What happens when the dynamometer produces an error?
Dynamometer testing is very important push pull dynamometer, a dynamometer many users dynamometer performance requirements more refined product, and thus the structure and design for an extremely precise appearance, and the error is determined and the precision of assembly The value requires the control to be regulated, and the cause of the following dynamometer error should be properly handled to improve the accuracy of the product. Today Xiao Bian shares with everyone the reasons for the error in the dynamometer: First, manufacturing error Manufacturing error, also known as process error, is mainly produced in the manufacturing process of parts, such as differences in the properties of parts and materials, the errors caused by the inaccuracy of the size and shape of parts in manufacturing and installation, and manufacturing errors are random errors. When calculating the total error, it is often assumed that the error is normally distributed, so it can be added geometrically. Second, the use of error Use errors occur during the use of the part. Such as parts of the wear surface, deformation under load, changes in the size of the environment caused by changes in parts and vibration, friction and other causes of error. The use error is also a random error, and the calculation method is the same as the manufacturing error. Third, the design error The design error is also called the principle error. It is mainly generated during the design process. For example, the approximate mechanism is used instead of the ideal mechanism in the design of the scheme, or the approximate assumption is adopted. This causes the design to have an error in principle at the beginning. Design errors are systematic errors that should be algebraically summed to calculate the total error. Fourth, the parts of the error and accuracy Accuracy is an important indicator for measuring the performance and quality of dynamometer products. Therefore, when designing digital force measurement timing, the accuracy of dynamometer products should be analyzed and calculated, and the accuracy of the various components that make up the product should be specified. Accuracy, also called degree, refers to the closeness of the actual parameter values ​​(size, geometry, etc.) to the nominal value; the error refers to the difference between the actual parameter value and the nominal value. The smaller the error, the higher the precision, and the cost. The higher it is. The above four points gave us a detailed introduction to the causes of errors in the dynamometer. I believe many people have seen some of the dynamometers after reading this article. The production of the Chinese dynamometer industry started from the 1970s and has now gone through more than 20 years. With the development of China's economy, the force measuring instrument industry has made great progress. In 2002, it provided hundreds of thousands of steel dynamometers and several million aluminum dynamometers for the Chinese instrumentation industry. Modernization has made great contributions. Polyester Spunbond Non-woven Fabric Production Line PET polyester non-woven fabric equipment mainly includes: polyester filament non-woven fabric machinery, polyester staple non-woven fabric machinery. The produced non-woven fabric has the characteristics of high strength, high temperature resistance (can be used in 150 ℃ environment for a long time), aging resistance, ultraviolet resistance, high elongation, good stability and permeability, corrosion resistance, sound insulation, mothproof, non-toxic, etc. In addition, there is a very special physical property: anti gamma ray. The surface is smooth and glossy. It has excellent physical and mechanical properties in a wide temperature range. Its long-term use temperature can reach 120 ℃, and its electrical insulation is excellent. Even under high temperature and high frequency, its electrical performance is still good, but its corona resistance is poor, creep resistance, fatigue resistance, friction resistance, and dimensional stability are good.
