In this paper, the structural strength of a rolling stock seat were numerically evaluated under several design load conditions based on the UIC requirements. The rot]ins stock seat was designed for the high speed train of a Chinese conventional line. To maximize its weight reduction and structural strength, an aluminium alloy, ALDC8-T5, was applied to the base frame, side frames and armrests. The designed seat frame satisfied the strength requirements on inertia loads and fatigue test conditions. However, it couldn't satisfy the requirements on the static test conditions of UIC 566 OR. Therefore, some design modifications were suggested and numerically evaluated whether the static test requirements could be satisfied or not.
