Stiffness test system microprocessor controlled design
Abstract In the industrial production process, in order to ensure the performance of the instrument, the need for various components of the material for professional elasticity measurement in many technical parameters reflect the material properties, the stiffness of this parameter is the most important. So the size of stiffness determines the properties of materials .In the actual production process of life, a device in a small part, functional differences have stiffness values of the entire system to achieve an enormous impact. So, in terms of functionality and security of a system, the measurement of the stiffness of the technology necessary to carry out research and exploration is critical.
In this paper, the stiffness test method components have been studied, according to the basic principles of the stiffness test, design a complete, portable test system stiffness, select 51 as the main control chip microcontroller system, the microcontroller, based on the use of high-precision sensors data collection, reached a relatively high accuracy, rigidity value by the
microcontroller processes the data and calculates, 12864LCD obtained data show. The system
design has a measurement system is small, light weight, high precision, simple operation, easy to carry. You can work in a variety of environments.
Key words: stiffness single-chip LCD display displacement sensors pressure sensors
