摘要：

The integrated precision casting technology of aluminum alloy is one of the important ways to achieve lightweight of automobiles. Firstly，lightweight aluminum alloy material，investment vacuum suction casting process，and topology optimization are adopted to carry out an integrated design of material，process and structure" for the front subframe and dashboard crossbeam of the white body in this paper. Secondly，the weight，research and development cost，and development cycle of integrated aluminum alloy structural components are compared to the original steel components，which are significantly reduced. Finally，finite element simulation analysis and bench tests are conducted on the stiffness and modal of the white body with integrated precision cast aluminum parts. The results show that after the integrated design，the front subframe and dashboard crossbeam has reduced weight by 36.6% and 30.8% respectively，while the performance of the white body meets the design requirements. © 2024 SAE-China.
