Reliability Analysis of Statistical Failure Probability in Sin/Hip $Si_3N_4$ (III)

ABSTRACT

KIST/CARES reliability analysis program was used to calculate failure probabilities of piston pin and poppet valve. The 4-point bending test was performed on Sin/Hip Si3N4 for obtaining material parameters such as m, $sigma$o, and KB, and the finite element analysis was performed using MSC/NASTRAN for obtaining stress distribution. The calculated failure probability of piston pin was lower than 10-6 and the failure probaility of poppet valve was greater than 0.95.
