The specifications of the custom FRP heavy truck wind deflector will vary according to the specific model and customer needs. Typically, a custom cowl needs to consider factors such as wind resistance, aerodynamic design, installation suitability, and aesthetics.
Step 1: Material
Material: High strength glass fiber reinforced plastic (FRP) material, with good corrosion resistance, weather resistance, high temperature resistance, suitable for various climatic conditions.
Surface coating: UV resistant, scratch resistant, high gloss surface coating is available on demand to ensure the appearance of the hood is as good as new.
Step 2: Size
Customized dimensions need to be determined based on the vehicle’s body structure, aerodynamic requirements and installation space. Common parameter ranges include:
Length: Usually within the range of 1000mm-2500mm, adjusted according to the requirements of the front and wind resistance.
Width: Depending on the body width of the truck, lane adaptability and aerodynamic effects, the custom width is between 800mm and 1500mm.
Height: Generally set at 250mm-600mm, according to the functional requirements of the guide hood to adjust, the higher guide hood can more effectively optimize the air flow, reduce wind resistance.
The detailed dimensions and design requirements of the vehicle should be provided with the manufacturer during customization.
Step 3: Weight
Weight range: 10kg-40kg (depending on the size, thickness and design of the hood). The design is usually kept as light as possible to reduce the impact on the truck load.
4. Aerodynamic performance
Wind resistance coefficient (Cd value) : With precise calculation and design, a custom hood can reduce the wind resistance coefficient (Cd value) by approximately 10% to 20%, helping to improve fuel efficiency and reduce the wind impact of the vehicle.
Fuel saving: Depending on the specific model and driving conditions, a reasonably designed wind deflector can achieve fuel saving of 3%-10%.
5. Installation mode and adaptation
The installation methods of custom wind deflector usually include:
Overhead mounting: Suitable for designs that optimize air flow through the top.
Side mount: Suitable for side drag control, can be fixed through the side of the body, common in most heavy trucks.
Suspension mounting or mounting: It can be hung on the roof or rear of the car through the mounting design, suitable for models with special wind resistance requirements.
Installation adaptation: When customized, it is necessary to accurately design according to the shape of the car body and the installation point to ensure that the guide hood can perfectly match the structure of the truck to avoid affecting the driving safety after installation.
6. Temperature and weather resistance
Temperature range: usually -40℃ to +80℃, can cope with high temperature or cold environment, to ensure the stability of the hood in various climatic conditions.
Uv resistance: The design will take into account the impact of ultraviolet radiation on the material, and the surface of the glass fiber reinforced plastic material is usually added to the anti-ultraviolet coating to extend the service life.
7. Functional design
The functional design of the custom fairing includes:
Improve Fuel efficiency: Improve truck fuel economy by optimizing air flow lines and reducing vehicle drag.
Stability improvement: reduce the wind resistance in windy weather and increase the stability of the vehicle at high speed.
Noise control: Reduce wind noise at high speeds through aerodynamic optimization.
Appearance aesthetics: The color, shape and appearance design can be customized according to customer requirements, so that the guide hood and the body design are coordinated.
Ready.
