The simulation analysis of stress and stress relaxation is done on the M-shape of the clock-spring on steering-wheel with the general finite element analytical software MARC as a diagnostic tool.

Taking the M-structure of the clock-spring on steering-wheel as the subject of studying, using finite element analysis software MARC as analysis tools, the stress & stress relaxations of the M-structure are simulated and analyzed, and the design of the M-structure is optimized based on the analytical results.

Design of novel dual-channel optical rotary joint by using de-rotating prism;

A new dual channel optical rotary joint has been proposed by infrared coupling technique to transmit optical signals across rotational interfaces to ensure continuously transmitting signal.

A novel multi-channel optical rotary joint using square-cylinder de-rotating prism was proposed based on analyzing the principle and conditions of de-rotating prism used in multi-channel optical rotary joint.

Design of fiber optic rotary joint based on photonic crystal fiber;

Single channel fiber optic rotary joint has simple structure, small size and low optical losses, but the unidirectional transmission limits its wide applications.
