摘要

This report presents an account of the activities of the MERADCOM-OSU System Reliability Program in the area of hyraulic cylinder structural integrity assessment. A dynamic mathematical model of the locked-rod or impulse testing is developed and the effects of changing test setup parameters are also demonstrated. A computer program for simulating locked-rod testing is presented along with a user's guide. Draft procedures for both stroking (endurance) and locked-rod (impulse) tests are included in an appendix. Results of experimentation with locked-rod setup are also presented. This report presents the data obtained from the On-Board Monitor activities. These data are a result of endeavors on two projects--On-Board Monitor and Operational Severity. STAM units were installed on a variety of vehicles. As many as five parameters per vehicle were monitored with several tests repeated with multiple runs. (Author)
