Abstract： |
The double shaft mechanical and electric coupling and loading drive and measurement device is one ferroelectric and piezoelectric material loading and measuring system. The device includes one double shaft self regulating driving unit with fixed loading shaft and self regulating spherical hinge loading shaft, one sealing unit and one electric charge measuring instrument. The double shaft self regulating driving unit can load in both horizontal direction and vertical direction simultaneously in high synchronism and loading precision; the sealing unit ensures no silicone oil leakage; and the electric charge measuring instrument has high measurement precision and overload protection function. The present invention has the features of small size, easy manufacture and high precision. |
