Static analysis of exciting force in chain continuously variable transmissions (CVT) with a geometric model

Taking minimum compliance of the whole structure as the objective, the mathematical optimization model of multi-loading cases topology optimization is constructed by using the weight compromise programming method to coordinate the multiple objective functions. The optimal topology of the work flat is obtained using Hyperworks/Optistruct software and geometric model is reconstructed. The static analysis of original and reconstructed structural models of the work flat show that the optimized structure can not only decrease the weight, but also improve the stiffness and reduce the stress. The work flat will be more safe and reliable than before.

Worm is the executive component of the twin-screw oil press, and the design of the worm effect the performance of twin-screw oil press. In this paper the 3-dimensioned geometric model of the worm was established with SolidEdge, the static analysis for the established model was finished and the natural frequency of the worm was analyzed with ANSYS Workbench. Then the first six level natural frequencies and vibration mode were obtained, which provide the basis for dynamic analysis of the worm.

The article discusses the method of solving the task 18 on the Unified State Examination in Informatics (Russian EGE). The main idea of the method is to write the conditions of the problem utilizing the language of formal logic, using elementary predicates. According to the laws of logic the resulting complex logical expression would be transformed into an expression, according to which a geometric model is supposed to be constructed which allows to obtain an answer. The described algorithm does allow high complexity problem to be converted into a simple one.

In this study, the seismic behavior of the concrete shear wall considering the opening with different shapes and constant cross-section has been studied, and for this purpose, several shear walls are placed under the increasingly non-linear static analysis (Pushover). These case studies modeled in 3D Abaqus Software, and the results of the ductility coefficient, hardness, energy absorption, added resistance, the final shape, and the final resistance are compared to shear walls without opening.
