Fabrication of a Three-dimensional Force Measurement System Using Double Series Magnetic Suspension

In low pressure turbine stages, adjacent blades are coupled to each other at their tip by covers, called shrouds. Three-dimensional periodic contact forces at shrouds strongly affect the blade vibration level as energy is dissipated by friction. To validate contact models developed for the prediction of nonlinear forced response of shrouded blades, direct contact force measurement during dynamic tests is mandatory. In case of shrouded blades, the existing unidirectional and bi-directional contact force measurement methods need to be improved and extended to a tri-directional measurement of shroud contact forces for a comprehensive and more reliable validation of the shroud contact models. This demands an accurate and robust measurement solution that is compatible with the nature and orientation of the contact forces at blade shrouds. This study presents a cost effective and adaptable tri-directional force measurement system to measure static and dynamic contact forces simultaneously in three directions at blade shrouds during forced response tests. The system is based on three orthogonal force transducers connected to a reference block that will eventually be put in contact with the blade shroud in the test rig. A calibration process is outlined to define a decoupling matrix and its subsequent validation is demonstrated in order to evaluate the effectiveness of the measurement system to measure the actual contact forces acting on the contact.

Force Measurement System

According to the requirements of measurement of plantar pressure and shear stress in the meantime, this thesis puts forward a plan to construct a new insole plantar pressure and shear stress system based on multifunction data acquisition modular and Lab VIEW. Then the hardware part and software part are designed and developed respectively. There are 3 sensors are arrayed at each measurement point, that means 3 sensors are assembled in 3 different directions of X,Y and Z . The piezoelectric ceramic type sensors are designed, manufactured and calibrated according to scientific methods. Meanwhile, the DAQ card is selected carefully. Of course, the software part is developed based on Lab VIEW. A series of tests are performed in order to validate the function of the measurement system. The results satisfy the anticipated design requirements. At last, the problems and application trend of the measurement system are predicted.
