Abstract Material handling operations give rise to Euler and Coriolis forces whose impacts should be minimized already at the stage of selection of the system parameters and mechanism structure. Effective optimization, confirmed by dynamic analysis, allows the dynamic overload values to be significantly reduced at the stage of design of the steel structure, resulting in a lighter and cheaper structure. Basing on the mathematical model the optimization criteria were formulated in the form of quadratic functionals for each crane mechanism. Solving the functionals to find the minimum values yields a set of optimal parameters of mechanisms such that their interactions should be optimal. The innovative feature of the presented solution is a comprehensive approach to optimization of multi-drive systems, targeting the vibration reduction of the load suspended on the hook and minimizing forces acting in the ropes. Optimization tasks should be executed independently, in the specified order resulting from feedback interactions between respective mechanisms. This approach paired with the method of selective analysis of mechanisms structures will be further developed into the method of synthesizing globally optimal configurations of interacting mechanisms.

优化起重机机构以减少振动

摘要 物料搬运操作会产生欧拉力和科里奥利力，在系统参数和机构结构选择阶段就应将其影响降至最低。经动力分析证实的有效优化可以在钢结构设计阶段显着降低动力过载值，从而使结构更轻、更便宜。基于数学模型，优化标准以二次函数的形式为每个起重机机构制定。求解泛函以找到最小值会产生一组最佳机制参数，以便它们的相互作用应该是最佳的。所提出的解决方案的创新特征是优化多驱动系统的综合方法，旨在减少悬挂在吊钩上的负载的振动，并最大限度地减少作用在绳索上的力。优化任务应该独立执行，按照各个机制之间的反馈交互产生的指定顺序。这种方法与机制结构的选择性分析方法相结合，将进一步发展为综合相互作用机制的全局最优配置的方法。
