Design of Linear Damper in Calibration Device for Dynamic Force

摘要

The force transducer for dynamic calibration in absorber dynamometer is usually statically calibrated. To solve the problem, a new kind of dynamic calibration device and its working principle is discussed. Furthermore, the principle of its core member, linear damper, is particularly analyzed. Moreover dampers in different structures are discussed in depth and the production of its damping force is deduced. Thus, the theoretical premise of dynamic calibration device and linear damper is provided in this essay.
