Abstract

The present invention provides a ten-thousand-ton force standard machine which comprises a rack, a ten-thousand-ton force application source, a parallel type standard sensor unit and a reaction frame, wherein the parallel type standard sensor unit comprises a first-layer partial pressure unit, a second-layer partial pressure unit, nine ten-thousand-ton standard sensors and a chassis, which are sequentially arranged from top to bottom; wherein the nine kiloton standard sensors are arranged on the chassis in parallel. The machine has the two layers of voltage dividing units, wherein each voltage divider adopts a three-supporting-leg voltage dividing mode, so that according to the three-point balance principle, it can be ensured that each supporting leg is stressed in a balanced mode, force is stably transmitted to all kiloton standard sensors connected in parallel at the bottom, and the force measuring accuracy is improved; that is, by means of the kiloton standard sensors meeting the measurement precision requirement, the verification of the 10000-ton force meeting the measurement precision requirement is realized through the parallel arrangement form of the multiple kiloton standard sensors, and the global technical blank in the field of 10000-ton force standard machines is filled.

Description

technical field [0001] The invention relates to the technical field of force value verification, in particular to a 10,000-ton force standard machine. Background technique [0002] Standard force measuring machines are mainly divided into lever machines, dead weight machines and superimposed force standard machines according to the basic principles. Since both lever machines and dead weight machines use weights as the force source, for super large As far as the force measuring machine is concerned, if the gravity of the weight is used as the standard load, the weight must be very large and the loading is very difficult. Therefore, superimposed force standard machines are usually used for super-large force measuring machines. The superimposed force standard machine uses a hydraulic or mechanical force generator as the force source, and the force value is measured by a standard sensor. The standard sensor needs to be verified on a higher-level dynamometer, and its mechanical ...
