振动时效技术的认识与实践

Understanding and Practice of Limiting Vibration Time Effect Technique

振动时效是一种采用激振技术施加循环载荷有效降低和均化工件内部应力的技术,相对传统的热时效工艺具有效果好、投资少、成本低、节能减排、灵活性强等特点。随着亚共振技术的完善和频谱谐波技术的发展,应用范围不断扩大,现已广泛使用于机械制造、船舶、航空、航天、矿山机械、燃气轮机、风力发电等行业,取得了良好的社会和经济效益。

Limiting the vibration time effect is a kind of technique that the uibration technique is adopted to carry the cyclic loading to lower effectively and homogenize the inner stress of the chemical engineering parts.Generally speaking,the relative hot time effect technique is characteristic of good effect,little investment,low cost,economy of energy and effluent reduce and perfect flexibility.Along with the second resonance and frequency spectrum techniques perfection and development,this technique is used widely in machinery,ship,aviation,aerospace,mine machinery,gas turbine,wind powrt etc.with perfect economic results in society.
