In the current firearms dynamics research, the majority of studies focus on the extraction resistance and subsequent recoil forces, with relatively fewer studies on the unlocking force. This study focuses on the measurement of firearm unlocking force by analyzing the previously designed measurement device. By employing theoretical and dynamic simulation analyses, the variations of unlocking force over time were determined. A comparison of two sets of curves showed a high degree of coincidence, indicating the feasibility of the device in principle. Subsequently, to verify the accuracy of the measurements obtained by the device, a specific firearm was studied through simulation and experimental analysis, demonstrating the precision of the device's measurements. This structural device not only can be effectively used for measuring firearm unlocking force but also provides a new approach for experimental research on this force in firearms.
