Reported by China Instrument Industry Association

Recently , the China Instrument and Apparatus Industry Association presented and reported the excellent results of the China Machine Test . China Instrument Industry Association is a national, industry-based, non-profit social organization that gathers many leading and well-known enterprises and research institutes in the industry. Over the years, it has fully played the role of bridge and link between government departments and member units, and has done a lot of work to promote the development of the instrumentation industry and played an irreplaceable role.

The CBY KL12-2.4 air-cooled high-temperature dynamic extensometer and in-situ test instrument for high-temperature and high-frequency material mechanical properties were introduced in detail in the special report of the China-machine test . The details are as follows.

Product introduction

The high-temperature dynamic extensometer is the core measurement component of the high-end material mechanical property testing system under high-temperature and ultra-high-temperature service conditions. Due to its advanced technology and complicated manufacturing process, it has been mainly imported for a long time, and the price is extremely expensive. This product overcomes the technical problem of strain measurement under ultra-high temperature service conditions, and solves the “stuck neck” problem that high-end mechanical testing systems have long relied on imports under high-temperature and ultra-high temperature service conditions, and can replace imports. It has been used by AECC Beijing Aeronautical Materials Research Institute, National Testing Machine Quality Inspection and Testing Center and other research institutions.

Product introduction

The test and research on the mechanical properties of materials under complex loads is an important support for the performance test guarantee of key materials in many fields such as aerospace. The research is highly dependent on advanced testing techniques and instruments. This project relies on the major scientific instrument and equipment development project in the national key research and development plan to carry out technical research, and solves the mechanical behavior of materials, deformation and damage mechanisms and their correlation with high temperature, complex static and dynamic mechanical loads under near-actual working conditions for many fields such as aerospace. The scientific problem of the correlation law between complex load action and material properties provides innovative technical means.
