Study on the measurement of force parameters in vibration test

At present,the force limited control technology has become a standard on spacecraft dynamic environment test at NASA and ESA.Its main purpose is to reduce the probability of over test.Our aerospace departments also perform studies on this field.That how to guarantee the measurement of force parameters in force limited vibration test is a part of key technique.This paper introduces the measurement process of the multi-axis force parameters.Also,the measurement result and data analysis are presented.This paper is to summarize the technology of force parameters measurement using the FMD and acquire the experience for developing the study on measurement the force parameters.
