to a device for evaluating a lunar rover, in particular to an angle-adjustable slope for evaluating the performance of a lunar rover. Background technique [0002] The angle-adjustable slope is mainly used for the assessment of the extreme ability of the lunar rover, and for the assessment of the extreme slope adaptability of the lunar rover, the obstacle limit ability under a certain slope, and the maximum slope adaptability under a certain obstacle. Due to the different types of simulated lunar soil, the ultimate capabilities of the lunar rover are different under different simulated media and different working conditions. To accurately and quickly construct the corresponding terrain for assessment, special equipment and devices are required. At present, there are mainly two kinds of angle-adjustable slopes, one is an improved version of the fixed slope, that is, the slope supports are selected to have different step heights, bu...
