Structural Design of Packaging

1.Iron Frame Desig

• Material Selection:The iron frame is typically made from high-strength steel,such as Q235 or Q345,which offers excellent mechanical properties to withstand significant loads.

• Customized Dimensions:The dimensions of the iron frame are customized based on the shape and weight of the power generation unit.The frame consists of several vertical and horizontal bars welded together to form a robust grid structure that enhances overall stability.

• Connection Method:The various components of the frame are connected by welding to ensure a strong bond.The weld points must undergo rigorous quality inspection to guarantee their strength and reliability.

2.Wooden Crate Design

• Crate Board Material:The boards of the wooden crate are usually made from plywood or solid wood panels with good compression and impact resistance.The thickness of plywood typically ranges from 15mm to 25mm,while the thickness of solid wood panels is determined based on specific requirements.

• Connection Method:The connection between the crate boards and the iron frame is crucial and can be achieved through nailing or screwing to ensure a secure bond.When nailing,the spacing between nails should be reasonable to ensure a tight fit between the crate boards and the frame.

• Lifting Point Design:Lifting points should be reasonably arranged on the top and sides of the wooden crate for easy handling by lifting equipment.Lifting points are usually made of steel rings or ears welded to the frame of the crate to ensure their strength and reliability.

3.Internal Cushioning Design

• Cushioning Material Selection:Inside the wooden crate,cushioning materials such as foam plastic or rubber pads should be reasonably filled according to the shape and weight of the power generation unit.These cushioning materials should have good elasticity to absorb and disperse external forces and protect the power generation unit from damage.

• Cushioning Structure Design:The thickness and distribution of cushioning materials should be optimized based on the shape and weight of the power generation unit.Sufficient cushioning materials should be placed at the bottom,sides,and top of the power generation unit to effectively absorb vibrations and impacts during transportation.

• Fixing Method:Cushioning materials should be fixed inside the crate with glue or straps to prevent them from shifting during transportation,which could affect the cushioning effect.

Transportation Standards

1.Road Transportation

• Stability Requirements:During road transportation,the wooden crate must withstand the inertial forces generated by frequent vehicle starts,stops,and turns.Therefore,the reinforcement structure of the crate,such as steel straps and angle irons,must be able to resist these horizontal forces.

• Ease of Loading and Unloading:The bottom of the crate should be designed with a structure that facilitates forklift handling,such as appropriately sized forklift slots.The dimensions of the forklift slots should comply with the specifications of the forklift to ensure smooth insertion and handling of the crate.

• Protective Measures:During transportation,the crate should be covered with a waterproof tarp or plastic film to prevent rainwater and dust from entering the crate and damaging the power generation unit.

2.Railway Transportation

• Vibration Resistance:During railway transportation,the vibrations from train travel are relatively large,and the cushioning structure inside the crate must be effective in dealing with them.The thickness and distribution of cushioning materials should be optimized based on the vibration characteristics of railway transportation.

• Compression Strength:The compression strength and stacking strength of the crate are also very important to prevent damage from stacking during train travel.The stacking height of the crate should be designed based on its compression strength to ensure that it does not deform or get damaged during stacking.

• Securing Measures:During railway transportation,the crate must be securely fastened to the carriage with steel straps or chains to prevent it from sliding or tipping over during transportation.

3.Marine Transportation

• Moisture and Corrosion Resistance:Marine transportation requires consideration of moisture resistance,corrosion prevention,and wave resistance.The exterior of the crate can be coated with waterproof paint or wrapped with moisture-proof packaging materials,and desiccants can be placed inside to prevent moisture damage to the equipment.The cushioning materials should also have certain water-resistant properties to prevent seawater from seeping into the crate.

• Compression Strength:During marine transportation,the compression strength and stacking strength of the crate must meet the requirements of maritime transport.The stacking height of the crate should be designed based on its compression strength to ensure that it does not deform or get damaged during stacking.

• Securing Measures:During marine transportation,the crate must be securely fastened to the cargo hold with steel straps or chains to prevent it from sliding or tipping over during transportation.

Compression Strength Testing Standards

1.Material Strength Standards

• Wood Strength:The bending strength of wood should exceed 11MPa,the compression strength should be no less than 7MPa,and the tensile strength should reach 14MPa.These strength indicators are key to ensuring that the crate can withstand various external forces during transportation.

• Steel Strength:The strength of the steel used in the iron frame should comply with relevant standards,such as Q235 or Q345,with yield strength and tensile strength meeting design requirements.

2.Testing Methods

• Static Load Testing:Place the crate on a testing machine and gradually apply pressure until the crate reaches its ultimate load-bearing capacity.Record the deformation of the crate under different pressures to assess its compression performance.

• Vibration Testing:Simulate the vibration environment during transportation to test the crate's compression performance under vibration conditions.Vibration testing is usually conducted on a vibration table,with vibration frequency and amplitude set according to relevant standards,and observe the damage to the crate during vibration.

• Stacking Testing:Simulate the stacking conditions of the crate during transportation to test its stacking strength.Stack multiple crates together and apply a certain pressure,and observe the deformation and damage of the crate during stacking.

3.Design Verification

• Finite Element Analysis:In the design stage,finite element analysis can be used to verify the strength of the crate structure.Through finite element analysis,the stress conditions of the crate under various working conditions can be predicted,potential weak points can be identified in advance,and the design can be optimized.

• Experimental Verification:In actual production,rigorous experimental verification should be carried out to ensure that the compression strength and stacking strength of the crate meet design requirements.The results of the experiments should be recorded for use as an important basis for quality control of the product.

Advantages of Packaging

1.Robust Structure

• Iron Frame Support:The iron frame of the crate provides a strong support structure that can withstand significant loads,ensuring that the power generation unit is not damaged by external forces during transportation.

• Wooden Crate Protection:The boards of the wooden crate have good compression and impact resistance,offering additional protection to the power generation unit and preventing damage from collisions and compression during transportation.

2.Adaptability

• Multiple Transportation Modes:The iron frame wooden crate is suitable for various transportation modes,including road,rail,and sea.Its design can be optimized based on different transportation requirements to ensure reliable protection under various transportation conditions.

• Environmental Adaptability:The moisture-proof and corrosion-resistant design of the crate enables it to adapt to different environmental conditions,whether in hot and humid tropical areas or cold polar regions,effectively protecting the power generation unit.
