The load distribution of structure；Then the number N of air cushion suspension structure 3 and the driving power P of motor 5 are selected；
Concrete mode is that the number of air cushion suspension structure 3 is determined according to formula two:
Wherein: the bearing capacity of F2/N- air cushion suspension structure；
P0/ Pa- supply gas pressure；
Se/m2The effective area of air cushion.
Step 2:
Reasonable air cushion arrangement is selected according to the number N of air cushion suspension support construction and is determined with orifice outflow equation three
Air cushion air demand Q:
Wherein: cdThe discharge coefficient of nozzle, cvThe velocity coeffficient of eluting gas, A (m2The area of)-venthole, PS(Pa)-supply
Atmospheric pressure, R (J/molk)-gas constant, T0(K)-gas supply gas absolute temperature；
The arrangement of air cushion suspension structure determines the design of support stand 2, and air cushion suspension structure air cushion can be triangle
Arrangement, quadrangle arrangement, etc. row etc. column arrangement.It include air cushion 32 in air cushion suspension structure 3, air cushion support plate 31 supplies aperture
33, air cushion support plate 31 is connect with 32 adhesion of air cushion, while air cushion support plate 31 is fixedly connected with support construction 2, air cushion support
Plate 31, air cushion 32 are all communicated with gas supply aperture 33, after compressed gas enters air cushion by gas supply aperture 33, with gas air demand
Increase air cushion gradually expand, with corresponding control valve group formed air cushion suspension structure have bearing capacity.
Step 3: air cushion suspension hold-down devices 4 make driving wheel contact to earth, and determine 5 function of motor according to the adhesive force of driving wheel 6
Rate makes heavy load equipment realize revolution using friction-driven；Air cushion suspension hold-down devices 5 are fixedly connected with support device 2, group
At identical as air cushion suspension structure 3, selecting reasonable supply gas pressure that air cushion suspension hold-down devices is made to generate downward pressure makes to drive
Driving wheel 6 contacts to earth, and driving wheel 6 is connect with motor 5 by retarder, shaft coupling etc., because air cushion suspension structure 3 carries part load
Lotus reduces the power density that motor 5 drives driving wheel, makes heavy load equipment in air cushion suspension structure and motor drive mode group
Lower realize is closed to turn round.
Detailed description of the invention:
Fig. 1 is the schematic diagram that heavy load equipment driving is placed；
Fig. 2 is the structural schematic diagram of the combined drive method of heavy load equipment；
In figure: 1, heavy load is equipped, 2, support stand, 3, air cushion suspension structure: 31, air cushion support plate, 32, air cushion, 33, gas supply
Aperture, 4, air cushion suspension hold-down devices, 5, motor, 6, driving wheel.
Specific embodiment:
Step 1:
Formula one: W=f (F1, F2) (1)
The driving load proportion of heavy load equipment is distributed, the number N of air cushion suspension structure 3 and the driving power P of motor 5 are selected；
Wherein, f=aF1+bF2 and a+b=1；A.F1 (N) is the load distribution of motor driven systems；B.F2 (N) is air cushion suspension
The load distribution of structure；Then the number N of air cushion suspension structure 3 and the driving power P of motor 5 are selected；
Concrete mode is that the number of air cushion suspension structure 3 is determined according to formula two:
Wherein, the bearing capacity of F2/N- air cushion suspension structure；
P0/ Pa- supply gas pressure；
Se/m2The effective area of air cushion；
Before not driving, heavy load equipment 1 carries gravity by support stand 2.
Step 2: reasonable air cushion arrangement is selected according to the number N of air cushion suspension support construction and is gone out with aperture
