CAE Software introduction

CAE software can be categorized by research type into static structural analysis and dynamic analysis; by problem type into linear and nonlinear problems; and by physical field into structural (solid), fluid, and electromagnetic analyses.

Major CAE Software Overview

• HyperWorks: Primarily for pre-processing (meshing, loading, constraints) and post-processing (results visualization).

• I-DEAS: Combines CAD and CAE capabilities.

• SolidWorks Simulation & Motion: Leverages SolidWorks’ robust features for simulation and motion analysis.

• TSV: General-purpose pre-/post-processing software.

Key Features of SolidWorks Simulation

Seamless Integration with SolidWorks

• Automatically utilizes SolidWorks assembly components and mates without redefinition.

• Unified environment for motion tools (SolidWorks Motion, physical simulation, assembly motion).

• Transfers material properties defined in SolidWorks.

• Easily replicates studies to explore multiple motion scenarios.

Advanced Motion Analysis

• Generates compound joints (hinges, screws, spherical/cylindrical/planar joints, universal couplings).

• Controls acceleration/velocity with pure forward forces.

• Applies constant, spline, or step functions to motors/forces.

• Switches motors on/off during motion and compresses/releases mates for part positioning.

• Creates motion couplers (gears) for power transmission.

• Defines linear/nonlinear springs for flexible connections.

• Models 3D contact (static/dynamic friction) for part interactions.

• Incorporates damping to reduce vibration amplitudes.

Visualization & Results Interpretation

• Plots XY graphs for numerical data over simulation cycles.

• Displays displacement, velocity, acceleration, and force vectors at joints.

• Tracks trajectories of arbitrary points and generates reference curves on parts.

• Detects collisions during assembly motion.

• Exports motion to AVI or eDrawings® for sharing.

• Generates Microsoft® Excel charts in any coordinate system.

Design Comparison & Optimization

• Evaluates stress, strain, and displacement in parts/assemblies.

• Uses parametric inputs (materials, loads, geometry) for analysis.

• Automates design scenarios to compare alternatives.

• Drag-and-drop functionality for study creation/copying.

• Includes a library of 200+ materials or supports custom materials.

Assembly & Connection Simulation

• Automatically meshes large assemblies and multi-body parts.

• Joins parts with gaps without modifying the assembly.

• Simulates connections (pins, springs, bolts, bearings, spot welds).

• Analyzes stress from interference fits.

• Identifies contact forces/stresses in real-world operating conditions.

Load & Constraint Application

• Applies forces, pressures, moments, and bearing loads.

• Transfers remote loads to parts/assemblies.

• Simulates gravity and centrifugal forces.

• Applies fixed/directional constraints or prescribed displacements.

• Models flexible supports.

Advanced Analysis Tools

• Modal Analysis: Avoids resonance and designs vibration isolation systems.

• Thermal Analysis: Studies conduction, convection, radiation; supports isotropic/orthotropic materials.

• Drop Test Simulation: Evaluates impact resistance and post-collision interactions.

• Optimization: Automatically determines optimal designs based on constraints (static, thermal, frequency, buckling).

• Fatigue Analysis: Predicts lifespan and identifies design improvements.

• Pressure Vessel Analysis: Combines static/thermal/seismic loads per ASME standards.

Specialized Modules in SolidWorks Simulation Premium

• Nonlinear Analysis: Large deformations, hyperelastic materials (rubber, silicone), plasticity, creep.

• Dynamic Analysis: Time-history response, random vibration (PSD input), RMS/PSD results.

• Composite Analysis: Multi-layer shells (isotropic/orthotropic), sandwich structures (honeycomb, carbon fiber).

CAE Adoption in China

While CAE is widely recognized, its adoption lags behind Europe and America due to:

• High software costs.

• Steep learning curves requiring specialized expertise.
