Abaqus Software

The Abaqus software was used to simulate the creep behavior of a cylindrical tube of Sanicro-25 austenitic steel under an internal pressure of 11.3 MPa at a uniform temperature at 750 °C. The data used for the simulation input were obtained from the experimental data of a previous work. The hidden information of material parameters was estimated from the shape of creep strain versus time plots obtained from the experimental data. The validated results between the simulation and the experimental data produced the material parameter of the creep power law which were set at 2.6 x 10-22 for the power law constant and 9 for the stress exponent. The parameters were further used to explore the stress and strain inside and outside of the tube wall and the thickness changes of the tube wall.

Random Vibration Analysis

In this paper, the random vibration theory based on the finite element is briefly described; the appropriate finite element model of the Deployable Structure for Satellite Antenna (DSSA) is created. In order to assess the random vibration characteristic and the performance of the DSSA in the dynamic environment, the responses of the DSSA are analyzed. The responses are obtained by the respective random vibration analysis of X, Y, and Z directions, and by the analysis of the root mean square and the power spectrum density of the acceleration response. The results show that, although the DSSA can bear the random vibration load, the structural weaknesses are existence. This provides some references to the formal design of the DSSA.

Traction System

During the operation, the high speed train will be subject to random vibration load induced by the roughness of the rail and will cause the vibration. Traction motor is critical component of traction system for high-speed train. It is subject to not only static loads, but also random vibration load. This kind of random vibration load may easily lead to fatigue damage of the structure, which will finally cause adversely effect to the motor. Thus, in this paper, a 3-dimension model of the support system of traction motors in high-speed train applications is built, and the static and modal analyses are undertaken using finite element calculation software. The simulation results confirm that the support system is robust enough to meet the design requirements of strength and stiffness. Furthermore, it has a larger margin of safety in a typical case which meets the technical requirements for safe operation of the high-speed train.
