摘　　要：时栅传感器在产品化过程中暴露出设计局限于传感器结构本身,而缺乏系统化的设计与优化方法;设计和实验过程分散,无法充分利用统计学知识建立模型;产品设计高度依赖于设计人员的经验等严重制约产品化进程的问题。以磁场式时栅为研究载体,采用均匀设计方法进行了试验设计,利用逐步回归分析对实验结果进行分析,构建了考虑多参数协同作用的传感器模型设计方法。开展了仿真试验和样机试验,结果表明:基于该方法建立的传感器模型具有良好的可预测性能,建立的精度模型与仿真数据拟合度达89%,置信度大于92%,能够有效地反映时栅传感器的精度,对于时栅传感器的设计和优化具有重要的借鉴意义。The productization process of time-grating displacement sensors has revealed that the design of these sensors is primarily focused on the sensor structure itself,lacking a systematic design and optimization method.The design and experimental process are fragmented,making it impossible to fully utilize statistical knowledge to establish a model.The product design heavily relies on the experience of designers,which has significantly constrained the productization process of the sensors.Addressing the afore mentioned issues,this paper uses the magnetic field time-grating displacement sensor as the research subject.The experimental design was conducted using the uniform design method,and the experimental results were analyzed using stepwise regression analysis to construct the sensor model design method.Simulation tests and prototype tests were performed,and the results indicate that the sensor model,built based on this method,exhibits good prediction performance.The established accuracy model fits the simulation data by 89%with a confidence level of over 92%.This can effectively respond to the accuracy of the time-grating sensor,which is of great significance for the optimal design of the time-grating displacement sensor.The productization process of time-grating displacement sensors has revealed that the design of these sensors is primarily focused on the sensor structure itself,lacking a systematic design and optimization method.The design and experimental process are fragmented,making it impossible to fully utilize statistical knowledge to establish a model.The product design heavily relies on the experience of designers,which has significantly constrained the productization process of the sensors.To address the aforementioned issues,this article uses the magnetic field time-grating displacement sensor as the research subject.The experimental design is implemented using the uniform design method,and the experimental results are analyzed using stepwise regression analysis to construct the sensor model design metho
