Aluminium profile extrusion can quickly design and manufacture structural frames. However, the structural integrity of such components can be significantly improved through various design considerations and analysis. This article shares three tips for creating industrial-grade, rigid and reliable T-slot aluminum extrusion structures.
As we all know, aluminum profiles can quickly design and manufacture structural frames, that is, the overall structural integrity of such components can be significantly improved through various design considerations and analysis. The following are the three main design tips for creating an industrial-grade, rigid and reliable t-slot aluminum extrusion structure.
Choose the correct aluminium profile extrusion
All the created extrusion profiles are not equal. The stiffness of profiles with similar external dimensions (for example, 45 mm x 45 mm) can vary significantly based on their moment of inertia, with certain profile geometries leading to a 40% increase in beam stiffness. The other is the cross-sectional area, which directly affects the overall weight of the component.
To determine whether the profile meets your design requirements, first estimate the applied load on the structure through free body diagrams and basic static calculations, and then estimate each individual stretch. Once determined, calculate the maximum deflection and bending stress of each critical extrusion according to your application. Comparing the maximum bending stress with the corresponding yield strength of the material, the approximate magnitude of the ability of the extruded part to withstand the required load can be derived.
Carefully select the extrusion joint configuration
Choosing the right extruded profile is only part of the work required to propose an effective structure. The assembly joint configuration can also substantially change the rigidity and structural integrity of the design. Avoid assembly joints relying solely on friction to support the load. One extrudate can be placed on another extrudate. Then, the assembly board fixes all the parts together, but can only bear the minimum force.
Use high-strength extrusion systems for demanding applications
Combining effective assembly joints with appropriate extrusion profiles can definitely improve the structural integrity of the assembly. The two main benefits of locking the boss in the extrusion groove are:
Since the plate is no longer positioned by the loose clearance hole of the screw, the angular deviation can be eliminated.
By converting friction joints into structurally constrained joints, the sliding resistance can be increased.
The aluminium profile extrusion structure has become a real alternative to welded steel structures in many applications. In order to create an effective aluminum frame, some design guidelines must be considered.
