摘　　要：本文介绍了双脉冲激光全息照相对机床结构特性的现场测量技术,并应用它成功地分析研究了压力机整机的动刚度。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.
