Flat Bed Friction Testing To measure Static and Dynamic coefficients of friction it is necessary to use a fixed bed instrument. These instruments use a motor to pull a sled across the sample, using a load cell to measure the forces. Original slip testing instruments were converted tensile testers that used a cord to pull the sample.

See YouTube video. Reciprocating Sliding Friction and Wear test. The Reciprocating Sliding Friction and Wear test can be used to measure average coefficient of friction (COF) and wear. It is possible to perform dry and lubricated tests. The variation of friction force between upper test specimen and nether test specimen is very complicated on the reciprocating wear tester. There are many factors exerting influence on it. Based on the bench test, a system is developed for measuring the variation of the friction force between upper and nether test-piece.2.3 Tribological test The tribological tests were performed on a reciprocating friction and wear monitor test rig (TR-281M-M6) for a cylinder liner and piston ring as shown in figure 1. Piston ring is movable and slide on the surface of cylinder liner which is stationary. A bottom heating unit is used to heat the friction pair. Approximately 2drops
range of mechanisms, including reciprocating engines and pumps (Mccarthy 2018). The principle of operation of a linear reciprocating tribometer consists of sliding test samples against a stationary counter surface under load and recording the parameters of interest (Mohan et al. 2009). With this tribometer, it will be possible to measure friction

To facilitate the in-depth study of the tribological behavior of texture friction pairs in the process of reciprocating friction. The micro-displacement deformation output model of compliant mechanism is deduced using a new method for indirectly measuring friction coefficient through micro-deformation of double parallel four-bar compliant mechanism. Then, the whole structure .Friction coefficient and sliding speed under 150 N load According to a general overview of the results as test conditions (time, speed, and load) and a high coefficient of friction considered to be obtained, though reciprocating friction test apparatus has a small oil tank, boundary lubrication and/or mixed lubrication regimes. In the pin-dish sliding wear test, at room temperature, under 20 N test, the friction coefficient of the sample with rough lamination/smooth lamination/resin carbon is 0.13 and the mass wear loss .

Historical/Traditional Test Geometry. The classic work of Thurston 1, Martens 2, Stribeck 3 and Hersey 4 were done using a journal-bearing geometry, which possesses all of the above requirements (Figure 3). An instrumented journal-bearing test allows for evaluation of the friction over a range of relative velocities and/or loads.The Japanese test standard is 100 times of reciprocating friction, while other reciprocating friction is only 10 times, which is a huge difference. Therefore, the total contact area and the total course of the Japanese standard friction test should be long, so the friction colour fastness test results are the worst, and the test method is the .
Integrating the capability for high cycle, long duration reciprocating nano-/micro-scale tests into a commercial instrument extends the versatility of the multi-functional test instrumentation. In reciprocating tests noble metal-noble metal contacts (Au–Au and Ag–Ag) showed much longer endurance than gold vs. steel contacts.
