Research on the Control Method for Preventing Secondary Impact in the Ball Drop Test of Ultrathin Glass
With the continuous development of digital technology,electronic devices such as mobile phones and tablets have become indispensable tools in production and daily life.The cover glass on such equipment is a weak link in daily use,frequent occurrence of accidental fragmentation.This is determined by the impact strength of glass materials.Researched on the falling ball impact method specified in the national standard GB/T 39814-2021,automatic control scheme for forming anti secondary impact devices,avoid secondary impact on the glass sample during the drop ball impact test,ensure the accuracy of experimental data,and reduce experimental costs.
