Embodiment Construction

[0027] The structure of the present invention will be further described in detail below in conjunction with the embodiments described in the accompanying drawings.

[0028] The measurement of the three-dimensional force and moment is obtained by the combination measurement of eight shear beam sensor mechanisms with different installation methods, which can reduce the displacement gap and local stress caused by different directions of force, and eliminate the lateral (X direction) or longitudinal (Y direction) force on the Z-axis direction force.

[0029] refer to figure 1 , 2 , a combined three-dimensional force and moment testing integrated device, mainly composed of a transverse (X direction) force sensor mechanism C, a vertical (Z direction) force sensor mechanism D, and a longitudinal (Y direction) force sensor mechanism E , Tilt-limiting bolt mechanism F, tilting moment measuring mechanism G and other supporting components. The measurement of three-dimensional force an...

Abstract

The invention relates to railway vehicle bogie parameter detection equipment; aiming at the technical status that dynamic performance can not be fully and accurately evaluated in the existing railway vehicle bogie parameter detection, the invention provides a combined three-dimensional force and moment test board integrated device; the device comprises a horizontal force-testing sensor (C) and a longitudinal force-testing sensor (E) which are respectively composed of two shear beam sensors (16) and a supporting part, and each two shear beam sensors (16) are respectively arranged on a bearing board symmetrically along the X and Y directions by a supporting part I; four shear beam sensors (16) which are vertical to a force-testing sensor mechanism (D) are respectively arranged at the four comers of the bearing board along the Z direction by a supporting part II, and an overturning moment testing mechanism (G) and an anti-overturning bolt mechanism (F) are arranged on the bearing board; the bearing board comprises a bearing cover board (A) and a bearing bottom plate (B) which are connected into one body by the anti-overturning bolt mechanism (F).

Description

technical field [0001] The invention relates to rail vehicle bogie parameter detection equipment, in particular to a combined three-dimensional force and moment testing integrated device. Background technique [0002] Foreign scholars have done a lot of research on three-dimensional force and torque sensors. For example, Kerr, Nguyen, and Ferraresi proposed and studied three-dimensional force sensors with a Stewart structure, but their structures are complex and their linearity is not good. There are also some scholars in China who study three-dimensional force sensors, and have a number of related patent technologies, such as: six degrees of freedom force and moment sensor (Chinese patent: CNZ165435Y), integral pretension platform type three-dimensional force sensor (Chinese patent: CN1263259A), robot Three-dimensional force and moment sensor (Chinese patent: CN2066134U), a kind of three-dimensional force and moment sensor with elastic hinge (patent application number: 9910...
