数控系统的可靠性是衡量数控系统质量的重要属性,其可靠性结论的得出需要进行规范的可靠性试验。目前,对于MTBF要求在10000 h以上的高档数控系统,其MTBF指标验证在实施上困难较大,试验周期长,亟需一套完整可参考的数控系统可靠性试验方案。根据数控系统与可靠性试验的相关标准与实际产品功能,给出了数控系统可靠性试验条件与方案的参考原则;基于可靠性鉴定试验的基本思路,提出了数控系统可靠性试验的试验条件与试验方案,并且给出了典型的组合环境试验剖面和运行试验剖面,为数控系统的可靠性试验提供了通用参考。
數控繫統的可靠性是衡量數控繫統質量的重要屬性,其可靠性結論的得齣需要進行規範的可靠性試驗。目前,對于MTBF要求在10000 h以上的高檔數控繫統,其MTBF指標驗證在實施上睏難較大,試驗週期長,亟需一套完整可參攷的數控繫統可靠性試驗方案。根據數控繫統與可靠性試驗的相關標準與實際產品功能,給齣瞭數控繫統可靠性試驗條件與方案的參攷原則;基于可靠性鑒定試驗的基本思路,提齣瞭數控繫統可靠性試驗的試驗條件與試驗方案,併且給齣瞭典型的組閤環境試驗剖麵和運行試驗剖麵,為數控繫統的可靠性試驗提供瞭通用參攷。

Reliability is an important attribute to measure the quality of CNC system.The reliability conclusions are drawn ac-cording to regular reliability test.At present,for CNC system which MTBF requires a high index of more than 10 000 h,the authenti-cation of MTBF in its implementation is quite difficult,such as long period of time testing.Therefore a set of complete CNC system re-liability test program for reference is much-needed.According to correlative standards and product functions of CNC system and relia-bility test,some principles of reliability test conditions and test programs were given,and the test conditions and test programs were proposed based on the thought reliability compliance test.A typical combined environmental test profile and run test profile were given. The research provides common reference for CNC system reliability test.
