The cutter body is composed of the boring cutter support body, a middle boring cutter body and a boring cutter body. The chip removal mode disclosed by the invention is rear chip removal in the external chip removal.

A prediction method suitable for non-uniform large deformation grade of soft rock tunnel
ActiveCN110489844BThe optimization method is scientific and reasonableImprove accuracyGeometric CADForecastingRock tunnelInitial sample
The disclosure provides a method suitable for predicting uneven and large deformation levels of soft rock tunnels, which acquires the geological conditions, construction conditions and deformation data of each existing soft rock tunnel, and classifies the degree of uneven deformation into basic deformation levels and uneven deformation Level, classify and quantify the main influencing factors, and establish the initial sample database of soft rock tunnel with uneven large deformation; use different methods to calculate the subjective and objective weights of the main factors to obtain the comprehensive weight, and use the gray relational degree theory to calculate the influencing factors and soft rock tunnel respectively. The degree of correlation between the foundation deformation level and deformation unevenness level of the rock tunnel is reduced, and the influencing factors whose correlation is less than the set value are reduced; the reduced influencing factor indicators are used as input parameters, and the foundation deformation level and deformation unevenness level are output Parameters to construct the artificial neural network prediction model of soft rock tunnel with uneven large deformation; input the collected data of the soft rock tunnel to be predicted into the artificial neural network prediction model to obtain the prediction result.

Method for preparing amorphous film with gradient structure based on high-temperature ion irradiation
ActiveCN113718200AImprove plastic deformation abilityHigh strengthFinal product manufactureVacuum evaporation coatingPhysical chemistryThin membrane
The invention discloses a method for preparing an amorphous film with a gradient structure based on high-temperature ion irradiation. The structure is characterized in that on the basis of adopting a high-quality amorphous film plated by magnetron sputtering, high-temperature ion irradiation treatment is assisted, so that the surface of a sample is crystallized, and the interior of the sample is kept in an amorphous structure; and therefore, the high-strength and high-plasticity amorphous film with the gradient structure is prepared. The gradient amorphous thin film structure prepared by the method can be easily realized by controlling the temperature and the implantation dosage of an ion irradiation experiment, so that the possibility is provided for preparing a controllable amorphous thin film material with high mechanical property.
