通过本文的理论推导表明，扭转振动摆动辗压的效率与振动频率和进给速度成正比，扭转振动摆动辗压成形的成形效率比纵向振动摆动辗压成形的成形效率高。
The theoretical derivation shows that the vibro-rotary forging efficiency is directly proportional to the vibration frequency and feedrate and higher than that of longitudinal vibration forging.
桌面化快速成形系统不仅需要在高速扫描时保证足够的精度，还需要尽可能地减小振动和噪声。
Rapid Prototyping Desktop System needs not only to achieve enough part precision in high speed scanning but also to reduce the vibration and noise as most as possible.
