Abstract： For the instrument panel beams made mainly of steel， aluminum-magnesium alloy， and composite material， this paper compares the instrument board beams of different processes in terms of lightweight， accuracy， and cost， studies and analyzes the use scenarios and application trends of instrument panel board， and compares the technical defects and process restrictions of different types of instrument panel beams. The study believes that with the general use of composite material beams， the cost advantage of steel beams and the lightweight advantages of aluminum-magnesium alloy beams will no longer be significant， while composite material beams will become the mainstream trend of process manufacturing.

Key words： Instrument panel beam， Accuracy， Lightweight
