Preparation of 50 kN Specialized Standard Force Device at CQMQ

摘要

The Specialized Standard Force Device (in short: SSFD) was designed to keep the metrology of the working dynamometers (300N~50kN). The push-pull gauge (digital display type and pointer type) (in short: PP) and tension-meter were the main measurement objects. The working principle of the SSFD was introduced in the paper. It was a build-up type system, innovative designs have been applied: the 1st, the precision angle changing mechanism has been developed to study the affection of the loading direction; the 2nd, the fixture system has been designed to assemble and disassemble working dynamometers conveniently and efficiently; the 3rd, the specified arrangement was adopted to control the movement of the movable beam. The machine was designed to apply the force up to 50kN in compression direction and pull direction respectively.
