Problems solved by technology

[0002] Traditional CAD software (such as Pro / E, SolidWorks) can be used to make assembly simulation of mechanical parts, but they have the following problems: First, when CAD software performs assembly simulation on mechanical products, it is only a form of animation, The human-computer interaction is poor; the second is that during the assembly simulation of the CAD software, when the dimensions of the two parts do not meet the tolerance range, the assembly can still be carried out, resulting in penetration, which does not meet the assembly requirements in actual production of

Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0029] see figure 1 , a construction method of a collision detection system, the present invention takes the collision detection between the main shaft and the pulley of the CNC lathe headstock as an example, and describes the implementation process of the present invention in detail, including the following steps:

[0030] step one:

[0031] Create a 3D model of the CNC lathe headstock in SolidWorks, and import the built 3D model into EON Professional, the software will automatically assign part nodes to each part of the CNC lathe headstock;

[0032] Step two:

[0033] Set the automatic assembly of the spindle box. This process mainly uses the Place node. Drag the Place node to each part node, double-click the node, and set the part along the X-axis or Y-axis during the automatic assembly process in the pop-up property window. Or the dista...

Abstract

The invention discloses a construction method for a collision detection system. The method comprises: firstly, establishing a three-dimensional model of a mechanical part in SolidWorks, and importing the established three-dimensional model into virtual reality software EON Professional; secondly, finishing automatic assembly of parts of the mechanical part by utilizing a 2DText node and a Place node of the software EON Professional; and finally, finishing collision detection of the parts of the mechanical part and detecting collision response during collision by utilizing a CollisionObject node, a Material2 node, a DirectSound node and a Colors element of the software EON Professional. The construction method for the collision detection system can effectively eliminate the penetration phenomenon of existing CAD software in an assembly simulation process of mechanical products, enables a user to feel response when penetration occurs to two parts from visual and hearing perspectives, and has the characteristics of easiness for operation, high authenticity and remarkable effect.

Description

technical field [0001] The invention relates to the technical field of virtual reality and system simulation, in particular to a construction method of a collision detection system. Background technique [0002] Traditional CAD software (such as Pro / E, SolidWorks) can be used to make assembly simulation of mechanical parts, but they have the following problems: First, when CAD software performs assembly simulation on mechanical products, it is only a form of animation, The human-computer interaction is poor; the second is that during the assembly simulation of the CAD software, when the dimensions of the two parts do not meet the tolerance range, the assembly can still be carried out, resulting in penetration, which does not meet the assembly requirements in actual production of. [0003] Collision detection is a key technology of virtual assembly technology. The essence of collision detection is to detect whether two or more objects occupy the same space area in the virtu...
