Stability Analysis
In early design phases, the robustness of the design and assembly concept can be analyzed and evaluated using stability analysis. The stability analysis determines the geometrical sensitivity due to position of locators. Locator positions can be manually or automatically optimized with respect to critical areas or overall sensitivity.
Statistical Variation Simulation
RD&T is using Monte Carlo simulation to statistically analyze variation, capturing all 3D effects and interactions for complex assemblies. RD&T has an integrated FEA (Finite Element Analysis) solver that allows non-rigid analysis. The effect of variation can then be analyzed for assemblies with sheet metal or plastic parts that bend or deforms during assembly. This module also allows assembly, welding and clamping order to be analyzed and optimized to minimize variation.
High-end Visualization
In the RD&T show-room, variation effects can be visualized with high degree of realism by adding lightning, shadows, textures and material properties. RD&T has also interface to some of the leading visualization software packages on the market. The visual sensitivity of the product can then be judged with respect to geometrical variation long before production takes place and unnecessary late changes can be avoided.
Geometry Assurance Process
and Documentation
RD&T supports a geometry process, from early requirement definition, through locator optimization, variation analysis, matching and trimming, with all engineering documentation and drawings. The process is generic and suitable for a variety of industries producing physical products.
