Fixations of underbody with chassis. For example, Boeing 777 featured an all-composite empennage and composite floor beams. The virtual prototype model in the UG was built, the FEA model was built, and the strength is studied of the SLEE’s key parts by finite element simulation with the finite element analysis software. Worked on various program for design and structural analysis of Bus structure and Heavy duty crane etc. Perform finite element analysis on composite parts for layup optimization.
