                                        簡述疲勞試驗設備的應用

                                        2012-04-24 0

                                        所謂疲勞試驗,是指使試樣或構件承受周期或隨機變化的應力或應變,以測定疲勞極限和疲勞壽命等指標的試驗。

                                        疲勞試驗機特點是可以實現高負荷、高頻率、低消耗,從而縮短試驗時間,降低試驗費用。

                                        疲勞試驗常用于進行測定金屬、合金材料及其構件(如操作關節、固接件、螺旋運動件等)在室溫狀態下的拉伸、壓縮或拉壓交變負荷的疲勞特性、疲勞壽命、預制裂紋及裂紋擴展試驗。高頻疲勞試驗機在配備相應試驗夾具后,可進行正弦載荷下的三點彎曲試驗、四點彎曲試驗、薄板材拉伸試驗、厚板材拉伸試驗、強化鋼條拉伸試驗、鏈條拉伸試驗、固接件試驗、連桿試驗、扭轉疲勞試驗、彎扭復合疲勞試驗、交互彎曲疲勞試驗、CT試驗、CCT試驗、齒輪疲勞試驗等。

                                        我司專業生產脈沖疲勞、壽命疲勞等相關疲勞試驗設備,歡迎來電咨詢!
