Abstract
The concept of assembly mechanics was applied to improve the traditional horizontal assembly technology of low pressure turbine unit of commercial high bypass ratio aero-engine. An advanced horizontal assembly technology was developed based on deformation control by mechanical simulation analysis of the horizontal docking process of low pressure turbine unit. The result demonstrated that this technology realized the installation of low pressure turbine unit with high precision, high efficiency and high reliability. In addition, compared with traditional experience assembly, the guided tool structure was more concise by contributing to around 70% reduction of the weight, and the docking difficulty was greatly reduced by contributing to more than 60% increase of the assembly efficiency and 100% increase of the success rate of one-time docking.
