- W2357103612 abstract "Objective To investigate the dynamic characteristics of a certain space unit and propose a modified plan to improve the local stiffness of space unit with computer simulation.Methods The MSC.Patran was used to create the finite element model(FEM) of the space unit,and MSC.Nastran to compute its mode shapes.The method's validity was verified by comparing the simulation results with the actual vibration test results.Results The space unit endurance ability to space vibration environment was discussed.Two practicable modified plans were provided in order to improve the local stiffness of space unit in the case of the function of the space unit fulfilling its requirements.The dynamic characteristics of the two modified structures were predicted with the same numerical simulation program.Conclusion The simulation study method for improving local stiffness of a space unit can offer the theoretical reference for structure modification of the space unit.This technique can be applied to space unit endurance design to vibration environment." @default.
