Dynamic Seam Fatigue Tester

Применение:

Thesewn seam dynamic fatigue testing machine is designed to evaluate the fatigue resistance of seam on the material which is applied on the surface of automotive seat. The surface material of car seat (leather, synthetic leather, fabric, etc.) is often stitched together. The stitching strength of the material seam and the fatigue strength of the seam can directly affect the service life of the seat. The strength and life of the joint of the test material can effectively predict the life of the seat and provide the direction of improving the service life.

Информация о продукции:

Theмашина для испытания сварных швов на усталость is a two station bench top machine, used for evaluating fabric or leather seating materials resistance to tearing or needle hole elongation of a sewn seam. Each station includes a pair of suitable clamps for attaching the test sample. A height gage is used to set the sample clamp separation distance of  the 140mm for each station.One or two stations can be tested at a time.


 

Образец помещается на приспособление, а расположение правого и правого зажимов приводит расстояние между тестируемыми образцами в соответствие со стандартными требованиями. Set the test cycle numbers and start the test. The Decelerator will drive the middle clamp holder to do the reciprocating movement. The left and right clamp holders are connected with a 3kg load.

During the reciprocating motion of the middle clamp holder, the left and right samples will experience a process of loading and unloading of the weight load at the time of around one motion cycle. 

TheПереключатель приближения подключен.Счетчик регистрирует цикл движения зажима, и тест автоматически останавливается, когда достигается заданное количество циклов. Устойчивость к усталости соединения измеряется путем измерения изменения отверстия шва в шве материала.
