背景介绍:
机械压痕是一种快速、无损的生物组织评价技术。近,Biomomentum对这项技术进行了改进和扩充,它既具有映射绘图能力,又解决了垂直性问题,这仍然妨碍了纳米压痕等其他方法。利用这些突破,新的研究设计的效率大大提高。压痕通常要求被测试的表面是平坦的,并且还需要垂直于关节表面的压缩轴。多轴机械试验机MACH-1 V500 CSS的3D“正常压痕”函数地检测XY位置处的表面高度和方向,并记录载荷(多轴向载荷单元),同时以不同速度移动测试仪的三个阶段,以便以预定义的方式移动球形压头。沿着垂直于样品表面的虚拟轴的位移分布。利用MACH-1 V500 CSS测试器*的多轴能力,生物显微镜已经开发出新的功能,允许压痕测试的所有优点,同时克服了传统的局限性。这一技术进步依赖于在Mach-1运动软件中增加两个功能:“扫描XY”和“正常压痕”。在每个位置执行一系列功能之前,“扫描XY”功能在预定义位置移动测试仪的X和Y水平级。应该提到的是,这样的位置列表可以很容易地生成使用Biomomentum的“软骨映射”软件处理样本的俯视图。“正常缩进”函数地检测出XY位置上的表面的高度和方向,并记录负载(多轴载荷单元),同时以不同的速度移动测试仪的三个阶段,以便沿着一个正常的法线的虚拟轴在样品表面移动球形压头。
