Assignment#1 Survey on sensors and actuatorsSlide-4To explore further (survival pointers of web references etc) •When searching for a specific type of pneumatic cylinder it is easiest to go directly to a manufacturers website such as www.parker.com.•If searching for a specific type of pneumatic cylinder, type in the specifics of the pneumatic cylinder to weed out the nonsense websites.•Or find a website that lists the most popular manufacturers of pneumatic cylinders.01/13/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuatorsSlide-5Major applications •Manufacturing.•Clean room environments.•High force applications.•Food processing plants.•Fast response systems01/13/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuatorsSlide-6Pnuematic Cylinder ApplicationsPneumatic cylinders (positioned horizontally in background with rod end facing left) actuate trim saw blades to cut up to 20 pieces of lumber per minute. Cushioning of pneumatic cylinders is crucial to this high production rate.01/13/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuatorsSlide-7Pnuematic Cylinder ApplicationsMotorcycle shocks are a pneumatic cylinder that uses pressurized air and oil in order to dampen vibrations from roads and or jumps. This type of pneumatic cylinder is used in almost all automobiles and vehicles. Some pneumatic cylinders for automobiles are controlled by letting air in or out of the cylinder depending on the conditions.01/13/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuatorsSlide-8Pneumatic Cylinder ApplicationsA couple of very large pneumatic cylinders push this ride that seats 20 people per boom. This ride along with many others made in Logan, Ut use giant pneumatic cylinders to make the ride go.01/13/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuatorsSlide-9Pneumatic Cylinder Major Specifications• Operating pressure range (min/max).• Piston bore size.• Piston stroke (how far the piston moves).• Mounting options.• Overall size.01/13/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuatorsSlide-10How Pneumatic Cylinders WorkAs shown in the picture below, pneumatic air cylinders work by using compressed air that is input to one side of the cylinder which in turn pushes a piston in or out. Some pneumatic cylinders have a spring on one side so that it does not require air to push it back.01/13/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuatorsSlide-11Pneumatic Cylinder Benefits• Pneumatic cylinders can operate at very high speeds depending upon the pressure that is used and the mass of the rod and piston that is being moved• They are easy to maintain and repair, unlike hydraulic cylinders, when the cylinder needs to be rebuilt you don’t have the mess of oil all over. Plus if there is a leak in the system it doesn’t make a greasy mess• They are forgiving when taking an impact.• Small quick connect hoses can be used that require no tooling to put together.01/13/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuatorsSlide-12Pneumatic Cylinder SelectionThe selection of the pneumatic cylinder is quite simple. First off you need to know the types of forces involved in your design. Then you need to decide what types of pressures the system can supply. Then you choose the proper stroke and piston diameter to meet the needs of the system. This can be an iterative process especially if the system pressure isn’t constrained too much. Size can also be an important factor in the iterative process.01/13/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuatorsSlide-13Pneumatic Cylinder Limitations• Pneumatics cylinders can have overshoot and are not very accurate if used at low pressures.• They can be extremely noisy because of the escaping air that is wasted into the ambient air.• They require a large storage tank to supply the necessary air for the cylinder to achieve repetitive movements.• Forces are not as high as a hydraulic cylinder of the same size.• In order to make it portable you must have a compressor to supply the air.01/13/19ECE5320 Mechatronics.
