Abstract

The dynamic and static characteristics of mechanical systems are closely related to the interface contact state. The accurate measurement of interface contact state has become a key scientific problem in the design and control of dynamic and static characteristics of mechanical systems. Ultrasonic detection technology can realize the measurement of contact state, and the accurate measurement of reflection coefficient is the key of this technology. Therefore, this paper carries out theoretical research on the ultrasonic measurement technology of multi-point contact state of ultrasonic lateral waves, studies the influence law of ultrasonic reflection and refraction effect at the interface on the critical lateral waves, builds a multi-point reflection coefficient analysis model, and obtains the true reflection coefficient and measurement error of each measuring point.The theoretical research will provide theoretical support for the accurate measurement of the interface contact state, and has important significance for the reliable design, stiffness optimization and vibration suppression of equipment in aviation, aerospace, Marine and manufacturing fields.
