Dimensional Chain Calculation and Tolerance Analysis

Focusing on the front end of product design, precision planning and virtual validation are carried out simultaneously based on 3DCC 3D dimensional chain calculation and tolerance analysis software. It supports direct reading of original files from mainstream CAD platforms such as CATIA and UG, with automatic recognition of PMI information and mapping to the simulation environment, eliminating repetitive modeling steps.

Core calculations are based on the Monte Carlo algorithm. Through tens of thousands of virtual assembly iterations, it simulates dimensional variation patterns under actual working conditions, with simulation accuracy consistently above 95%. The built-in AI intelligent annotation module can automatically generate key tolerance recommendations, and deep learning algorithms automatically construct assembly constraints based on model features, significantly reducing human trial-and-error costs. The software supports dual-track parallel operation of virtual point modeling and MBD, flexibly adapting to rapid validation needs in the early concept stage of products.

Analysis outputs include contribution ranking, tolerance zone distribution charts, and CPK achievement rate assessment, supplemented by dual verification using the extreme value method and statistical method. Designers can use these to precisely locate tolerance-sensitive links and relax non-critical tolerances while ensuring assembly function, achieving the optimal balance between quality and cost.
