节约能源这项策略持续执行至今,但在材料试验尤其是疲劳试验领域中依然是一个有待解决的重大课题。例如汽车、船舶和飞机等制造业,为提高产品的经济性而大量地采用了新材料以期降低整机结构的重量并充分发挥发动机的效率。为正确评价这些新材料的性能,研究人员们对疲劳试验机提出了新的、更为苛刻的要求,希望新型机应具备良好的动态特性和高精度,并能真实地再现新材料的使用状态且造价低廉。试验机生产厂应当满足这些要求,在结
The strategy of energy conservation continues to be implemented to date, but remains a major issue to be solved in the field of material testing, especially fatigue testing. For example, manufacturing industries such as automobiles, ships and aircrafts have adopted a large amount of new materials to improve the economy of their products in order to reduce the weight of the entire machine structure and give full play to the efficiency of the engine. In order to correctly evaluate the performance of these new materials, researchers put forward new and more stringent requirements on the fatigue testing machine, hoping that the new machine should have good dynamic characteristics and high precision, and be able to truly reproduce the use status of new materials And low cost. The test machine manufacturer shall meet these requirements at the end
