AI Technical Summary

Technical Problem

Existing fuel tank structures and molding processes are insufficient to meet the requirements of lightweight product design, and the processes are complex and difficult.

Method used

An integral fuel tank is designed using additive manufacturing technology, including a front frame, a rear frame, an upper skin, a lower skin, an oil intake chamber, an oil intake port, an oil delivery channel, a filling port, and an overload chamber. The pipelines are integrated with the tank wall through integral molding, eliminating the oil and gas pipelines inside the tank. Weight reduction grooves and ring ribs are designed to improve strength and reduce weight.

Benefits of technology

The internal structure of the fuel tank has been simplified, improving strength and reducing weight. The process is simple, the cycle is short, and the shape accuracy is high, achieving a lightweight design.
