Abstract: To accurately measure the transient impact force of a newly developed linear motor-driven punch, a computer-aided testing system was dynamically calibrated. The frequency characteristics of the entire testing system were calculated using the system identification method based on the results of the dynamic calibration. The calculation results show that the established mathematical model is effective, and the dynamic testing system can be used for load testing of prototypes and performance testing of finalized products during the development process. Keywords: Linear motor, Dynamic computer testing system Keywords: Linear motor, Dynamic computer detection system 1. Overview With the development of science and technology, dynamic testing systems are increasingly being applied in scientific research, technological development, and engineering practice. This requires a quantitative and in-depth understanding of the laws governing parameter changes in various transient processes, which urgently necessitates further development of dynamic testing technology.
