The cost that people is vibrated in storehouse surface, including vibrate, the sum of Expenses Cost of doing over again.Mechanical passability and machinery in constraints is empty
Intersexuality judgement is described in detail in step 4.
4. establish storehouse surface vibrate task distribution simulation model.
In the simulation model, it is contemplated that the complexity of real system is bound the research range of analogue system, and
And in the case where ensuring that not influencing analogue system reflects the authenticity of objective reality, simulation model is simplified, is done as follows
It is assumed that：
1) assume not considering the limitation that working sources are supplied in storehouse surface concrete vibrating, that is, put aside concrete production system
The influence of system and Lan Jideng vertical-horizontals transportation system；
2) many factors such as time parameter, dam body parameter and other construction parameters etc. for influencing concreting are all reduced to
Deterministic parameter inputs, and puts aside their randomness.
As shown in figure 5, in the simulation model, using event unit propulsion mode, when storehouse surface is vibrated task undertaker hair
Raw change manually vibrates state and when the machinery state of vibrating switches, simulation clock advance mechanism is utilized to refresh scene.
In the simulation model, mechanical passability refers to that machinery is sentenced what can the storehouse surface by state constraint pass through
It is disconnected.It is to complete the premise of task of vibrating that vibrating vehicle can pass through in storehouse surface.Mechanical passability and storehouse surface state and machinery itself
Technical parameter it is related.For some pours storehouse, storehouse surface state is known.Pouring storehouse can be with a polygon m come table
Show, expression pours bin location vector, and it is also available more to pour the structural elements such as reinforcing bar, template, functional component, the built-in fitting on storehouse
Side shape ni(i=1,2 ..., i ..., j ..., s) it indicates.
Location={ L1,L2,...,Li,...,Lj,...,LsIndicate the position vector of these structural elements.Such as Fig. 6
Shown, black pattern fill part indicates to pour the structure reinforcing bars of storehouse upstream and downstream face laying,Indicate structural elements to pouring storehouse
The shortest distance on side,Indicate the shortest distance between two structural elements.With reference to the technical parameter of vibrating vehicle, W is usedvIt indicates
The passability judgment rule of the maximum width of vibrating vehicle, lift surface vibrating vehicle is as follows：
1) whenWhen, vibrating vehicle is in structural elements niAnd njBetween can pass through；
2) whenWhen, vibrating vehicle is in structural elements njAnd nj+1Between can pass through；
3) whenWhen, vibrating vehicle is in structural elements niIt can pass through between the side of storehouse with pouring；
4) whenWhen, vibrating vehicle is in structural elements niAnd njBetween can not pass through；
5) whenWhen, vibrating vehicle is in structural elements njAnd nj+1Between can not pass through；
6) whenWhen, vibrating vehicle is in structural elements niIt can not pass through between the side of storehouse with pouring.
In the simulation model, it is mistake that the vibrating spear of vibrating vehicle acts on the concrete of a certain construction area that machinery, which vibrates,
Journey, this requires vibrating spear reachable in space.Spatial accessibility is used to judge that can the vibrating spear under the traction of vibrating vehicle mechanical arm to arrive
Up to construction area and smoothly complete the task of vibrating of construction area.The influence factor master of vibrating vehicle spatial accessibility in storehouse surface of constructing
To include vibrating vehicle working space and construction storehouse surface state.The maximum operation space of the vibrating vehicle of a certain model is according to turner of vibrating
Make design size between each hinge of device and slewing area it was determined that vibrating vehicle on a concrete dam block lift surface
Reachable tree can be by being calculated based on the kinematical analysis and simulation of D-H methods.Therefore, vibrating vehicle reachable tree can be used as
Know condition.On this basis, influence of the construction storehouse surface state to mechanical space accessibility include mainly：1) essential attribute of storehouse surface
State, such as elevation, residing monolith, shape and size；2) the laying state of storehouse surface structural elements, as structural elements quantity,
In the location of storehouse surface, shape, size, construction process requirement etc..
Spatial accessibility of the vibrating vehicle in storehouse surface can be used following (0,1) distribution function to indicate：
In formula (2), x is certain point in storehouse surface, UmFor the reachable tree of vibrating vehicle in certain storehouse surface.
The spatial accessibility judgment rule of lift surface vibrating vehicle is as follows：
1) when vibrating vehicle is in its storehouse surface reachable tree domain, it is believed that vibrating vehicle space is reachable；
2) when vibrating vehicle is not in its storehouse surface reachable tree domain, it is believed that vibrating vehicle space is unreachable.
In the simulation model, as shown in Figure 7, it is assumed that band sequence of construction is the best sequence of construction of mechanical storehouse surface of vibrating,
Machinery can band application property be that the judgement of task of vibrating can be completed according to band sequence in storehouse surface to vibrating vehicle, can band apply
Vibrating vehicle need not frequently be carried by crane in work, that is, process of vibrating.It can judge mechanical energy by the steering situation of vibrating vehicle
No belt construction, minimum turning radius can be used as machinery can band construction a judge index.Vibrating vehicle is crawler type
Traveling vehicle, as performance parameter, vibrating vehicle minimum turning radius is by two track gages and crawler belt deflecting roller maximum deflection angle etc.
It determines.With reference to the calculating point of automobile, the minimum turning radius computational methods of caterpillar and boom-type roadheader turning radius
Analysis, vibrating vehicle crawler belt turning radius are
In formula (3), RwbFor vibrating vehicle crawler belt turning radius, m；WbFor two track gages, m；αmaxIt is maximum for crawler belt deflecting roller
Deflection angle, (°).When vibrating vehicle is pure creeper truck, Rwb=0.
Geometrical relationship between vibrating vehicle appearance and size, the cantilevered swing that vibrates, crawler belt steering etc. is as shown in Figure 8.O is to vibrate
