ZHAI Bin, MA Bo, SUN YaLing. RESEARCH ON KINETIC FEATURES OF THE THREAD LOOSENESS FAULT IN THE CONNECTION BETWEEN PISTON ROD AND CROSSHEAD OF THE RECIPROCATING COMPRESSOR[J]. 2016,38(6):1149-1155. DOI: 10.16579/j.issn.1001.9669.2016.06.002.
Regarded as one of the major faults,the screw looseness fault in the connection between piston rod and crosshead was studied. To simulate the thread looseness failure,a multi-body dynamic model of the reciprocating compressor motion was created. It draws a conclusion that the change trends of the average settlement value and the peak-peak value can reflect the extent of thread loosening failure. Compared with the actual failure cases,the dynamic model is proved to be reasonable.
