Abstract:
1. An assembling manipulability evaluation apparatus, comprising: an analysis model control unit which disposes at least two component models, which are to be used in assembly of a product to be evaluated, in virtual space displayed on a screen; a virtual operation control unit which moves and operates the component models disposed in the virtual space in accordance with an input operation signal from outside; a model conversion unit which determines contact between the two component models when a relative distance between the models becomes zero and converts the two component models into component analysis models composed of a plurality of mesh-divided elements; a deformed structure analysis unit which determines contact surfaces caused along with assembly of the two component analysis models, executes a structure analysis calculation so that, with respect to movement of the contact surface of one of the component analysis models, the contact surface of another structure analysis model does not penetrate into each other, and obtains deformation, distortion, and a stress of each element and deformation of an entire model; and an evaluation processing unit which searches a maximum deformation stress from among deformation stresses of the mesh constituting a deformed component analysis model, compares the stress with a rupture stress of a component which is set in advance, and performs alert display of rupture of the component when the stress is determined to exceed the rupture stress, and wherein the virtual operation control unit includes:
