Embodiment Construction
[0021] The present invention will be further elaborated below in conjunction with the accompanying drawings.
[0022] refer to figure 1 Shown, one embodiment of the present invention is a kind of three-dimensional force sensor that is used for automobile rear axle test system, and in this embodiment, three-dimensional force sensor should comprise the stressed part 1 of elastic body structure, middle part 3 and fixed part 6. The stressed part 1 is placed above the middle part 3, the fixed part 6 is placed under the middle part 3, and the middle part of the middle part 3 is provided with a transverse through hole 4, and the middle part 3 and the fixed There is also a terminal block 7 between the parts 6, and a plurality of strain gauges are attached to the terminal block 7 and the middle part 3. The multiple strain gauges are divided into at least three groups, and each group forms a Wheatstone bridge. It is used to measure the force in the directions of X-axis, Y-axis and Z-ax...

The invention discloses a three-dimensional force sensor used for an automobile rear axle test system and belongs to a force sensor. The three-dimensional force sensor comprises a stress part, a middle part and a fixing part, wherein the stress part, the middle part and the fixing part are of an elastomeric structure. The stress part is arranged above the middle part, the fixing part is arranged below the middle part, and a transverse through hole is formed nearby the middle of the middle part. A wire holder is further arranged between the middle part and the fixing part, and a plurality of strain foils are evenly attached to the middle of the wire holder. Due to the fact that the transverse through hole is additionally formed in middle part of the elastomeric structure, precision of measuring three-dimensional force of the sensor is effectively improved, and the problem of coupling among dimensions of a multi-dimension force sensor is solved. In combination with step structures designed on the upper portion and the lower portion of the middle part, the coupling among the dimensions is further reduced, force in the X-axis direction, the Y-axis direction and the Z-axis direction is measured depending on the three sets of strain foils, no moving part is arranged on the sensor, and therefore sensitivity is high, measuring is accurate and inherent frequency is high.
Description
technical field [0001] The present invention relates to a force sensor, and more specifically, the present invention mainly relates to a three-dimensional force sensor used in an automobile rear axle testing system. Background technique [0002] With the development of science and technology, three-dimensional force sensors have been used in all walks of life. In 1996, Shanghai Second Medical University used a three-dimensional force measuring platform to measure the three-dimensional walking foot-ground contact force of six patients with femoral head necrosis before and after surgery. and compare with normal people. A three-dimensional force sensor is made by using a foil resistance strain gauge pasted on a metal elastic body. Four such sensors are used to support the force plate at the four corners respectively, together with the dynamic strain gauge and the data acquisition card, the whole experimental test system is formed. In 2002, Sun Lining of Hefei Institute of Int...
