In this paper, the present status and the purpose of study on thermal-vibration combined environment under high linear acceleration are introduced. The technical matters about the design of centrifugal machine, the high temperature change rate and evenness degree of proof box and the armature deflection of electric vibrator under centrifugal force field are discussed, which appear in the trituration of thermal-vibration combined environment system under high linear acceleration, and corresponding theoretical analysis and experimental investigation are proceeded. Finally, the responding processing method is presented.
