Design of Ultrasonic Wave Velocity System for Intensity of Laminated Veneer Lumber Based on AVR Microcontroller

Abstract:

This paper does research in the independent development detection system for intensity of laminated veneer lumber via ultrasonic wave. By measuring the velocity of ultrasonic wave and other parameters on-line, the dynamic elastic modulus of laminated veneer lumber can be calculated through AVR as the data processing core of this system. And because of the dynamic elastic modulus showed positive correlation in plank strength, the timber grade can be divided through this system.
