With the enhancement of environmental protection awareness and the limitation of resource consumption, the structural topology optimization and lightweight design of magnesium forgings in construction machinery have become the focus of current research. By optimizing design and material selection, the weight of parts can be reduced and lightweight can be achieved, which has the following aspects of research content.
First, the structure topology is optimized. Structural topology optimization is to minimize the use of materials by redistributing materials under given constraints, while ensuring the required stiffness and strength of parts. By using the optimization algorithm, the structure of magnesium forgings of construction machinery can be analyzed and optimized, and the best material distribution and shape can be determined. This optimization method can not only achieve lightweight parts, but also improve the utility rate of materials and reduce energy consumption.
Secondly, choose the appropriate materials. As a kind of material with light weight, high strength and good machinability, magnesium alloy has been gradually applied in the field of construction machinery. According to the use environment and requirements of construction machinery, select appropriate magnesium alloy materials, such as AZ31, AZ61, etc., under the premise of meeting the strength and stiffness requirements, reduce the material density as much as possible to achieve lightweight design.
In addition, the mechanical load borne by construction machinery parts during use should also be taken into account. By analyzing the working conditions and stress conditions of construction machinery, the structural form and material distribution of components are reasonably determined to ensure that they have sufficient stiffness and strength in the working process. Finite element analysis and other methods can be used to carry out load simulation and optimization design to find the best structure scheme.
In addition, new manufacturing technologies and processes can be explored. By using advanced manufacturing technologies, such as 3D printing and die casting, more refined and complex structural forms can be achieved, reducing the weight of parts, reducing material waste, and improving the performance and reliability of construction machinery.
All in all, structural topology optimization and lightweight design of magnesium forgings of construction machinery are important means to achieve lightweight and resource utilization efficiency of construction machinery. By adopting structural topology optimization methods, selecting appropriate materials, considering mechanical loads and exploring new manufacturing technologies, it is possible to optimize the design of construction machinery parts, reduce the use of materials, and improve the performance and sustainable development level of parts. This will have a positive impact on promoting the green development and environmental protection of the construction machinery industry.
