The illustratively a kind of commercial-vehicle cab vehicle dynamic provided by the utility model that remarks additionally below is drenched with rain and mud
Powder-refining with water splashes the design principle of simulation system
Driving force is provided using the air pressure that vehicle-mounted gas source generates for spray；Calculating that design is a according to test water amount can be with
The firm water tank 101 with vehicle is used as rainwater source；It designs a set of spray equipment and executes water droplet sprinkling, to simulate work of dynamically drenching with rain
Condition；A set of water yield adjustable control means are designed, water yield adjusting simulates different rainfall；Design installation is a set of in wheel storehouse
Spray equipment with realize muddy water splash simulation；In test process, be added aqueous pigment in water tank 101, Simulated rainwater and
Muddy water is splashed to the trace on vehicle body.To sum up, the utility model major design and theoretical calculation analysis relate generally to following several
Aspect: 1) water tank apparatus structure；2) power source；3) water controls；4) rainwater sprays；5) wheel storehouse spray；6) pigment characteristics is set
It is fixed etc..
Specifications clear first, the utility model need to realize the simulation of heavy rain, moderate rain, light rain；According to reality
Project it needs to be determined that experimental test minimum duration Tmin；Determine that nozzle water outlet should be uniformly and in 60 ° of cone shapes, spray
The bore dia of mouthModel is unified, the size of all nozzles (nozzle of rainwater spray nozzle and the nozzle of wheel storehouse spray nozzle) and
Internal structure is answered identical.
The design of water storage device structure: it since water tank 101 needs to bear the pressure of vehicle-mounted gas source, needs to water tank 101
Inside carries out reinforcement processing, and the inner wall of water tank 101 designs the reinforcing rib for having interval to be evenly arranged, and improves the whole of water tank 101
Body structural strength, meanwhile, it avoids stress from concentrating to be allowed to uniform force, water tank 101 is designed as cylindrical body.Devise rigidity
Intensity is all satisfied the water storage tank bracket 102 of requirement being made of two U-shaped boards and connecting rib, passes through two U of water tank 102

Degree；D is round tube inside diameter；V is the flow rate of liquid in pipeline, utilizes the relative theory of round tube turbulent flow in hydrodynamics:
(Q is total spray flow, and d is round tube inside diameter)；G is acceleration of gravity.
hm: the local losses in pipeline, can engineering experience estimated by the 15% of linear loss: hm=0.15 × hf。
Δ z: for the difference in height of water tank 101 and nozzle；
ρ: fluid density；
It is the pressure difference Δ P that can determine atmospheric pressure value and 201 water outlet atmospheric pressure value of main line in water tank 101 by above formula
Value；
And then the final value for determining the application pressure P in water tank 101 is calculated by following formula:
P=Δ P+P0
It brings total spray flow Q1, Q2, Q3 of light rain, moderate rain and heavy rain into above-mentioned formula respectively to calculate, can obtain
The application pressure of simulation light rain, moderate rain and heavy rain must be controlled are as follows: P1, P2 and P3.
