Abstract

A frictional wear test system is provided by the invention, and comprises a base, a vibration exciter, a stroke push rod, a heating table, an oil box, a loading mechanism, a first displacement sensor, a force measuring mechanism, a vibration isolation supporting plate, a second displacement sensor and a control system. The vibration isolation supporting plate is arranged on the base in a floating mode, and the heating table is arranged on the vibration isolation supporting plate through an elastic support. The second displacement sensor is arranged on the vibration isolation supporting plate and configured to measure second displacement generated between the stroke push rod and the vibration isolation supporting plate. The control system is electrically connected to the first displacement sensor, the second displacement sensor and the vibration exciter, and the control system is configured to calculate feedback values of the stroke and the frequency of the stroke push rod according to the first displacement and the second displacement and compare and analyze the feedback values with preset values so as to control the vibration exciter to output the preset stroke and the preset frequency.

Description

technical field [0001] The present disclosure relates to the technical field of friction and wear tests, in particular to a friction and wear test system. Background technique [0002] For the evaluation method of diesel lubricity, the latest international standard is ISO 12156-1:2016, and the domestic industry standard is SH / T 0765-2005. At present, China has been able to produce high-frequency reciprocating testing machines that meet the above two standards for the detection of diesel lubrication performance. In 2017, the SH / T 0765 standard drafting unit united with 57 laboratories, using 8 representative diesel samples, and conducted more than 500 blind tests on more than 70 high-frequency reciprocating diesel lubricity testing machines of three brands at home and abroad. Measure comparison test. Statistics show that the development level of the existing high-frequency reciprocating testing machines in China is uneven. The technological innovation mainly focuses on the ...
