Performance prediction of D-Strut isolation systems

摘要

Abstract: Dynamic models and simulation results are presented for D- Strut$+TM$/ isolators. The D-Strut is a passive spring-damper device with space flight heritage used for vibration isolation. Detailed models are presented for both hydraulically and pneumatically damped D-Struts and the performance achieved by each will be compared. All of the models presented are single degree-of-freedom with a mass isolated from base motion by one isolator element. A simulation program was used to investigate the frequency domain and time domain dynamic response of the D-Strut models. The results are presented. !4
