摘要
Abstract
The propulsion shafting systems of ships bear complicated loads and stresses in the sailing. A good load distribution is of great importance for ship's long-term and safe voyage. In this paper, a wireless telemetry system based on strain gages is designed to measure the dynamic loads of the propulsion shafting system in different shaft alignment states. Based on the strain data measured in different sections, a single-support load computation model is established. The real loads of different bearings are calculated. Experiment is carried out for the scaling model. The difference of results in the experiment and the finite element modeling is found to be small. Thus, reliability of this testing method is verified.关键词
