Model Algorithm

Разработана математическая и симуляционная модель для моделирования биомеханических движений конечности человека. Разработанный алгоритм модели базируется на биологическом представлении о включении и выключении в процессе удержания положения конечности отдельных мышц или их групп. Работа модели осуществляется за счет генерации случайных чисел (в математической форме симмуляционной модели отсутствуют статические величины). Сравнительный анализ экспериментальных и модельных данных показывает высокую эффективность работы симуляционной модели. Созданная симуляционная модель позволяет изучать принципы работы нервно-мышечной системы. Также модель является масштабируемой, что позволит в дальнейшем перейти к трехмерному моделированию для изучения механизмов самоорганизации биосистемы на уровне и нервно-мышечной системы, и центральной нервной системы. Mathematical and simulation model has been developed for modeling the biomechanical movements of a human limb. The developed model algorithm is based on the biological presentation and shutdown in the process of maintaining the positions of the final individual muscles or their groups. Work in models is due to statistical values. A comparative analysis of experimental and model data shows the high efficiency of the simulation model. The created simulation model allows to study the principles of the neuromuscular system. This model is scalable, which will allow us to switch to three-dimensional modeling to study the signs of self-organization of biosystems at the level of the neuromuscular system and central nervous system.

Very complicated as the cycloid wheel movement appears, tridimensional software Solid Works is applied to outer planetary cycloid wheel parts modeling and dynamic simulation with the outcome meeting the prospective design requirements. Therefore, we conclude that tridimensional modeling will be applicable for mechanical designing with great significance. In response to increasingly complicated product designing, the roles of the tridimensional modeling approach will be brought into fuller play. In pin-cycloid gearing, due to the specially curved and differential gear surface, the gearing accuracy and service life of the pin-cycloid are both affected. To get a smooth solution to the problem of the tridimensional surface shaping, priority shall be given to precise drawing of the gears profile curve [.

In this article, we research on the flip device of steel cutting machine, doing kinematics analysis to the discharging mechanism, calculating the operating parameters of the mechanism and optimizing the operating parameters of the flip device. With the using of three-dimensional modeling software UG NX7.5, reinforced flip device is precisely modeled, and all parts it concluded are assembled together, then whole mechanism kinematical simulation is carried out. The optimum flip angle of the unloading mechanism is obtained through the study of the Simulation results. By analyzing the displacements, velocity, acceleration and other data of unloading rack at any moment in the working process, the optimized design of discharging mechanism is given. Finally, the stability of discharging mechanism is analyzed.

Modeling Analysis

A turbine aerodynamic optimization design system for marine gas turbines has been investigated to accelerate the turbine aerodynamic design process and perfect the research and development platform. The data can be conversed automatically with the self-compiling programs which integrate the 1D, S2 module of Concepts NREC, three dimensional modeling, analysis, and optimization of NUMECA. At the same time, the system can satisfy multilevel optimization design easily for different requirements. And the system has been used in the optimization design of a marine gas turbine. The results show that the design period can be reduced; after optimization the efficiency is improved about one percent; and the off-design performance is improved due to the rear loading technology.
