ABSTRACT •In the Under Frame manufacturing there is a process called Camper setting which is done for withstanding the entire load, vibration, stress etc. the process is done manually by using the Screw jacks and tie rods •Due to manual process, time consumption is more and accuracy is less. To overcome this problem, the hydraulic piston is introduced to camper the under frame in the train compartment.
- 4. MAINCOMPONETS OF COACH • Under frame • Side walls • End wall assembly • Roof assembly • Bogies
- 5. PRICIPAL OF FIXTURE • Locating • Clamping • Fool proofing
- 6. IMPORTANCE OF FIXTURE • To reduce the production time • To reduce the cost of production • To increase the accuracy • To minimize the machining time • To reduce the operator fatiuge
- 7. CAMBER CAMBER Camber is a profile .It’s depend to raise a height as per measure respectively .so it’s called negative deflection . Why this needed? Camber setting is to avoid a creep stress on a dynamic load.
- 9. CAMBER SETTING PROCESS • Zero point setting • Side wall clamping
- 10. VIEW OF ZERO PIONT
- 12. CAMBER SETTING USING HYDRAULIC SYSTEM • Hydraulic cylinder • Pressure relief • DCV • Flow control valve • Pilot operating check valve • Pressure gauge • Hydraulic motor and pump
- 13. MERITS OF USING THIS SYSTEM • Time consumption less • High accuracy • Simply to operated • Semi skilled labour
- 14. DESIGN CALCULATION • Hydraulic cylinder for deflection 15 mm • Hydraulic cylinder for deflection 6mm
- 15. 15 mm DEFLECTION • Weight lifted by 1 cylinder = 144587/2 = 72294 N • Taking diameter of the cylinder as 80 mm • Area = p/4* 802 = 5026.24 mm2 • Pressure = Load/ Area = 72294/5026.54 • Cylinder Thickness = 5 mm • Therefore, outer diameter of cylinder = 90 mm • Cylinder volume = stroke* area = 417*p*802/4 = 2.096E6 mm3 = 2.096E-3 m3
- 16. 6 mm DEFLECTION • Weight lifted by one cylinder = 54255.825 N • Taking diameter of cylinder as 80 mm • Area of cylinder = p/4* 802 = 5026.24 mm2 • Pressure = Load/ Area = 54255.825/ 5026.54 = 10.79 N/mm2 • By measuring the distance between the bottom of under frame and ground, stroke length is taken as 417 mm • Cylinder Material is Mild steel • Cylinder volume = stroke* area = 417*p*802/4 = 2.096E6 mm3 = 2.096E-3 m3

CONCLUSION • Thus, our project Design of Hydraulic system for Camber and Pneumatic systems for Side wall assembly completely aims on the time scaling and also with the view to reduce man power • Thus, we hope that this project work will surely satisfy the workers who are involved in the camber setting method and also in the side wall assemblies.
