볼트의 체결 강성이 추력 시험대에 미치는 영향

This paper is studied on the effect of the bolt joint stiffness on the Thrust Measurement Stand(TMS). TMS is a test stand for thrust performance of the propulsion system, which depends on two factors: The 1 st is the parallel degree between directions of the thrust vector and action lines of the corresponding measuring load cells for the vector, and the 2 nd is the orthogonality between action lines of the measuring load cells. Therefore, it is essential to maintain the original shape of the TMS under operating conditions. In this paper, it is examined how the geometric tolerance of the bolt joints and threads of the load cell trains affect the performance of the TMS. Also, some techniques to overcome related problems are provided.
