Design of a New Air Winch Performance Test Platform and Analysis on its Bracket

Due to the complex working environment and relatively backward manufacturing technology, an important industrial tool, the air winch, faces lots of problems such as wire rope breaking and brake instability. This paper presents a new mechanical loading tower type air winch performance test platform designed to test air winch after it is manufactured. In order to ensure security during the test, this paper proceeded with numerical analysis for the bracket. Results of the analysis showed: the maximum stress of the bracket when loaded was 10 t at 156MPa which was far below its yield stress, and its maximum displacement was 0.527 mm, which would not produce large deformation. The natural frequencies of the bracket’s free mode are smooth sequential which do not exist in local breakpoint, and the interval of each frequency is large, thus it can avoid the close mode. Because the first mode frequency is 37.255 Hz, so the bracket can avoid resonance caused by the vibration of the system due to the instability of the gas source during the test. This paper also analyzed the stress of the bracket during the test to help the operator predict the danger point and prevent the occurrence of overload. In addition to introducing a new mechanical loading tower type air winch performance test platform, the authors also present a detailed analysis of the bracket. The new test platform can effectively compensate for the lack of air winch performance testing in domestic
