| Abstract: | The mathematical models for automobile crane arms optimal design are established with the self weight as destination function under the condition of taking the arm's sizes as design varibles,taking the displacements of the top,the local and entire stabilities,and the initial areas as constrains.The optimal calculations are carried out to the QY12A employing the complex algorithm,the results show that the self weight is decreased greatly and the strength is utilized efficiently. |
