英文摘要：

Through in-depth analysis of the operational principles of a linear friction welding machine, a controlling system based on Labview is designed and implemented. The major characteristics of this controlling system is that a mixed controlling mode is applied, which combines the time controlling mode and the deformation controlling mode. The new mode can overcome the ＂simple control＂ which is the shortage of the pre-existing controlling methods. The practical application shows that the controlling system works well and meets the requirements of the welding technology, with great value in engineering application.
