Triboster is Kyowa’s measurement instrument for coefficients of static/kinetic frictions, with a horizontal linear reciprocating motion system.
Analysis Method
The graph shows the variations of the Friction Coefficient over time. The Coefficient of Static Friction μs is determined by the peak between (A) - (B), and the Coefficient of Kinetic Friction μk is determined by the average between (B) - (C).
Friction of coefficient
Moving the stage while applying a vertical load to the contact part (upper sample), generates the Frictional Force F between the upper and the lower samples. In this condition, the Friction Coefficient is given by the equation μ = F / W.
