Problems solved by technology

At present, the research on the transportation of wind power equipment involves optimizing the transportation road process through CAD technology. Although this method optimizes the sweeping trajectory, it does not simulate the trajectory of the wind turbine blades carefully.
AutoTURN is also used to optimize road plane parameters for wind farms. AutoTURN can efficiently display the trajectory of wind turbine components passing through curves, but fails to show the collision between wind turbine blades and obstacles outside the road.

Embodiment 1

[0074] Taking a wind power project in a certain city and county in a certain province as the research object, the numerical simulation model is used to analyze the state of wind power road transportation. The algorithm is implemented in Java, and the operating environment is Microsoft Windows 10 operating system, AMD Ryzen 73700X 8-Core Processor (3600MHz) processor, and 32G memory.

[0075] Before numerical simulation, the parameters of each component need to be determined, and the component parameters are as follows:

[0076] 1) 3D terrain parameters

[0077] The road and terrain data are collected by UAV aerial survey technology. The UAV uses DJI Matrice 300RTK, the working frequency is 2.40-2.48GHz and 5.72-5.85GHz, the flying height is 100m, and the speed is 23m / s. The lidar adopts Hesai Pandar40P, with a single echo point frequency of 720,000 points / s and a double echo point frequency of 1,440,000 points / s. In this paper, the ground-like dual-segment flight mode is use...

Abstract

The invention relates to the technical field of road transportation information, in particular to a method for numerical collision experimental simulation for wind power equipment transportation. According to the method, a method for simulating a motion form of a fan component on a transportation road by using a numerical value is provided, so that a numerical collision test model is constructed. The invention provides a quick and effective tool for solving the problem of barrier-free turning of large equipment during transportation of fan equipment. According to the method, a point cloud boundary scanning method is further provided, collision points are searched through a relative difference model, and finally, the specific position and the square quantity of collision between the fan equipment and the obstacle are calculated through three-dimensional application of Riemann-Stetigersi integral. And an effective reference basis is provided for formulating an obstacle removing scheme when obstacles are encountered during large piece transportation.

Description

technical field [0001] The invention relates to the technical field of road transportation information, in particular to a method for numerical collision experiment simulation for wind power equipment transportation. Background technique [0002] Wind power equipment transportation is a difficult point in wind power projects. Numerical collision simulation for wind power equipment transportation is an important non-engineering measure to improve transportation efficiency in road transportation. At present, the research on the transportation of wind power equipment involves optimizing the transportation road process through CAD technology. Although this method optimizes the sweeping trajectory, it does not simulate the trajectory of the wind turbine blades carefully. AutoTURN is also used to optimize road plane parameters for wind farms. AutoTURN can efficiently display the trajectory of wind turbine components passing through curves, but it cannot show the collision between ...
