Abstract
Aim To develop the truss topology optimizing program by refering to the biology hypothesis of Lamarck. Methods The stability of the pressure bar was considered when optimizing the truss topology and the bar's cross section area. The constraints included the allowable stress of the material and the allowable stress of the pressure bar's stability. As the optimal result, the bars whose cross section areas are smaller than the threshold were removed, and each bar was made to bear the load as possible as the materials allow. Results The results of two optimization examples showed that the weights of the structure were reduced and the stability requirement was satisfied by this method. Conclusion This method is practical and reliable. It is an efficient optimization method. It can be used for the design of the complex truss structure.
