打音特性に基づくエレベーターの薄肉かご側板構造の検討(昇降機・遊戯施設等の最近の技術と進歩)

抄録

For space-saving and cost-reduction of elevators, the reinforcement materials of press processing were joined by projection welding, and the panel structure that raises rigidity was developed. This example, which applied the knocking sound characteristic of a panel to the evaluation parameters at the time of development, is reported in that case.
