چکیده

در این مقاله به مطالعه و معرفی کاهش نیروی پسا در ساختارهای انعطاف‌پذیر پرداخته شده است. ابتدا مروری بر نحوة الهام‌گیری این پدیده از طبیعت انجام و در ادامه با استفاده از یک مطالعة تجربی ساده سعی در اندازه‌گیری عددی میزان کاهش نیروی پسای ساختارهای انعطاف‌پذیر شده است. نتایج نشان می‌دهد که این کاهش می‌تواند تا 50 درصد کل نیروی پسا هم باشد. همچنین، عوامل مؤثر بر این پدیده مورد بررسی قرار گرفته است.

چکیده [English]

In this paper, we study and introduce the drag force reduction in flexible structures. Firstly, a review of the inspiration of this phenomenon by nature is presented, and thenthe amount of drag force reduction in the flexible structure is measured experimentally. The obtained results show that this reduction can be up to 50% of the total drag force. In addition, influential factors on this phenomenon have been investigated.
