Optimization Of The Box Section Of The Main Girder Of The Bridge Crane According To The Criteria Of Lateral And Local Stability Of Plates

The paper considers the problem of optimization of the box section of the main girder of the bridge crane. Reduction of the girder mass is set as the objective function. The method of Lagrange multipliers was used as the methodology for approximate determination of optimum dependences of geometrical parameters of the box section. The criteria of lateral stability and local stability of plates were applied as the constraint functions. The obtained results of optimization of geometrical parameters were verified on numerical.
