Reliability Design and Performance Analysis of ATS

Focus on the continuously improved requirements for systemic reliability under the complex transporting conditions such as a larger quantity of projectiles, multiple kinds of ammunitions, high-speed working rate, heavy loads and random working states, the design rules are built based on failure forms of the working parts from the default values of the systemic reliability. The rapid allocation of reliable degrees and the probability distribution selection of systemic parts and components of ATS (ammunition transporter system) is made due to the AGREE method. Then, the structure under the working conditions is designed and the reliability model of the structure with hybrid modules is built on the working principles of ATS. What's more, the reliability simulations of ATS under the multiple load conditions is made utilizing the FEM software. The results show the following points: ATS structure designed by rapid reliability method meet the design requirements for the systemic reliability; the structural functions and mechanical performances are better than the structure designed by the method of classic safety factors; RRM is convenient and reliable for system reliability design.
