摩擦
摩擦测试确定了两个表面在受到接触力时彼此滑动的难易程度。在这些测试中通常会观察到两个主要现象：静摩擦和动摩擦。静摩擦力是防止物体静止的力，而动摩擦力是当两个表面已经运动时在其间作用的力。Biomomentum开发的软件使用垂直平台施加法向力，而其他阶段施加旋转或平移运动，则可以轻松确定摩擦系数和测试中涉及的力。摩擦测试的目的涉及广泛的领域。例如，测试新型润滑剂的有效性或比较两个样品的表面性能。
FRICTION
Friction tests determine the ease of two surfaces to slide against each other when subjected to a contact force. Two main phenomenons are generally observed during these tests: static and kinetic friction. Static friction is the force preventing an object from moving from rest, while kinetic friction is the force acting between two surfaces when they are already in motion. Using the vertical stage to apply a normal force and the other stages to apply either rotational or translational movements, the software developed by Biomomentum allows you to easily determine the coefficient of friction and the forces involved in the tests. The purposes of friction testing cover a large field of interests. For example, testing the effectiveness of a new type of lubricant or comparing the surface properties of two samples.
