Abstract

The invention discloses a physical simulation test device for linear friction welding, which is used for solving the technical problem that a conventional linear friction welding device can not detect welding performances in a real-time manner. The technical scheme is as follows: the physical simulation test device for linear friction welding comprises three major parts, namely a pressurizing mechanism, a linear reciprocating motion mechanism and a visible clamp, and a friction interface, as well as flow pattern of nearby plastic metal and temperature distribution, can be recorded and detected by a high-speed video camera and an infrared thermodetector through the visible clamp in a real-time manner.

Description

technical field [0001] The invention relates to a simulation test device, in particular to a linear friction welding physical simulation test device. Background technique [0002] During the linear friction welding process, the plastic metal flow behavior, temperature field distribution, and heat energy transfer and dissipation rules at the joint interface will have an important impact on the quality of the welded joint. If the above plastic metal flow behavior, temperature field distribution and heat energy transfer and dissipation laws can be obtained, it will help to control the quality of linear friction welded joints. [0003] refer to image 3 . The known linear friction welding device is composed of three parts: a linear reciprocating mechanism, a pressurizing mechanism and a weldment fixture. The driver 18 drives the weldment 32 fixed on the vibrating plate 13 by the lower fixture 33 through the rocker 17, and makes a linear reciprocating motion left and right alon...
