| ABSTRACT |
|
With the development of the economy, the demand for heavy-duty transportation vehicles is increasing. Due to
the limitations of national standards and regulations, and the market’s requirements for the reliability and economy of the
whole vehicle, it is urgent to optimize the structure of each part of the heavy-duty transportation vehicle. In this paper, the
sub-frame of a certain type of cement mixer truck is taken as an example. Firstly, the finite element analysis method is used to
find the structural defects of the existing products through static analysis and modal analysis of the existing products under
full-load condition. Then, the density method is used to carry out topology optimization design of the existing sub-frame
structure, and the optimized frame is checked. The conclusion is expected to provide a theoretical basis for the lightweight
design of heavy transport vehicles. |
