It is enough with relatively low cost, higher efficiency solves existing various problems during traditional unconfined compression test.
The utility model employs following technical proposal and solves its technical problem：A kind of unconfined compression test data are certainly
Dynamic acquisition and analysis device, including one without confining pressure instrument, this is equipped with upper loading plate and lower loading plate, upper carrying without confining pressure instrument
Ring of measuring one's own ability is equipped with plate, it is characterised in that：It is described without two displacement transducers are also equipped with confining pressure instrument, one is used to survey
The displacement transducer that annular of measuring one's own ability becomes, which is fixed to be placed in, measures one's own ability in ring, and another is used to measure measured object height in test process
The displacement transducer of change is fixed and is placed between loading plate and lower loading plate, and described displacement transducer signal output end passes through
Data wire connects the signal input part of data collecting card, and the signal output part of the data collecting card connects computer by data wire
Signal input part.
The utility model has the advantages that：
（1）It is simple in construction, with relatively low experimentation cost can configure on existing unconfined compression test instrument excellent
Change；
（2）By the associated working of displacement transducer, data collecting card and acquisition and analysis device, tradition is efficiently solved
Existing data acquisition and record are complicated during unconfined compression test, and experiment process duration is long, efficiency is low, manually
The problems such as data acquisition error in reading is larger, critical data point is lost；
（3）Can dynamically set frequency acquisition, and the data of collection handle in real time, calculated, can automatically, standard
Really, comprehensively, quickly gather, analysis test data, it is accurate quick, it is easy to use, operating efficiency can be greatly improved.
