Nonlinear Analysis and Optimization on Intricate Slender Boom Structure of Crawler Crane in Safety Hoisting Wind Turbines

Wind power clean energy has become a hot spot in human activities. In response to the problems of security risks and low efficiency in the process of wind turbine hoisting, a new nonlinear analysis and optimization method of the complex slender arm structure of the crawler crane is proposed. By using the coupling optimization method of engineering discrete variable iteration and collaborative structural nonlinear mechanical property analysis, the optimal engineering plan satisfying the design constraints can be directly obtained under the condition of accurately capturing the structural mechanical properties under complex loads step by step. The multimodule combination program operation combining the enhanced direct search method with the multiparameter modeling analysis of the boom significantly improves the efficiency of structural optimization and ensures that the optimization solution meets the engineering requirements under complex constraints. The material consumption of the optimized boom is reduced by 26.7%, which improves the standing stability of the crane during wind power installation, and the research effect is remarkable. This study provides an effective optimization method for the structure design of crawler cranes for large-scale wind power equipment, which improves the safety and efficiency of operation. It also provides a new method framework for the optimization design of construction machinery in the future, which can provide a reference for the comprehensive optimization of nonlinear large deformation complex engineering structures affected by multiple factors.
