隔振器过载振动复合环境试验研究

Research on Dampers′ Acceleration-Vibration Environment Test

目的为了对试验产品的过载振动复合环境进行充分的考核,同时兼顾经济性和便捷性。方法选取橡皮绳、振动台系统进行过载复合环境试验,并分析橡皮绳、振动台系统的可行性,讨论其应用范围。结果从橡皮绳的拉伸曲线可以看出,橡皮绳的变形在5%以内刚度较大,变形超过5%刚度较小。在橡皮绳较小刚度区间,对隔振器进行振动试验,结果很好。结论采用橡皮绳、振动台系统进行隔振器过载复合环境试验不仅能够节省成本,缩短试验周期,而且能够达到很好的试验效果。

Objective To fully test the acceleration-vibration environment economically and conveniently.Methods This paper used rubber ropes and a shaker to simulate the acceleration-vibration test, analyzed the feasibility of the method and discussed its application scope. Results Rubber rope＇s tension test showed that it had high rigidity with less than 5% strain and low rigidity with more than 5% strain. While rubber rope was in the region of low rigidity,damper＇s acceleration-vibration test had very good results. Conclusion The results proved that applying this method could reduce the test cost, shorten the test period and achieved the test goal.
