Abstract

Four-axis strain gauges, widely employed in military control systems, often experience increased tolerance and potential malfunctions when subjected to harsh temperature and vibration conditions. In response to this challenge, this paper presents a compensation method designed to mitigate the tolerance associated with four-axis strain gauges used in military applications. Firstly, we conduct an evaluation and analysis of the tolerance linked to strain gauges, considering factors such as ambient temperature variations and signal processing circuitry. Subsequently, we introduce a software-based approach that incorporates temperature sensors to counteract the effects of ambient temperature, thereby enhancing performance in both tolerance and offset correction regions of the strain gauges. Experimental results, obtained through the application of this software technique, demonstrate reliable operation during temperature and operational tests.
