- The traditional fork pin connects the next part in hydraulic/pneumatic cylinder with the help of bolt and nut. But,main problem occurs, when motion is transferred through the existing pin, the nut could be loose due to improper fittingand due to vibrations produced by the piston stroke, may get detached from the assembly. Because of this problem, theassembly may get disassembled and may damage to other parts and leads to catastrophic failure. Another problemconsidering, tightening & loosening of both nuts consume too much time. So in this research, with used of design of Xconcept which suggests to replace screw-nut type fasteners with snap fits in DFA approach. So here, the main aim is toreplace traditional nut & threaded pin with modern snap on spring fork pin by making effort on high strength to withstanddesired motions and emphasizing on ease of locking and unlocking with snapping concept by improving pin stress. Sohaving said that, with the use of CREO modeling, analytical analysis, ANSYs based an alysis, it has been carried out athroughout analysis of fork pin with its assembly of existing design and the modified snap on spring fork pin assemblydesign by using comparative results with the practical conditions to achieve maximum strength and ease of locking andunlocking.
