In order to improve Z-shaped pipe in the directly buried heat-supply pipeline with large diameter stress calculations, guiding the engineering design when the short arm length is less than two times the elastic arms length. The author used ANSYS software to numerical simulation analysis on Z-shaped pipe in the directly buried heat-supply pipeline of DN800, DN1000, DN1200, when the long arm length of 50 m, 100 m, 150 m, and the short arm length from two times to one times of the elastic arm length. Applying boundary conditions in different models with the short arm length shortens the process to Z-shaped pipe of the elbow stress. For Z-shaped pipe in the directly buried heat-supply pipeline the short arm from two times to one times of the elastic arm length, the elbow’s stress value is the minimum when the short arm length is 1.2 times of the elastic arm length. This article breaks the specification limits on the short arm length, improving the flexibility of directly buried heat-supply pipeline with large diameter, reducing the difficulty of construction, and it’s important for guiding the actual project.

According to the situation that the dual-friction drums on the new type towing machine lack stress analysis when designed, the safety is difficult to test and verify. The pull of wire rope in various positions was derived and calculated, so both compressive stress and tangent friction force generated by the pull of wire rope were calculated. The result made by ANSYS software demonstrates the safety of the left drum which suffers from larger loads, structure improvement measures are put forward for the drum.

Cylindrical Roller

A dynamic finite element analysis model for cylindrical roller bearing is developed, and the complex stress distribution and dynamic contacting nature of the bearing are investigated carefully based on ANSYS/LS-DYNA. Numerical simulation results show that the stress would be bigger when the element contacting with the inner or outer ring than at other times, and the biggest stress would appear near the area that roller contacting with the inner ring. Phenomenon of stress concentration on the roller is found to be very obvious during the operating process of the bearing system. The stress distributions of different elements are uneven on the same side surface of roller in its axis direction. Numerical simulation results can give useful references for the design and analysis of rolling bearing.

The Finite Element Model

In order to study the static and dynamical characteristics of the crankshaft, ANSYS software was used to carry out the corresponding calculations. The entity model of the crankshaft was established by UG software firstly, and then was imported into ANSYS software for meshing, and then the finite element model of the crankshaft was constructed. The crankshaft satisfied the requirement of stiffness and strength through static analysis. The top six natural frequencies and corresponding shapes were acquired through modal analysis, and the every order critical rotating speed of the crankshaft was calculated. The fatigue life of the crank was calculated by fatigue module of ANSYS software finally. These results offered the theoretical guidance for designing, manufacturing and repairing the crankshaft.
