A worm spring torsional pendulum is developed.

A new method using torsion pendulum to verify the parallel axis theorem;

The design of a capacitance driving type negative feedback control system for a torsion pendulum accelerometer

A large measurement system of moment of inertia based on air-hovered turn-table is developed according to the theory of testing moment of inertia using torsion pendulum.

Double hanging torsional pendulum auto-measuring instrument for rotational inertia;

The torsional pendulum experiment is set up in order to extend the curricula of experiments of nonlinear system.

The results show that the fracture of torsion spring was mainly caused by hydrogen embrittlement.

The cause that the misfiring rate of fail-safe in the sub-munition fuze of the cargo projectile is abnormally high is analyzed,and the method by adding pre-torsional moment of the torsion spring and adjusting the mass center of the rotor is adopted to optimize the rotor of the sub-munition fuze,which based on quality characteristic and measuring tool to create SolidWorks modeling program.

In this paper, the application and the mechanism principle of torsion spring overrun clutch are introduced.
