With continuous growth and stringent demand for weight reduction in automotive structures, the automotive industry has shown an increasing interest in dissimilar aluminium–steel welding. Dissimilar lap joint between AA6351 alloys of 2 mm thickness and DP800 advanced high-strength dual-phase steel of 1 mm thickness has been attempted and joined successfully by friction stir welding with different combinations...
This paper proposes a structural design and multi-objective optimization of a two-degree-of-freedom (DOF) monolithic mechanism. The mechanism is designed based on compliant mechanism with flexure hinge and is compact in size (126 mm by 107 mm). Unlike traditional one-lever mechanisms, a new double-lever mechanism is developed to increase the working travel amplification ratio of the monolithic mechanism...
