The design of the main beam of the electric flatbed achieves the purpose of lightweight framework

In the design of electric flatbed products, the main beam of the frame is the design point. Dimensional optimization and shape optimization are detailed designs that the designer performs after a design change in the shape of the model. Size optimization is achieved by changing the characteristics of the structural elements to achieve stress or displacement, etc. Within a specific design range. Shape optimization is to change the mechanical properties of the model by changing certain shape parameters to achieve stress or displacement within a reasonable design range.

For the electric flatbed design, the double beam structure welding process is good, the tire layout is convenient, and the overall structure of the main beam does not require topology optimization. The size and shape of the main beam (which occupies most of the frame) is optimized. The main beam of the electric flatbed is made of I-beam. The stiffness of the I-beam can be improved by increasing the thickness of the web, the height of the web, the thickness of the wing and the width of the wing. High stress hazard areas can be improved by local reinforcement.

The size and shape are optimized to make the web of the main beam of the electric flatbed thinner and higher, reducing material consumption and achieving the goal of a lightweight frame. Therefore, within a reasonable range, increasing the thickness of the fins and the height of the web has a significant effect on increasing the rigidity of the frame, reducing stress concentration and weight reduction, and increasing the thickness of the web. The rigidity of the frame of the electric flatbed is not obvious.

Electric flatbed is a kind of railway transport car, mainly used for mobile forklift, etc. Used in brick factory, kiln factory, refractory factory, ceramic factory, roasting factory, electric kiln car, electric kiln car, etc. Engineering, tunnel sanitation, electric dump trucks, and electric sanitation trucks are electric transport vehicles that, because of their convenience, robustness, economy, utility, and ease of cleaning, become heavy transport vehicles.
