Embodiment 1

[0022] refer to figure 1 , shows a flowchart of steps of a method for determining a helicopter moored load according to Embodiment 1 of the present invention.

[0023] The method for determining the moored load of the helicopter in the embodiment of the present invention comprises the following steps:

[0024] Step 101: Determine the equivalent area of ​​each mooring lock based on the length of each mooring lock.

[0025] When the helicopter is docked, multiple mooring locks are required to be attached to its fuselage. There is a mooring lock corresponding to the anchor points on the deck or the ground, and the relationship between the mooring locks and the associated nodes of each mooring lock can be determined through the position coordinates of each mooring point.

[0026] Step 102: Determine the equivalent area of ​​each landing gear.

[0027] When determining the equivalent area, the equivalent area of ​​the landing gear can be determined by the force load of the landi...

Embodiment 2

[0044] refer to figure 2 , shows a flow chart of steps of a method for determining a helicopter moored load according to Embodiment 2 of the present invention.

[0045] The method for determining the moored load of the helicopter in the embodiment of the present invention comprises the following steps:

[0046] Step 201: Determine the equivalent area of ​​each mooring lock based on the length of each mooring lock.

[0047] The method for determining the moored load of the helicopter in the embodiment of the present invention is executed by a computer program preset in the computer.

[0048] When determining the equivalent area of ​​the mooring lock, first determine the length of the elastic body and the length of the rod element of the mooring lock, and substitute the length of the rod element and the length of the elastic body into the preset formula as input to calculate the equivalent area.

[0049] Calculate the equivalent area of ​​the mooring lock according to the fol...

Embodiment 3

[0116] refer to Figure 5 , shows a structural block diagram of a helicopter moored load determination device according to Embodiment 3 of the present invention.

[0117] The helicopter mooring load determining device of the embodiment of the present invention includes: a first area determining module 301, which is used to determine the equivalent area of ​​each mooring lock based on the length of each mooring lock; a second area determining module 302 is used to determine The equivalent area of ​​each landing gear; the load determination module 303 is used to determine the load acting on the center of gravity of the helicopter under various working conditions; The positional relationship of each mooring lock, and the equivalent area of ​​each mooring lock to establish a mooring lock unit; the second unit establishment module 305 is used to establish a positional relationship based on the positional relationship between each landing gear and the helicopter, and the equivalent ...

Abstract

The embodiment of the invention provides a helicopter mooring load determination method and device and electronic equipment. The method comprises: respectively determining an equivalent area of each mooring lock on the basis of length of each mooring lock; determining an equivalent area of each landing gear; determining a load acting on a place of a helicopter gravity center under each working condition; establishing a mooring lock unit on the basis of a position relationship between each mooring lock and the helicopter and the equivalent area of each mooring lock; establishing a landing gearunit on the basis of a position relationship between each landing gear and the helicopter and the equivalent area of each landing gear; constructing a mooring finite-element model on the basis of eachestablished mooring lock unit and each landing gear unit; and respectively using the load acting on the place of the helicopter gravity center under each working condition as an input value to inputthe same into the mooring finite-element model, and outputting a force load of each mooring point under each working condition. Through the helicopter mooring load determination method provided by theembodiment of the invention, a modeling number can be decreased, and computational efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of helicopter moored load calculation, in particular to a method, device and electronic equipment for determining the helicopter moored load. Background technique [0002] When the helicopter is docked on the deck or the apron, it is affected by the sea wind and the movement of the ship. In order to ensure that the helicopter can maintain a stable state and prevent the helicopter from slipping, yawping or even tilting and rolling over, it must be rigged. Tethered to restrict the movement of the helicopter. The mooring load refers to the load on the mooring rigging under the action of wind load and ship motion. The accurate calculation result of the mooring load can provide reliable guidance for the rigging manufacturer on the bearing capacity of the rigging. [0003] The existing method for calculating the load of the mooring lock is as follows: the mature commercial finite element software Patran / Nastran i...
