In order to solve thermal deformation, the finite element numerical simulation of two kind of tilting pad thrust bearing is made for the same pad surface, and thermal deformation is made to analyze comparatively. The results show that the temperature field, the deformation field and the values of pad are similar for two different supported thrust bearing (point, line support) under the same operating condition. The pad temperature and deformation will increase with the increasing of pv values. According to the calculation conditions, the temperature field rose about 1°C, and the thermal deflection increased 0.002mm with pv value increased by 10%.

The temperature field is an important aspect to study the interaction mechanism between the laser and glass. The temperature distribution on the surface of the glass that illuminated by the CO laser is numerical simulated by using the finite element method. The change of the temperature field of the target, irradiated by the laser in different time or different power, is simulated respectively, get the curve of the temperature field which reflects the temperature at the center spot changing with the action time and power.

The thermal displacement of a large scale footbridge is investigated in this study through numerical simulation. With appropriate assumption, the temperature field of the footbridge is simplified and divided into several components. Fine finite element models are constructed for the deck plate, bridge section, and bridge tower to calculate the structural thermal effects. The made observations indicate that the thermal deformation of the bridge tower is much larger than that of the deck due to the cable sag under temperature increase.

Optimizing Design

Friction between the guideway and the bench of large-type CNC lathe will cause thermal deformation of the guideway, which causes processing error of the lathe，thereby reduces machining precision of the workpiece. The authors establish the mathematical model of temperature field and thermal deformation of the guideway in the work process, numerically simulate the guideway thermal characteristics by ANSYS finite element analysis software, and obtain the distribution regularities of temperature field and thermal deformation and their major influencing factors, which provide a theoretical basis for optimizing design and thermal error compensation design of the lathe guideway.
