Abstract

An analysis for an impact system is presented. The results are then used to interpret the test data from dynamic separation of resistance spot welded joints. In this Part I of the investigation emphasis is placed on the design consideration, development of a test system and verification of the design from actual test data obtained from the test system. In addition, the inertia effect of a generic dynamic system is analyzed using the principle of rigid body dynamics. It is shown that the load recorded by a load cell could include both the load experienced by the test specimen and the inertia force generated from the mass and acceleration between the specimen and the load cell, when the load cell is placed on the fixed side of the test specimen. Impact fixtures designed for spot weld strength testing are then studied for the inertia effect.
