Testing the retention of attachments for implant overdentures – validation of an original 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.

Moving Speed

The effect of magnet moving speed on the relaxation of the maximum levitation force of YBCO bulk has been investigated. The experiment was carried out between a cylinder permanent magnet and a single-domain YBCO bulk, and the levitation force was measured using a self-made levitation force measurement system. It is found that the levitation force decreases with time after the gap distance between the magnet and YBCO bulk reduced to 2 mm and kept for the test. It is also found that the levitation force and its relaxation rate is different for different moving speed between the magnet and the YBCO bulk, and the higher the moving speed, the greater the relaxation rate of levitation force. However, the largest levitation force is obtained at an optimal speed, the higher the levitation force, and the faster the relaxation of levitation force.
