Research on Mechanical Manufacturing with Posture Optimization of Installation of the Bolts in Large Component Assembly

摘要

To improve the assembly efficiency, an optimization model is proposed to achieve the optimal posture of the component of the bolts installation. The component is measured and aligned by an automatic system, which consists of some NC locators and coordinate measuring device. Based on the measurement data of the bolt hole and the end surface, the maximum diameter of the bolt that can pass through the joint hole is obtained by using morphology theory. The particle swarm optimization method is adopted to solve this problem, and the stability and efficiency of the calculated results are improved by controlling the initial distribution of particles. The numerical simulation experiment shows that the proposed method would be helpful to guide the alignment and docking of large components.
