The optimal design about the structure of oaring dynamometer device

The key parameters of oaring dynamometer device are optimally designed in order to improve the accuracy of measurements. Traditional optimization methods are difficult to used for reasons of the structure, material and the particularity of manufacturing process of the oaring. Additionally the mechanics characteristics will become complicated with the device installed. This paper established parameterized model for structure of the device and mathematic model for optimal calculation, by using ANSYS software, and optimally designed the pivotal geometry parameters of sleeve structure. Results show that the diameter of sleeve can be reduced 2.45mm compared to the predesign dimension. Experiments were performed to guarantee the reliability of the optimization results.
