Abstract Centrifuges are often used to realize high-linear-acceleration in the test of thermovibration combined environment under high-linear-acceleration. At the end of it is located that vibrating table, temperature box, clamping fixture and test piece, which are often very heavy. The arm of centrifuge will be elongated as the result of large centrifugal force which is generated because of the high rotating speed, so the precision of output acceleration will be affected. Finite element method is used to analyze the deformation field of the arm of centrifuge in different rotating speed, and the relationship between the elongation of the centrifuge arm and the precision of output acceleration is analyzed, then the inherent characteristic of the arm vibration is analyzed, finally the valuable conclusions are gained.
