Parameter Selection Method for Accuracy Optimization of Time-Grating Displacement Sensor Based on Orthogonal Experimental Design

Time-grating displacement sensors have been widely used in various application fields such as machineries., automobiles., aerospace., and defense with their merits of high accuracy., reliability., and low cost. However., the problem of over-reliance on experience during the product parameter design process without scientific advisory was exposed during the time-grating sensor manufacturing process. In addition., it brought about the problems of production efficiency decline due to delayed design and experimental processes. This paper discusses the influence of different stages on the optimum parameters of a Time-grating displacement sensor. By using the orthogonal experiments and the intuitive analysis of the experiment findings., this paper aims to provide reliable and effective strategies for the component design of a Time-grating displacement sensor. The influence of different parameters on the sensor's accuracy was studied by establishing a sensor model and using finite element simulation software experiments. The experimental results show that other parameters correlate with accuracy., among which pole number and excitation signal significantly impact sensor accuracy. The research work carried out in this paper can provide a basis for various parameter designs in the production process and has a certain reference value for the optimal design of time-grating sensors.
