Virtual prototype based fatigue life research on some missile erecting system
MECHATRONICS AND INTELLIGENT MATERIALS III, PTS 1-3(2013)
Abstract
With some ballistic missile erecting system as subject, a virtual prototype is constructed, for virtual measuring of the load spectrum of the erecting system. By FEM analysis and damage analysis, the dangerous position of is uncovered, and the stress-time history is obtained. By use of material fatigue feature curve in combination with the stress-time history, the fatigue life of system components is studied.
