Avoiding mistakes when sizing pneumatic rodless actuators is the result of first-hand knowledge gained through applications experience with rodless cylinders.
Tol-O-Matic, as a company, actively tracks the most common mistakes that their customers encounter when sizing rodless linear actuators. This technical paper focuses on pneumatic rodless cylinders (specifically band type) and is the first in a series of topics on the sizing and selection of rodless linear actuators/cylinders.
Here is the list of most common mistakes that engineers make when sizing rodless actuators.
Overestimating the available air pressure
Incorrectly determining the actuator's working stroke and overall length
Under or over sizing the cylinder
Not considering the effects of resulting moments (torques)
Overlooking the effects of dynamic moment loading
Not understanding the importance between average and impact velocity
Incorrectly determining the cushion or shock absorber capacity
Not factoring in the effects of motion lag due to breakaway, acceleration and friction forces.
A recent example of a major CAE revamp is MSC Apex, released last month by MSC Software Corp. In a discussion with Design News, MSC executives noted that its next-generation platform is designed to substantially reduce CAE modeling and process time, “in some cases from weeks down to hours.”
The Thames Deckway would run for eight miles close to the river’s edge, rising and falling slightly with the tidal cycle. It will generate its own energy from a series of devices that will line the pathway and use a combination of sources to make the path self-sustaining.
