Research on elastic modulus measurement system based on STM32

摘要

Elastic modulus, which can be used as the difficulty of material's producing elastic deformation is an important parameter in the engineering application. At present, the method of measuring modulus of elasticity is the original manual measurement. In this text, i want to talk about one method using an embedded processor to measure the elastic modulus automatically. The system uses STM32 as the core, generates a horizontal direction force by controlling the motor, with a tension pressure sensor to measure the tension magnitude, and then the micro deformation of the object under test is obtained by laser ranging. At last, we calculate the elastic modulus by Hooke's law.
