小型磁带机是在不同的动态环境中使用,与地面计测磁带机相比,有许多不同的设计要求和特点。在记录重放电路中要使用抖动补偿电路,或消跳动、消扭动缓存器;在运带机构设计方面,要消除运带系统的低频谐振,确定在振动环境中各个部、元件的谐振频率,并采取减小抖动的措施,以及选译合适的带速控制。文中提出了计算运带系统固有频率的二个数学模型,使用109丙数字计算机求解出整个系统的固有频率,并与实测值作了比较,得出了一些结论。
Small drives are used in different dynamic environments and have many different design requirements and features compared to ground-based tape drives. In the recording and replay circuit to use the jitter compensation circuit, or eliminate the beat, cancel the wrung buffer; in the transport mechanism design, to eliminate the low frequency resonance of the carrier system to determine the various parts in the vibration environment, the resonant frequency of components , And take measures to reduce jitter, as well as the election of the appropriate speed control. In this paper, two mathematical models for calculating the natural frequency of the belt system are proposed. The natural frequency of the whole system is solved by using 109 C digital computer and compared with the measured values. Some conclusions are drawn.
