A Measurement of Oil Film Pressure Distribution in Connecting Rod Bearing With Test Rig

Reciprocating machinery bearing analysis: Theory and practice

“…Holmes concluded that pressure variation was in agreement with theoretical predictions, and that a temperature rise of about 15 K above the supply temperature occurred. (a) an inductive transducer mounted in the connecting rod bearing to measure oil ®lm thickness (and also incorporating a dummy transducer to offset transducer sensitivity to temperature) as used by Goodwin and Holmes [11]; (b) an inductive transducer mounted in the crank journal to measure oil ®lm thickness and extracting the signals via slip rings, as used by Goodwin et al [53] Experimental rigs were used to simulate the load conditions in a big-end bearing by both Hashizume and Kumada [51] and Masuda et al [37] (see Fig. 5c) in independent studies.…”

“…Tanaka noted that relatively little work had been published concerning transient (i.e. dynamically loaded) THD lubrication or EHD lubrication models, but noted the contributions of Paranjpe [32] and Masuda et al [37], who showed the minimum oil ®lm thickness to be at the edges of the bearing where deformation due to lubricant pressure was lower.…”

Experimental Evaluation of Lubrication Characteristics of a New Type Oil-Film Bearing Oil Using Multi-Sensor System

“…Under all comprehensive rigorous experimental conditions, bench testing can realize the operation under different conditions of devices and can intuitively reflect the operating performances of oil. Testing oil-film bearing oil is mainly done on the oil-film bearing test rig [11][12][13]. The final procedure of oil development is the running test, and the test for oil-film bearing oil is required to be conducted on an on-site rolling mill [14,15], but too many influential factors need to be considered, and even the normal production of enterprise will be influenced or interrupted, so it is difficult to implement this method.…”

A test rig to study the performance of water-lubricated high-speed hybrid bearings

“…Masuda et al [1] developed a test rig to simulate the load of an operating engine and measured the oil film pressure distribution in connecting rod bearing. The dynamic characteristics of large journal bearings were identified through electro-magnetic impulse method on a full scale journal bearing test rig by Jianget al [2].…”
