The Dynamic Analysis for Special Friction Welder Upsetting System Based on the Finite Element Method

Abstract

Electrolytic aluminium pre-baked anode conductive device for the special friction Welder upsetting system is the research object. Establish dynamic equation of the upsetting system by its Lagrange equation; analyze the key factors affecting the systems dynamic characteristics; build the systems finite element model to be real by ANSYS Workbench; Set key parameters for the two sets of plans and do analysis for the modal and harmonic response successively. The two plans compared results reveals that the guide spacing and the damping among all the parts can affect the systems dynamic characteristics, which will provide a basis for further improvement and optimization of special friction welding machine bed.

Performance Analysis for Spindle System of Special Friction Welder Machine Based on ROMAX Software

“…The spindle of friction welder is a stepped hollow shaft. The simplification is performed when build the spindle model, and the simplified parts are shown as follows: (1). remove the non-critical features, such as screw hole, bolt hole and oil filler hole, etc; (2).…”

“…The special friction welder machine with conductive device made up of aluminum electrolytic prebaked anode is the special welding equipment, which can directly weld the conductive device of aluminum rod guide and the cast steel claw. Besides, this equipment has several significant characteristics: high-quality, high-efficiency, energy-saving, low-consumption, cleaning, etc [1][2]. The spindle system is a key part of the friction welder, which provides the energy for friction welding technology.…”
