Theoretical studies of processes and apparatus for ultrasonic ring welding of thermoplastic materials

摘要

The article is devoted to the discussion of the results of theoretical investigations of joining of polymeric materials by ultrasonic welding seam made by the ring-shaped working tool. According to results of theoretical studies optimal parameters are established according to the energy influence depending on the diameter and the width of formed weld. The theoretical results are allowed to propose an algorithm of optimal control of ultrasonic welding of thermoplastic materials in formation of circular welds of large diameter and to realize a new approach to the design and selection of specialized ultrasonic equipment.
