Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is flow chart of the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The embodiment of the invention provides a kind of methods of optimization transmission of electricity steel pole construction weight, comprising the following steps:
Step 1, the power and torque at steel pole component both ends to be optimized are determined；
Step 2, according to the size and steel strength design value of steel pole force in member and torque, it is minimum to find out steel pole Component Theory
Sectional area；
Step 3, theory is found out according to steel pole component torque and steel strength design value and " Designing Steel Tube Pole technical stipulation "
Minimum bending resistance section factor；
Step 4, it is provided automatically according to theoretical minimum bending resistance section factor, " Designing Steel Tube Pole technical stipulation " and sectional area excellent
Required cross section parameter value range when change, and open and carry out numerical value adjustment to user；
Step 5, it using the thickness of steel pole component as benchmark variable quantity, is calculated in range according to the known quantity that previous step obtains
The corresponding practical minimum sectional area of thickness value, optimization are completed.
In the present embodiment, the power and torque at the step 1 steel pole component both ends take the power and moment values of biggish one end.
In the present embodiment, steel pole Component Theory smallest cross-sectional product value=steel pole component axle power/stress design of the step 2
Value.
In the present embodiment, the minimum bending resistance section factor=moment of flexure/stress design value of the theory of the step 3.
In the present embodiment, when the step 4 provides cross section parameter value range required when optimization automatically, steel pole component is cut
Area=3.14* diameter * thickness, bending resistance section factor=0.393* diameter3* thickness/(0.5* diameter)=0.787* diameter2* thick
Degree, radius-thickness ratio are not more than 38060/ stress design value, and thickness minimum value is not less than 4mm, and maximum is not more than 100mm.
A specific embodiment is given below and illustrates Method And Principle of the invention:
If component to be optimized: 107.5 thousand Ns of axle power, 2,150,000 Ns of rice of moment of flexure, steel Q235 used, annular.
Step 1, the power and torque at component both ends to be optimized are determined, generally, because component both ends are strong, torque,
It when calculating, is only maximized, it is safe to guarantee that it is used；
Step 2, Component Theory minimum sectional area is found out according to the size of power and steel strength design value, because component is
Q235, therefore stress design value is 215 Ns every square millimeter, because axle power is 107.5 thousand Ns, therefore theoretical minimum sectional area just should be
107.5*1000/215=500 square millimeter；
Step 3, theoretical minimum bending resistance is found out according to torque and steel strength design value and " Designing Steel Tube Pole technical stipulation "
Section factor；It is obtained according to direct stress=moment of flexure/bending resistance section factor: the minimum bending resistance section of moment of flexure/stress design value=theory
Coefficient=2150*1000*1000/215=10,000,000 cubic millimeters
Step 4, required when providing optimization automatically according to bending resistance section factor, " Designing Steel Tube Pole technical stipulation " and sectional area
Cross section parameter value range, and open user is given to carry out numerical value adjustment；Cause:
Minimum sectional area=3.14* diameter * thickness (theoretical value)
Bending resistance section factor=0.393* diameter3* thickness/(0.5* diameter)=0.787* diameter2* thickness (theoretical value)
Radius-thickness ratio is no more than 38060/ strength failure criterion (normal value requirement, can be changed)
Thickness minimum value requires to be not less than 4mm, and maximum is not more than 100mm (normal value requirement)
Then: diameter * thickness=minimum sectional area/3.14=500/3.14=160
Max (diameter/thickness)=38060/215=177
Max (diameter)=177* thickness
Min (diameter)=160/ thickness
Max (thickness)=diameter/2
Min (0.787* diameter2* thickness)=10000000
Min (diameter)=3565/sqrt (thickness) or min (thickness)=(3565/ diameter)2
It is obtained in conjunction with max (diameter):
Min (diameter)=3565/sqrt (thickness)=min (177* thickness)
Min (thickness)=8, corresponding unique (diameter)=1416
It is obtained in conjunction with max (thickness):
Min (thickness)=(3565/ diameter)2=diameter/2
Release 35652* 2=min (diameter)3
It obtaining min (diameter)=294, corresponding thickness is greater than 100, therefore is reset to 100, it obtains:
(3565/ diameter)2=100
3565/ diameter=10
3565/10=diameter
Corresponding to diameter at this time then becomes 357
Therefore teachings are as follows: diameter 357 to 1416, thickness 8 to 100
After thickness increases, corresponding minimax diameter can determine diameter range by max (diameter) and two min (diameter)
Value, vice versa.
Step 105, using thickness as benchmark variable quantity, thickness value pair in range is calculated according to the known quantity that previous step obtains
The practical minimum sectional area answered, optimization are completed.
This step is originated from range undetermined to termination, with fixed step size using step-by-step method can be used with a certain unknown quantity
It adds up and does calculating to range ends value undetermined.It is unknown dependent on some that this method is suitable for single unknown quantity or other unknown quantitys
Amount, and range is smaller.Also can be used prompt drop method or climbing hill algorithm, advantage be calculate it is very fast, the disadvantage is that for Non-monotonic function,
Optimal solution may be lost.
Because in engineering, plate thickness is integer, and caliber is then relatively flexible, therefore optimizes using plate thickness as basic variable, it may be assumed that plate
Thickness gradually increases and calculates for step-length with 1 from 8 to 100, this step is suitble to using zooming.Final gained size are as follows: 8/
1416mm。
It should be noted that above example is calculated only for an operating condition, and because being led to very much area greatly by curved
It is controlled by bending coefficient, will be increasingly complex in actual conditions, but optimization can be fully achieved using method provided by the invention
