  5. 5. 3. RADIAL ENGINE This type of engine has one or more rows of cylinders arranged in a circle around a centrally- located crankcase.
  6. 6. 4. BASIC COMPONENTS OF RADIAL ENGINE • Master Rod • Piston • Articulated Rod • Cylinder • Crankshaft • Piston pin • Piston ring • Link Pin • Piston Plug Pin • Master Rod Bearing
  7. 7. 5. ABOUT THE MODELED ENGINE As we are concentrating on modeling and simulation of radial engine we didn’t go for the designing of various parts. For the dimensions of various parts of radial engine we referred the book of Prof. Sham Tickoo and edited some of the dimensions as per need (with reference of and

  19. 19. • Velocity of piston, Vp = ω×OM = 314.16×25.981 = 8.162 m/s. • Acceleration of piston, ap = ×NO = ×14.946 =1475.111 m/s. Approximate Analytical Method: • Velocity of Piston, Vp = ω×r( + ) = 8.652 m/s • Acceleration of Piston, ap = = 1391.58 m/s2 . Using CATIA V5 Software: • Velocity of piston = 8.778 m/s. • Acceleration of piston = 1200.13 m/s2 . Cont… ( +
  20. 20. 12. COMPARISON OF RESULTS The results obtained through the various methods for the velocity and acceleration of the connecting rod and piston are found to be satisfactory.
  21. 21. 13. DISCUSSION • In order to calculate the accelerations, we must first find the positions of all the links or elements in the mechanism for each increment of input motion, and then differentiate the position equations versus time to find velocities, and then differentiate again to obtain the expressions for acceleration. • From Newton's second law, “Dynamic forces are proportional to acceleration”. • We need to know the dynamic forces in order to calculate the stresses in the components.
  22. 22. 14.CONCLUSION Using CATIA software one can understand complete working of the radial engine(any model) before it actual designing and manufacturing.
