Abstract: the development and production of the three direction six force dynamic (Fx.Fy.Fz.Mx.My.Mz) sensor is the test of the seismic dynamic mechanical properties of the majority of the teachers and scientific and technical personnel to test the three direction force of the test model structure bearing or the node in the process of the continuous introduction and localization of the seismic simulation shaking table in our universities and scientific research institutes. At the historic moment, the seismological shaking table of Tongji University has been introduced in the early 80s of last century, in the decades since the introduction of the United States MTS company in the early 80s, especially after the extension of three to six degrees of freedom and after the introduction of a series of full set of seismic analog shaking table array products in the Jiading campus, the more dynamic value parameters of the three to six Division. To more attention, and is an indispensable key test of the sensor, the measured data in the test and analysis of seismic structure, will play a very important role.

In this paper, the development process of the three to six force dynamic sensor is developed. From the design scheme, the selection of material, processing and manufacturing process, the selection of sensitive elements and the sealing of moisture proof seal are carefully made. The calibration of the product factory, especially the calibration method for the three direction force sensor, is made. The combined calibration method and application examples and the future calibration of the three to six dynamic sensor are proposed, which can be used for reference to the seismic test researchers of the dynamic sensor with three to six division force, and also for the National Institute of measurement and detection, and the dynamic sensor of three to six forces is developed. Calibration specifications or regulations for scientific and technical personnel reference use!

 

Key words: three direction six component dynamic sensor, earthquake simulation shaking table (array), structural seismic test
