In the article a hydrodynamic flow model for microfluidic MEMS is presented. Methods and tools for design automation of microfluidic flows were applied. The possibilities of modern CAX tools for the simulation and optimization of fluid flow in microchannels were analyzed.
In this article patterns of development of tension-deformed state of canillary–porous materials with variable heat-mechanic characteristics in the process of drying, depending on the characteristics of the environment, were resulted. The influence of the parameters of drying agent on the dynamics of stress in the wood was investigated on the basis of numerical experiment.
To determine the optimal parameters of the dynamic vibration absorber (DVA), a complete multi-parameter model of the dynamics of machines and structures is required. A model with two degrees of freedom is unacceptable for a sufficiently precise calculation with sufficient accuracy of the oscillations of the design, and thus for an adequate description of its dynamic characteristics. Therefore, in practice, it is necessary to investigate the design using a complex model.
This article is devoted to development of model, based on Petri nets, which corresponds planning stage of RTS automatic design. The model was developed according to the algorithm of the planning stage, which is the basic one in five-level representation of the robotization project estimation process, and enables to explore the dynamics of the process and the reliability of the corresponding component of the RTS design system, also providing the possibility of additional RTS correction in a broader functional and constructive spectrum.
In the article is an example of a vibrating hopper feeder full methodology described his design with the withdrawal of the main analytical dependencies that set the parameters of the system
For the specified ski courses relief research the algorithm and then the program ‘Course Calculation’ were developed. On the basis of the two-dimensional terrain image it is possible to design the arbitrary amount of ski courses profiles variants. The basic parameters
of the ski course relief are determined and also compared to the normative values
