A real-time analysis method for sliding motion trajectory of dovetail groove mold core

Abstract

The application provides a dovetail groove mold core sliding motion trajectory real-time analysis method, including: according to the slope value of the deceleration section of the speed curve, adopting a support vector machine algorithm for classification processing, identifying the steepness level of the slope, and triggering an impact level evaluation process when the steepness level of the slope is higher than a preset threshold; according to the steepness level of the slope, combining the impact force peak duration evaluation kinetic energy release time window, identifying the pulse impact level; according to the pulse impact level and the slope extrusion force amplitude, extracting the impact force peak curve characteristics and determining the critical boundary identifier; according to the dynamic adjustment of the critical boundary identifier, the determination reference is adjusted, the adjusted determination reference is applied to the speed curve analysis, the mold core arrival stable time prediction value is identified, and the determination reference is optimized and adjusted when the prediction value exceeds the preset range; the mold core sliding motion trajectory is monitored in real time by using the optimized and adjusted determination reference, and the accuracy of the mold core arrival is determined.
