This study focuses on the performance characteristics of 7075 aluminum alloy integrated die-cast body connection joints under dynamic loads, and analyzes the response behavior of the connection joints under different load conditions through experiments. High-precision testing equipment is used to simulate dynamic loads in actual working conditions, aiming to reveal the mechanical properties and durability of 7075 aluminum alloy die-cast joints. The experimental results show that the aluminum alloy integrated die-cast joints exhibit good strength and toughness under dynamic loads, but there is also a certain risk of fatigue damage. This research provides an important reference for the automotive industry in material selection and optimization of connection technologies, and offers experimental basis for the design of subsequent related products.
