Sensitivity analysis of truck structure based on CA algorithm

With the continuous improvement of modern CAE technology, structural reanalysis algorithm has gradually come into people’s vision and developed rapidly. The structure introduced in this paper is an accelerated calculation method. core idea to avoid complete analytical calculations after modification, reduce scale, save time, improve efficiency simulation effectively on premise meeting requirements accuracy. objective that based initial third-order modal information truck control overall quality structure. And it important guiding significance for practical production. In paper, different design variables are set combination with algorithm. While parameters modified, sensitivity analysis Taylor expansion theorem used verify feasibility accuracy method optimal
