Embodiment Construction
[0035] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.
[0036] The invention relates to a method for verifying a finite element thermomechanical coupling model of high-energy beam additive manufacturing. The finite element thermomechanical coupling model is verified by using the heat-deformation-strain field measurement results obtained through real-time measurement by a data measuring device.
[0037] The following embodiments take the laser beam in the high-energy beam as a representative to illustrate how the present invention realizes the in-situ real-time accurate measurement of the heat-deformation-strain field by using the data measuring device in the high-energy beam additive manufacturing process and applies it to thermal-mechanical coupling Model validation. Such as figure 1 As shown, in the high energy beam processing process, the ther...
