沙发耐久性测试仪
Sofa Durability Tester
沙发的力学性能试验主要是试验沙发的座，背，扶手的耐久性。试验时将一定形状，质量的加载模块，以规定的加载形式，频率，分别对座，背，扶手表面重复加载。
It is used to teting the sofa back, seat,arm’s durability. Use a loading with specificed form,frequency to repealty load on seat, back and arm suface loading
这一试验方法是模拟日常使用情况下，沙发对长期重复性载荷的承受能力。
. This test method is to simulate everyday use, the sofa on the long-term repeatability of the load bearing capacity.
 本机采用触摸屏和PLC编程控制。可对所有加载频率，加载力度进行编程控制。
The machine adopts PLC touch screen and the program control. Can all loading frequencies, loading control the intensity of programming.
采用最合理的调节结构。
The most reasonable regulation structure.
