3. 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.
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.
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
24. 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.
