R & D ADVANTAGES

    In the 21st century, human beings put forward new requirements for metal structural materials: the research and development of new materials should not only be able to adapt to the development of high technology and meet the needs of human beings' high-quality life, but also require rich resources, high efficiency, low energy consumption and easy recovery, which is conducive to sustainable development; it must be able to meet the increasingly stringent requirements of environmental protection laws and regulations in the future to enter the market and application smoothly.

    China is a big country of magnesium resources. We should take advantage of this condition, improve the value of magnesium resources, adjust the industrial structure, expand the application of magnesium and lead the development of magnesium industry...

    In design and development, we must complete：
    The die-casting magnesium alloy parts are developed to replace other materials; FEA tools are used to verify whether the designed product performance meets or exceeds the customer's functional requirements; Complete the final product structure design that meets the requirements of product performance and die casting and other production processes;
    In general: the development process includes：
    1、Complete conceptual design according to customer requirements；
    2、Set load case according to customer's functional requirements and complete FEA analysis；
    3、According to the customer's functional requirements, set load case, complete FEA analysis, complete the final design of product structure according to FEA results and die casting process requirements.
    FEA analysis project list:
      LOAD Case Target
    1 1.1 Column Stiffness(V)
    1.2 Column Stiffness(L)    		 500 N/mm
    750 N/mm
    2 PSAB Loading 2kN *2
    (up and down)    		 Stress <= 130MPa
    (YS)
    3 Knee Loads(4kN*4) No failure
    4 Side Impact Loading Peak load > 15kN
    5 ODB Loading Peak load > 8kN
    6 NVH >38Hz?
    85% of column?
      Weight <5kg
    Note: all functional requirements come from customers, and the target requirements will vary with different customers.
    NVH analysis:

    *Note: NVH value requirements may be absolute size or ratio to chassis NVH value.

    Side impact strength analysis:
    The development cycle is based on appropriate customer schedule requirements.
    The ideal design cycle includes:
    1、Complete the conceptual design according to the customer's requirements;----〉2 weeks
    2、Set load case and complete FEA analysis according to customer's functional requirements; ----〉9 weeks
    3、According to the result of FEA, finish the final design of product structure; ---〉4 weeks
    So: the total development cycle is: 14 – 16 weeks
