		Mechanical and System Safety Research Group

To prevent mechanical accidents, the Mechanical and System Safety Research Group investigates the strength evaluation for pressure vessels and structures, the application of failsafe techniques for automated machines, the development of new systems requiring the human-machine interface, and the applications of artificial intelligence.

1. Fracture prevention of materials

To obtain the fundamental date for fatigue fracture, fatigue crack propagation properties of materials under various conditions are evaluated by means of fracture mechanics and fractography. Non-destructive detection techniques for defects in materials are also studied.

Experiment name

	Stress analysis by infrared-ray measurement.
	Assessment of fatigue strength on structural components.

2. Safety requirements for lifting and construction appliances

To establish the requirements for the design of lifting and construction appliances, the effect of loads and stress frequency on cranes is analysed, and the methods of evaluating the strength of members are studied.

Experiment name

	Bending fatigue test of wire rope.
	Measurement of vibration characteristics on jib crane.

3. Safety requirements for machines and equipment

For the prevention of mechanical accidents caused by machine failure or inappropriate operation, the technological fundamentals of failsafe systems are studied, and the findings are applied to interlocking models, industrial robots, and other equipment. Investigations are also carried out on the development of self-checking systems in the event of machine failure, and other advanced safety control systems.

Experiment name

	Interlocking model using various door switches.
	CNC lathe with safety-controlled PSDI (Presence Sensing Device Initiation).

4. Safety requirements for human-machine interface systems

Research is conducted on new types of machines and equipment, including the development of robotic systems with inherently safe actuators and safety controls that are helpful for elderly or handicapped workers. Human-machine interface systems that are based on new concepts of efficiency of work and ease of operation are also studied.

Experiment name

	New robot actuator using smart fluid.
	Cooperative work by construction robot.
