Embodiment Construction
[0012] The wheel pressure measurement device of the lunar surface patrol that eliminates the lateral error of the measurement wheel pressure measurement of the present invention will be further described below in conjunction with the accompanying drawings.
[0013] see figure 2 , figure 2 It is a structural schematic diagram of the wheel pressure measurement device of the lunar surface patrol that eliminates the lateral error of the measurement wheel pressure measurement of the present invention, wherein the main structure of the wheel pressure measurement device of the present invention is the same as the structure of the wheel pressure measurement device disclosed in Chinese patent 201310233749.6 , which includes a wheel pressure table. The wheel pressure table is composed of six groups of identical, liftable wheel pressure measurement units for measuring vertical pressure. Each wheel pressure measurement unit is composed of a lifting unit, a pressure sensor and a wheel sl...

The invention discloses a lunar rover wheel pressure measurement device for eliminating the lateral error of wheel pressure measurement. A wheel pressure platform is composed of six identical liftable wheel pressure measurement units measuring the pressure in the vertical direction. Each wheel pressure measurement unit is composed of a lifting unit, a pressure sensor and a wheel sliding platform. The wheel pressure platform corresponds to the six wheels to be detected of a lunar rover, and the wheel pressure platform can be located at different heights through electrical control and simulate the state of the wheels on a flat land and fluctuation along with terrain and obstacle crossing state of the wheel. The wheel sliding platforms is replaced by a soil groove filled with simulating lunar soil, and the wheels to be detected presses the simulating lunar soil work face of the soil grooves for wheel pressure measurement. Compared with the prior art, the lunar rover wheel pressure measurement device can eliminate the lateral errors in the wheel pressure measurement process, so that when pressure measurement equipment simulates the working conditions of various terrains, the basis pressure of each wheel is similar to the actual use condition of the wheel.
Description
technical field [0001] The invention belongs to the technical field of wheel force measurement of a lunar surface patrol device, and in particular relates to a wheel pressure measurement device for eliminating lateral errors in wheel pressure measurement. Background technique [0002] Chinese patent 201310233749.6 discloses a lunar surface patrol wheel pressure measurement unit and the measuring device composed of the unit. The document discloses that the lunar surface patrol wheel pressure measurement unit can eliminate the influence of horizontal friction on the wheel force and accurately measure The wheel force value of the patroller. The wheel pressure table of the measuring device is composed of six groups of identical wheel pressure measurement units that can be lifted and measured to measure vertical pressure. Each measurement unit is composed of a lifting unit, a pressure sensor and a wheel slide table. A set of liftable electronic scales corresponds to the six whee...
