Abstract

This paper describes the design and construction of the hydraulic amplification force standard machine of 30 MN (so-called Pascal-type), which will be the biggest force standard machine by hydraulic amplification in the world. The main elements and the most critical components of the machine were expounded, including the hydrostatic support cylinder and the dead-weights groups, which directly affect the system accuracy, and determine the measurement range. The performance of the machine maximises the use value for the user. This machine will play a very important role in promoting the development of high-precision large force metrology technology.

Keywords
