Structure Design Method of Torsion Pendulum System Used in Measuring Micro - impulse

摘要

Micro - impulse measurement is a problem needed to be primarily solved in laser micro - thruster research. Micro - impulse measurement with torsion pendulum has obvious advantage. According to the principle of micro - impulse measurement with torsion pendulum, the effect structure parameters of torsion pendulum put onto measurement precision has been analyzed, and design principle of structure and period is brought up, which provides a practicably engineering method.
