Abstract:
      On the basis of stress-strength interference distribution theory and reliability designing method,mathematical modeling of reliability calculation based on P-S-N (Reliability-Stress-Life)has been made,while numerical solution with high accuracy has been fulfilled by computer program through probability density distribution curve interference interval integral 、compounding trapezium principle and Simpson principle.The example shows:compared with traditional method of reliability calculation,the calculation accuracy of system reliability has been significantly improved.The research achievement has its background in engineering application.
