摘要： A reinforced shipping container along with method for generating the reinforced shipping container are described herein. A digital model of the shipping container is received and simulated with an expected load. The expected load may represent an expected loading scenario for the shipping container during shipment. A reinforcement profile is determined based on stress data developed from the simulation to increase a strength-to-weight ratio of the shipping container. The reinforcement profile is used to apply a reinforcing agent to a substrate used to form the shipping container in a selective manner to reinforce regions of the shipping container that will experience stresses during shipping.

摘要： A springback variation cause analysis method includes: calculating a first stress distribution in a press forming part; calculating a second stress distribution in the press forming part; calculating a difference between the second and the first stress distribution, and replacing and setting the first or the second stress distribution with the calculated stress difference distribution; calculating a first springback amount to be caused in the press forming part; changing a value of stress difference in a partial area of the press forming part in the stress difference distribution set for the press forming part; calculating a second springback amount; and analyzing a portion in the press forming part that is a cause of variation in springback amount in the press forming part due to scattering or variation in press forming conditions, based on the second springback amount and the first springback amount.

摘要： A method for constructing a free trajectory of a ballistic missile at a specified launch angle includes: setting of an initial state of iterations: based on geodetic coordinates of a launch point and a target point, a launch epoch and the specified launch angle, assuming that the earth does not rotate and a flight time is zero; generating a new flight time in a two-body force model by using known quantities and obtained auxiliary quantities; taking a difference between flight times obtained before and after the iterations as a condition for judging convergence; outputting designed parameters of the ballistic missile after the convergence is reached, or performing a differential correction including the J2 perturbation to improve the precision of the trajectory constructed, and taking a position error of the target point as a convergence condition of the differential correction.

摘要： A structure including a plurality of dielectric regions is described. The structure can include a rivet cell. The rivet cell can include a set of stacked vias. The rivet cell can extend through a stress hotspot of the structure. A length of the rivet cell can thread through at least one dielectric region among the plurality of dielectric regions. The rivet cell can be among a number of rivet cells inserted in the stress hotspot. The stress hotspot can be among a plurality of stress hotspots across the structure. A length of the rivet cell can be based on a model of a relationship between the length of the rivet cell and an energy release rate of the structure. The rivet cell can thread through an interface between a first dielectric region and a second dielectric region having different dielectric constants.

摘要： The present invention relates to a prediction model for a lip sticking force of a cigarette tipping paper, a construction method and a prediction method thereof, which belongs to the technical field of analysis and detection. In the method, the stepwise regression analysis is performed on the lip sticking force and values of the dynamic friction coefficient and the grammage of the cigarette tipping paper to obtain a model for predicting the lip sticking force of the cigarette tipping paper. When checking the accuracy of the model, it is found that the predicted value and the measured value basically fall near the 1:1 line, R2 index is 0.99, and the normalized root mean square error (nRMSE) is 2.64%. The present invention provides a method capable of quickly and simply quantifying a sticking force of the cigarette tipper paper to lips.

摘要： The present invention discloses a numerical simulation method for proppant transport considering wall-retardation effect, comprising the followings: establish a physical model of laboratory experiment on proppant transport with a large flat-panel device; establish a drag coefficient model considering wall-retardation effect according to the numerical simulation experiment; establish a computational geometric model; set boundary conditions and physical parameters of the geometric model according to the two-fluid simulation method for solid proppant quasi-fluidization; verify the grid independence of the computational geometric model to obtain the transport characteristics and placement pattern of the proppant in fractures. The present invention employs a numerical simulation method to study the migration and distribution patterns of proppant under the retardation effect of narrow walls during the hydraulic fracturing. The method is reliable in principle and can accurately predict proppant transport in subsurface hydraulic fractures with consideration of the wall-retardation effect on proppant transport.
