Embodiment Construction

[0045] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0046] The present embodiment specifically describes the application of the present invention in detail for the front bracket part 5 of a heavy goods vehicle. As shown in Figure 3, the front bracket part 5 is a linear cantilever beam, and in the heavy goods vehicle, through the bolt hole 28 and the positioning hole 22 are connected to the side of the vehicle body, through the application of the present invention, reflecting the main concern load 24 acting vertically through the positioning hole 22 without being affected by the disturbance load 26.

[0047] As shown in Figure 1, the specific control process of the present invention is as follows:

[0048] 1. As shown in Figure 1, carry out finite element analysis to front bracket part 5, set up finite element model, obtain the analysis result of finite element, obtain the strain parameter of finite element ...

Abstract

A method for testing force-sensing includes analyzing finite element of component to be tested to obtain strain parameter of finite element, selecting out nominal optimized sticking-position combination of strain foil gauge from said strain parameters, sticking strain foil gauges on positions listed in said sticking-position combination as per specific angle to form Wheatstone bridge, lading electric charge on component to be tested and comparing calculated bridge voltage difference with actually measured bridge voltage difference and testing optimized sticking-position combination of strain foil gauge according to comparison result, applying said combination at on-site for selecting out most optimum one.

Description

technical field [0001] The invention relates to testing technology, in particular to a force measuring and sensing method. Background technique [0002] The realization of the load cell is to paste several strain gauges on an elastic body and connect these strain gauges to form a Wheatstone bridge through a line. When the force-bearing unit is deformed by force, the resistance of the strain gauge and The output of the Wheatstone bridge changes, and the relationship between this output and the main load is connected, and the force unit can be regarded as a load cell. [0003] If the shape of the part is complex, it will be difficult to determine the sticking position of the strain gauge. In order to facilitate the correct installation of the force measuring device, the traditional method of collecting loads is to remove (such as a car) parts or re-manufacture an identical load-bearing part, and sometimes think of some other methods, the basic principle is all around the mate...
