AI Technical Summary

Benefits of technology

This technology allows for direct manipulation by visually navigating through 3D models without making them complicated or requiring expensive tools like CAD systems. It also includes an enveloped box with enclosed space inside it, which helps reduce error when transformring from one type into another shape while maintaining its integrity during shipment. Additionally, this system uses a dynamic collision detect technique to ensure proper placement within different environments such as ships' hulls. Overall, these technical features improve the efficiency and effectiveness of sea vessel construction processes.

Problems solved by technology

This patented describes how long delays can occur when transferring objects between different parts within a structure that cannot collide safely due to its complicated shape or space constraints. Current methods for detecting collisional behavior require simulations beforehand, making them time-consuming and expensive.

Embodiment Construction

[0006] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0007] Step 1. Use the C# programming language to create the bounding box of the transport body. The specific process is as follows:

[0008] The first step is to open the 3D model of the transportation equipment and air duct in the Tekla 3D software, and fix the air duct on the lifting platform of the transportation equipment according to the actual use to obtain the 3D model of the transportation body;

[0009] The second step is to use C# to carry out secondary development of data extraction on Tekla software. In the global coordinate system of Tekla software, obtain the 3D coordinate with the largest value among all points in the physical space of the 3D model of the transport body Obtain the 3D coordinate with the smallest value among all points in the solid space of the 3D model of the transport body The superscript 1 indicates the thre

Abstract

The invention discloses a dynamic collision detection method for the transportation process of an internal air duct of an ocean platform, which comprises the following steps: fixing an air duct and transportation equipment into a transportation body, respectively creating bounding boxes for the transportation body and an ocean platform, and controlling the transportation body bounding box to move in an ocean platform bounding box, In the moving process, whether the boundary curve of the transport body bounding box intersects with the boundary curve of the ocean platform bounding box or not is calculated, If yes, the moving curve equation is modified until a non-intersecting moving curve equation is obtained. The air duct transportation efficiency can be improved, the air duct transportation safety is guaranteed, and the adaptability to the complex environment of the ocean platform is improved.
