Overview of ASM5.0: ASM5.0 automatic stress detector is a high-performance product developed by Chaowen Company.Three channels of static strain and 1 point stress or residual stress can be measured.Strain collection, storage, printing as a whole, strain gauge used by the A / D CPU, memory, communications and other chips, as well as bridge matching precision resistors are selected from the world's top manufacturers of electronic devices,Both the schematic design and the layout and wiring of components on the circuit board have fully considered the effects of temperature, humidity, vibration and other factors, as well as electromagnetic interference such as static electricity, pulse group, electromagnetic radiation, etc., so the measurement accuracy is high and the linearity is good.Small temperature drift, can work safely and reliably for a long time, can be widely used in industrial field, enterprise R & D test center, university teaching experiment strain, stress test. Main functions of ASM 5.0: 1.Automatic switching, time-sharing measurement of three static strain. 2.Elastic modulus can be set to measure the static stress of various materials. 3.The residual stress (σ _ 1, σ _ 2, θ _ n) can be recorded by eliminating the effect of additional strain on drilling, automatically detecting, calculating accurately, and displaying on the LCD screen the residual stress (σ _ 1, σ _ 2, θ _ n). 4.The blind hole release coefficient can be calculated automatically.It is not only suitable for materials with known strain release coefficient Anb by blind hole method, but also for materials with unknown strain release coefficient by blind hole method, which can be converted into more accurate coefficients by relevant theoretical formulas, and residual stress can be measured.In fact, a large number of tested materials are unknown, inconvenient or uncalibrated.The calculation results of residual stress will be completely wrong if we do not take into account the large differences between different materials.Because the strain release coefficient of different materials may be very different, the automatic residual stress detector is very convenient and accurate for measuring the residual stress of the unknown material AZB. 5.Embedded printer, on-line printing results, such as: principal stress σ 1, σ 2 and principal stress direction θ. 6.Strain gauge sensitivity can be set. 7.Poisson ratio, release coefficient and so on can be set. 8.Mass storage of measurement results, and easy to list, query, print. 9.The device operation interface adopts drop-down menu, various options and material parameters of workpiece input or query is extremely convenient. ASM5.0 Application field: 1 . Mechanical engineering and manufacturing equipment . 2 . Transportation equipment such as high - speed rail , automobile and ship . 3 . Power and power engineering . 4 . Bridges and roads . 5 . Metallurgy , petroleum and chemical industry .
