Force analysis and simulation – experimental research on the measurement of cylindrical surface profiles

The results of tests presented herein can have practical applications for the adjustment of rotary speed to ensure constant contact between the measuring sensor’s spindle tip and the crankshaft journal of a piston energy converter, whose roundness profile is being measured. Analytical considerations have been supported by the results of simulations as well as experimental tests. The research has also shown that an increase in rotary speed affects the obtained profile shape and the value of determined roundness deviation.
