Paper Abstract

This paper presents an experimental testing system for identification of linear oil-film dynamic coefficients. The testing system consists of a complicated mechanical test rig, a series of electric driven devices and an electronic measurement system. The theory of the testing system, the construction of the system and some measurement techniques are studied in the paper. The mathematic model of the test is derived from a first-order Taylor series expansion of oil-film force formula. Using the data, acquired by the testing system from experiments, the linear oil-film force coefficients can be recognized. The recognized coefficients are valid. The experiments indicate that the testing system is feasible, the design of the test rig is effective and the electric measurement is accurate.
