The hydraulic systems are widely used in industry, but they would inevitably give rise to some failures. Firstly, this paper describes some hydraulic system failures in a reliability test. Secondly, it makes a detailed analysis for the reasons of failure. Lastly, some corresponding solutions are given for the different failures.
Firstly, this paper conducted the failure modes and effects analysis (FMEA) for the certain hydraulic system; secondly, it calculated the impact load of the hydraulic system when it works; and based on above results of FMEA and the calculation of impact load, it has made the finite element analysis to key components in Abaqus which caused most failures. Finally, it optimized the design of the sealing...
