V profil kelepçede kuvvet oluşumunun analitik ve deneysel incelenmesi

V clamps are widely used in many industries as a pipe coupling fasteners, invented during World War II by the Marmon Corporation for use in the aircraft and aerospace industries. The V clamp was firstly used by NASA as a spacecraft separation system. Then, U.S. Army used Marman clamp to secure and to release the atomic bombs during transport at the end of the Second World War. In 1970s, Marman clamps transferred to civil industrial applications from military applications, called as V band clamp. Nowadays, V clamps have been widely used in a variety of applications including pumps, filtration, transfer pipe lines, exhaust and air intake systems due to its effective quick assembly and compact design advantages. Especially, in automotive industry, engine bay is getting more crowded because of emission reduction systems in exhaust line and air intake systems. In addition, increased production volumes and assembly costs require quick assembly on joints. So, the limited assembly space, quick assembly and weight saving requirements are increasing the usage of V clamps instead of traditional 2 or 3 bolted flange joints. Because only a bolt tightening is required to secure the V clamp joints, in contrast at least 2 or 3 bolts to be tighten in bolted flange joints. Ease of handling of V clamp assembly saves remarkable assembly time in assembly line. In addition to time saving, compact design of the V profile joints provides significant weight and assembly space savings. In this thesis, V clamps used in automotive industry are studied. In first chapter, academic literatures and studies will be reviewed and summarized. In second chapter, V clamps, design types, application areas with working conditions will be explained in detail. In third chapter, screw force calculation, radial force generation and axial force transmission on V band clamps will be studied. Also, V band clamp force theories will be implemented on V profile clamps. In forth chapter, material thickness effect will be added in actual theories as elastical deformation impact on V section of V profile clamp. In fifth chapter, the validation tests will be presented and the test results will be explained. Also, the test results will be compared with the generated theories. All the academic studies are based on V band and Marman clamps. The aim of this thesis is to create and implement force generation theories on V profile clamps by using actual V band clamp theories. And also, head touching effect in high temperature V profile clamp design with elastical deformation impact in V section will be investigated and the actual force generation theories will be developed further with these effects.
