Product Overview

DELMIA Flex Dynamic Cable Simulation provides a highly accurate, physically correct numerical simulation of flexible cables and hoses with circular cross-section for real-time interaction applications. Non-uniform material composition is supported including multi core, shielded or isolated cables; braided or multi layered hoses. Collision detection and contact simulation are enabled, reproducing complex nonlinear behavior of cables/hoses in contact with arbitrary shaped rigid geometry. Arbitrary connections of cables between each other and with rigid geometry are supported. As a result, wiring harnesses with multiple branches can be modeled and tested in real time, allowing for digital mock-ups and enhanced product design.

Cables, wires and hoses play an essential role in the assembly of any industry product. To consider physical cable properties in the digital design phase of a product helps detecting design problems such as those caused by collisions with rigid parts and other compliant parts. It also helps to determine production requirements, such as cable length and the respectively allowed tolerance. This realistic flexible cable analysis significantly reduces the costs for real-life mock-ups.

The behavior of a flexible object is described by the theory of elasticity in terms of several material constants, i.e. Young's module and Poisson's ratio; or Lame coefficients or Bending and torsional stiffness etc. These material properties are related to each other by equivalence formulae. In the case of composite structures, e.g. multilayered cables/hoses corresponding effective constants can be either measured directly in experiments or computed using an additive formulae. Additionally required quantities are the length, external and internal diameters of the cable/hose/layer, volumetric mass density, as well as positions and orientations of the ends of the cable/hose. The theory of elasticity provides equations describing static and dynamical behavior of the flexible object under user interaction. Also various approximate models are known valid in special restricted situations.

The robustness of the implemented scheme has been shown for a variety of realistic situations in interactive design environments. To guarantee the accuracy, the cables, wiring harnesses and hoses have been evaluated intensively. The results of the experimental validations show that shapes of wiring harnesses and hoses computed by DELMIA Flex Dynamic Cable Simulation for Realistic Cable Simulation coincide at high accuracy with experimentally measured shapes. DELMIA Flex Dynamic Cable Simulation solves exact non-linear elastic equations at machine precision, therefore the deviation between DELMIA Dynamic Cable Simulation results and experiment was always on the level of 1% (since the experiments have been carried out with a 1% error). DELMIA Flex Dynamic Cable Simulation is able to provide solution for simulation of cables and hoses combining physical precision and update rate more than 80 fps on a P4 2GHz PC.

Product Key Customer Benefits

Provides physically realistic cable simulation...
The simulation includes the cable properties of length, diameter, density, stiffness and other constraints such as gravity and end clamp locations.

Supports penetration avoidance between cable and obstacles...
The simulation can be setup by the user to specify the objects that the cable may not penetrate. Once this is done, the solver automatically accounts for the cable shape that corresponds to the realistic behaviors during simulation.

Integrated with the DELMIA Device Task Definition product for Robotic applications...
With DELMIA Flex Dynamic Cable Simulation installed and enabled, the DELMIA Device Task Definition application provides an additional toolbar for simulation of cables that are defined for dress up of Robots and other manufacturing resources for validation of cable length, interference and wrapping behaviors during robotic applications.

Supports interactive Jogging motion as well as Task program simulation...
The physically realistic behavior of the cables is automatically enabled during interactive motion by users of the cable ends or obstacles as well as during the running of preprogrammed Task simulations.

Fully compatible with cable models created in CATIA design applications...
Cables designed in CATIA applications such as CATIA Electrical Harness Installation are the starting point for DELMIA simulations based on the designed cable positions, lengths, diameters, and branches.
