Dynamic isolation test and analysis of a zero-spring-rate mechanism
Abstract
Results of a NASTRAN model analysis of the zero-spring-rate mechanism (ZSRM), a candidate motion isolator device for the Space Station Freedom, are reported. The results confirm the deterioration of the isolation performance due to spring surge and other mechanism modes and demonstrate the importance of low damped (less than 0.5 percent) modes in degrading the expected theoretical performance. It is noted that further evaluation is required to determine the suitability of the ZSRM for use as an isolation device.
