Hole quality in longitudinal–torsional coupled ultrasonic vibration assisted drilling of carbon fiber

Guofeng MA, Renke KANG, Zhigang DONG, Sen YIN, Yan BAO, Dongming GUO

Frontiers of Mechanical Engineering 2020, Volume 15, Issue 4, Pages 538-546 doi: 10.1007/s11465-020-0598-y

Abstract: The advanced longitudinal–torsional coupled ultrasonic vibration assisted drilling (LTC-UAD) method hasa potential application for drilling CFRP composites.At present, LTC-UAD is mainly adopted for drilling metal materials and rarely for CFRP.Therefore, this study analyzes the kinematic characteristics and the influence of feed rate on the drillingThus, LTC-UAD is an applicable process method for drilling components made with CFRP composites.

Study on shaft drilling and blasting construction risk analysis and countermeasures of Bohai Strait tunnel

Zhang Wenxin and Zou Chong

Strategic Study of CAE 2013, Volume 15, Issue 12, Pages 101-106

Abstract:

In view of the shaft construction risk analysis of Bohai Strait tunnel, this paper determines risks during construction. Combining the risk weight analysis ranking,the sequence in turn from low to high is supporting structure failure risk, natural disaster risk and shaft excavation risk. Through risk assessment,we determine that the risk of water inrush and mud outburst is the key risk. Considering the influences of key risk and other risks on the shaft construction,we put forward response measures about shaft construction risk of Bohai Stiait tunnel from the geological forecast,shaft hoisting equipment selection and hoisting process control, shaft excavation risk control, natural disaster risk prevention, shaft supporting structure for quality control and the establishment of the shaft system construction,which provide guidance for the subsequent construction.
