The application of improved signal summing method into the spacecraft force limited vibration test

摘要：

　　This paper provides an improved signal summing method for the spacecraft force limited vibration test system with eight force transducers.The key point for this method is to change the combination way of the signals coming out of the eight force transducers while the formulas inside the signal conditioning amplifier have been used skillfully.This method had been successfully adopted in the spacecraft force limited vibration test and the accuracy requirements of key force and moment signals have been met.And this method has been proved to be a very powerful tool for providing the critical force and moment data used to determine the force limited profile during the spacecraft dynamic test.
