目前,Instron公司生产的电液伺服疲劳试验机在我国已较为普及。虽然机器的0~100%Transducer Full Range已能使机器的测力范围从满量程的100%分别扩展至50%,40%,25%,20%,10%,5%,但若只拥有一台Instron机,某些课题仍不能进行或...目前,Instron公司生产的电液伺服疲劳试验机在我国已较为普及。虽然机器的0~100%Transducer Full Range已能使机器的测力范围从满量程的100%分别扩展至50%,40%,25%,20%,10%,5%,但若只拥有一台Instron机,某些课题仍不能进行或达不到很高的精度。有的单位为了适合不同试验对测力范围的不同要求,用外汇购买了两台甚至多台荷载吨位不同而其他功能均相同的Instron试验机,以满足科研和生产的需要。展开更多
英国Instron欧洲总公司针对产业用纺织品用纤维(包括芳纶和超高相对分子质量聚乙烯纤维)过早失效的问题,专门研发了一种简单的解决办法。Instron绳索及纱线气动夹持装置(2714-04x)(图1),测力范围达2 k N,装置中可更替的夹紧块能...英国Instron欧洲总公司针对产业用纺织品用纤维(包括芳纶和超高相对分子质量聚乙烯纤维)过早失效的问题,专门研发了一种简单的解决办法。Instron绳索及纱线气动夹持装置(2714-04x)(图1),测力范围达2 k N,装置中可更替的夹紧块能够适应传统纤维或新近开发的高性能纤维及其制成的纱线。展开更多

The surface change of fabrics before and after abrasion was stu-died by means of scanning electron microscope. With the increasing number of cycles, the re-covery behavior of the fabrics studied in tensile, shear and bending deformation decrease, theantibuckling ability lowers, the friction coefficient increases. The geometric roughness de-creases during the first step of abrasion then enhances with further abrasion. The influence ofabrasion on mechanical properties of the pure wool fabric are larger than that of blend fabric.展开更多
