COMPUTER-IMPLEMENTED METHOD FOR DEFINING INITIAL CONDITIONS FOR DYNAMIC SIMULATION OF AN ASSEMBLY OF OBJECTS IN A THREE-DIMENSIONAL SCENE OF A SYSTEM OF COMPUTER-AIDED DESIGN

摘要

A computer-implemented method for defining initial conditions for dynamic simulation of an assembly of objects in a three-dimensional scene of a computer-aided design system comprises the steps of: providing an assembly of objects with information on kinematic joints linking objects of the assembly (S1); providing a manipulating tool (M) embedded in the scene, the manipulating tool comprising a three-axes referential allowing a degree of freedom in translation and a degree of freedom in rotation with respect to each axis (S2); attaching the manipulating tool (M) to one object of the assembly (S3); selecting a degree of freedom of the manipulating tool (M) attached to the object of the assembly (S4); inputting at least one initial condition (IC) according to the selected degree of freedom, wherein an initial condition comprises an initial position and/or an initial speed and/or an initial acceleration (S5); and calculating and displaying in real time dynamic simulation taking into account the initial conditions (IC) previously defined (S6).
