In the country, from the brand name, equipment and services are relatively perfect, there are three: GOM, CSI, Xibo three-dimensional. These three technology is not a big difference, the products are basically used in high-end research institutes, or some key colleges and universities, such as domestic Tsinghua University, Zhejiang University, Tongji, foreign ABB, Audi and so on. Tongji before the tender to invite these three special competition, but also on their own product recognition. The first two of the three brands are foreign brands, in the country is an agent sales model, the latter is a domestic brand, technology from XJTU. From the brand, the general foreign conventional equipment should be in the six hundred thousand or so, the function of the advanced point of the basic are in the million or so. Domestic brands are relatively affordable, conventional equipment should be about four hundred thousand, but high-end also more than a million.
From the application, there are high-temperature strain measurement, there is a measurement of damage to the test, there is a measurement of the large size of the tensile and so on. Different applications require different configuration programs. This can only be specific experiments specifically analyzed, the prediction will vary too much, it is best to ask the manufacturer according to the specific circumstances.
