First, the transmission shaft and crank shaft and so on in engineering and mechanical equipments, the majority deformation form is bending and torsion. This product can be used to measure strain, principal stress and principal stress direction under the combined stresses. It is an ideal tool to solve the problem of composite deformation under the combined stresses.
Second, strain measurement technology is one of the main means of stress analysis in engineering structure experiment. It is widely used in mechanical ,civil, aerospace and other engineering fields. For most engineering colleges, bending and torsion combined experiment of a thin-walled cylinder is a basic experiment of the stress test by electrical measurement.
System Composition and Principle
This product is designed with enclosed steel frame and cast composition with careful surface treatment. It is a durable fastening structure. For each type of experiment, the product equips with specimens and surface treatment samples and accessories. The system consists of experiment bench, Seamless Steel Pipe (hollow shaft), force sensor, strain gauge instrument, strain gage, cables, etc. The strain instrument can connect to a computer and the data can be processed with our software.
The basic principle of this strain-stress electrical measurement method: measuring a specimen's surface strain with strain gage, then the specimen's surface stress state is determined according to the strain-stress relationship. The strain-stress electrical measurement method is not only used to validate the basic theory of mechanics of materials, to measure the mechanical properties of materials, but also is a major engineering testing means for solving engineering problems. It provides a good experimental basis for scientific research.
