| Abstract: | Using the RAM-SNAP-5000 ultrasonic measurement system and echo method measuring principle,the elastic modulus and Poisson's ratio of a low-carbon steel specimen are measured,the results were in good agreement with the data obtained by tensile tests.The ultrasonic measurement techniques were used to test the elastic modulus and Poisson's ratio of components for certain type of car,and the results were applied to the calculation of car dynamic characteristics. |
