ABSTRACT
This thesis introduced to have hydraulic pressure to measure the force apparatus relevant background knowledge and deveolp present condition first, and the author design of a simple hydraulic pressure measure force apparatus.
Discussed among them the hydraulic pressure measures the basic priniple of force to apply scope with it and study it of for other measure the good and bad of force point elaborated the total way of thinking of design to measure force to equip choose of each assembly unit, subassembly to use with that hydraulic pressure and the pressure made the superior choice with the oil, and to should equip important assembly unit, subassembly urn body to make a detailed school a pit, and to should measured measure scope and measure accuracy of force apparatus to also make an objective discussion.
End, author piston and urn tube of inside leak question, urn"active area" and pressure gauge of the barrel system measured the influence of the force apparatus measuring value to make meticulous treatise to the hydraulic pressure and made prospect a research.
