摘要

The mechanical system of large-scale medical imaging equipment SPECT is complex and expensive, so it is difficult to carry out the reliability test with a large number of physical equipments. The virtual test method is used to evaluate the reliability of the system. The virtual prototype of SPECT mechanical system is established with SOLIDWORKS. The force load between components was obtained through dynamic simulation in ADAMS software. Finite element static analysis in ANSYS software was used to obtain the stress and strain distribution. Based on the S-N fatigue analysis method, the fatigue life cloud chart and the fatigue damage cloud chart of the key components are calculated in the nCode software to determine the fatigue failure site, which provides the basis for the reliability design and equipment maintenance of the SPECT mechanical system.
