液压支架连杆结构件“频谱谐波时效”的工艺研究

Process Research of "Spectrum Harmonic Wave Ageing" of Hydraulic Support Connecting Bar Structure

研究了液压支架连杆结构件采用"频谱谐波时效"消除残余应力的影响因素,提出了采用"频谱谐波时效"消除残余应力的工艺技术参数,并对连杆振动时效前、后的应力均化情况进行了检测与评定。频谱谐波时效与传统的热时效相比的经济效益分析。

The influencing factor of cancel the remnant stress was researched, and about hydraulic support connecting bar structure use the way of ＂spectrum harmonic wave ageing＂. The process technical parameter which use the way of ＂spectrum harmonic wave ageing＂ cancel the remnant stress was advanced. The situation of connecting bar ageing which about the counterpoised by the stress was checked and assessed. The economic benefit between the spectrum harmonic wave ageing and the traditional heating aging was analysed.
