Commercial vehicle power steering oil tank support performance improvement optimization design method, terminal and support

The invention provides a commercial vehicle power steering oil tank support performance improvement optimization design method, a terminal and a support, and belongs to the technical field of commercial vehicles. S101, the modal boundary condition, the frequency response boundary condition and the fatigue analysis boundary condition of the commercial vehicle power steering oil tank support are defined and designed; s102, a force transmission path is extracted, and static stiffness topological optimization parameters are set; the static stiffness topological optimization parameters comprise a design variable D, a response R, a constraint C and a target O; and S103, the structure of the steering oil tank support is determined. The static stiffness entity topology of the power steering oil tank support is optimized, so that the size of the support is superior to that of a benchmark piece in modal, frequency response force, fatigue and other stress performance. And moreover, the bracket with lower weight is adopt
