3.0      CALCULATION 3.1      Model The stresses in the liner are calculated using an axisymmetric finite element model of the liner as shown in Figures 1 and 2. Contact (gap) elements are included between the liner and block to simulate the contact force. The finite element model of the cylinder liner was developed using nominal dimensions for the liner and engine block. As described below, other cases were also evaluated to determine the effect of changes in some of the.liner dimensions.

3.2        Applied Loads/Boundary Conditions The liner is subject to the following loads and boundary conditions (as shown on Figure 4):
* Bolt Preload - The cylinder liner is held in place by the head. The preload in the head bolts is applied as a pressure to the head/liner contact surface. This load is ultimately reacted by contact with the engine block mating surface under the liner flange. This force is applied as a pressure load as shown in Figure 4.

* Piston Transverse Loads - During piston motion, the cylinder liner reacts the piston transverse load. This load is minimal at the piston high point (firing). It is significant only when the piston is at lower positions. Since the transverse load is not significant when the piston is at the high point, transverse loads do not significantly affect the stresses near the flange. Therefore, this load is neglected in this analysis.

* The engine firing pressure reduces the stresses in the groove. However, the stresses remain tensile over the full load cycle.
* The nominal strength of the liner material is about 36 ksi. The maximum stresses in the liner reported in Section 2 are local stresses concentrated at the inside surface of the relief groove. The liner likely can withstand maximum calculated elastic stresses slightly greater than 36 ksi. Based on the calculated stresses (and neglecting thermal stresses), the liner likely would not fail for the nominal case. However, the worst case stresses are significantly greater than the nominal stresses and local failure or damage could occur.

1.0 PURPOSE The purpose of this calculation is to estimate the stresses in an ALCO 251 diesel engine cylinder liner. The stresses are calculated for the nominal liner configuration and several other configurations to evaluate the effect of variations in design parameters. 2.0 RESULTS For each case evaluated the maximum stress occurs at the relief groove, at a location about 45° from the groove/flange intersection. The principal stresses at this. location are oriented at an angle of about 45°. The maximum calculated stresses are summarized below in the "principal stress" coordinate system (rotated 45°).

3.0 CALCULATION 3.1 Model The stresses in the liner are calculated using an axisymmetric finite element model of the liner as shown in Figures 1 and 2. Contact (gap) elements are included between the liner and block to simulate the contact force. The finite element model of the cylinder liner was developed using nominal dimensions for the liner and engine block. As described below, other cases were also evaluated to determine the effect of changes in some of the.liner dimensions. The key dimensions used in developing the model are shown in Figure 3. The primary references for the dimensions are References 1 and 2, the Bombardier Design Print for the liner and the ALCO 251 Technical Manual. These dimensions are summarized below: RR4=1/2 BLKIR=l0.752/2 RR5=5/8 RELIEF=0.133 DEPTH=0.05 Cl=R3-9.8/2 FLOFF=0.0001 (the flange offset) LTOT=21+15/16 IR=9/2 Ll = 1.732*(R2-Rl) R1=(9+9/16)/2 L3=0.333 R2=10/2 L5=5/16 R3=10.254/2 L7=5/16 R4=10/2 L6=(14+ 7/16)-(13+5/8)-L7 R5=10.2/2 L4=(2-L5-L7-L6)/2 R6=10.71/2 L2=LTOT-1.455-(14+ 7/16)-L1-L3-L4-L5 R7=10/2 L8=L4 R8=10.75/2 L9=0.333 R9=11.865/2 Lll=0.339 R10=R9-l/4 L10=(13+5/8)-L8-L9-(2+ 1/16)-3/8-1.5-Lll Rll=l0.660/2 L13=0.571 R12=10/2 L12= 1.5-L13 R13=(9+ 19/32)/2 L14=3/8 R14=R9-1/8 L15=0.478 BLKOR=R9+0.25 L17=0.573 BLKHT=0.75 L16=(2+ 1/16)-9/16-Ll7-LlS RTAN =RS-DEEP+ RELIEF L18=9/16 L20=7/16 RRl=l/2 L21=1/8

E = 16,000,000 psi (Reference 3 states modulus of elasticity is 14-17 ksi) v = 0.3 (assumed) The ANSYS general purpose finite element program is used to calculate stresses. Attachment 1 is a listing of the ANSYS input for the nominal case. The inputs for the other cases a~e similar. Two key assumptions were made developing the model. These are summarized below.

  • The analyses neglected friction effects at the lower seal (at the 0-rings). This friction force could reduce the calculated stresses if the rotation of the liner flange was restrained.
  • The potential for contact between the lower, upper guide is neglected. Although this contact is not expected, it could lower the calculated stresses.

3.2 Applied Loads/Boundary Conditions The liner is subject to the following loads and boundary conditions (as shown on Figure 4):

  • Bolt Preload - The cylinder liner is held in place by the head. The preload in the head bolts is applied as a pressure to the head/liner contact surface. This load is ultimately reacted by contact with the engine block mating surface under the liner flange. This force is applied as a pressure load as shown in Figure 4.
