Application of Pulse Laser Holography in Analysing Dynamic Rigidity of a Forging Press
脉冲激光全息技术用于锻压机床动刚度分析

A Technology for testing the behaviours of machine tool structure in field by double-pulsed laser holography is introduced. It is the first time in China that the dynamic rigidity of a whole forging press has been successfully obtained and analysed with this approach.
