This paper introduces the concept of digital prototype technique and its necessity of applications in the design of servo mechanism of some launch vehicle. This paper explains the applying process with digital prototype technique in the design of servo mechanism. The applying contents with the technique, including analyzing load characteristic of servo mechanism by MAT- LAB, analyzing kinematics of mechanism by ADAMS, analyzing mechanics of the key parts by ANSYS and assembling three dimension structure modal by Pro/E, were described in detail. Through the application of the technique, the quality and efficieney of design is improved, the developing schedule of servo products is accelerated and the costs of production are reduced. Finally, the authors summarize the applications of the technique in the design of servo mechanism of some launch vehicle and propose its developing trend in the future.
