Based　on　the　analysis　of　the　test　data　and　Miner＇s　rule,　a　combined　high　and　low　cycle　fatigue　(CCF)　life　prediction　model　considering　the　loading　interaction　is　established　by　introducing　coupled　damage.　The　coupled　damage　is　determined　by　multiplying　the　high　cycle　fatigue　damage　and　the　low　cycle　fatigue　damage　by　a　coupled　damage　coefficient　K$$　K　$$.　According　to　the　analysis　of　the　test　data,　the　coupled　damage　coefficient　K$$　K　$$　is　positively　correlated　with　the　high　cycle　stress　ratio　R$$　R　$$.　In　addition,　an　interaction　factor,　which　reflects　the　loading　interaction　effect,　is　introduced　to　correct　the　coefficient　K$$　K　$$.　The　CCF　experimental　data　of　four　materials　are　employed　for　model　verification　and　comparison　among　the　proposed　model,　Miner＇s　rule,　and　Trufyakov-Kovalchuk　model　(T-K　model).　The　proposed　model　exhibits　a　relatively　higher　prediction　accuracy　and　is　more　suitable　for　predicting　the　fatigue　life　of　CCF.
