【Abstract】 The article researches into the problem of finite frame optimizing design of boom system of concrete pumping vehicle. To the boom system of concrete pumping vehicle, the intelligent algorithm of BP neural network is applied in the paper to design a nonlinear mapping relationship among stress, strain and structure variables. Subsequently, genetic algorithm is used to optimize the data and obtains a better result.更多还原
