About Referencing Characteristic Graphs
The following is an overview of how to reference Pneumuscle's characteristic graphs.
As an example, let us assume that an object weighing 1 kg is to be lifted using a Pneumuscle of Size 20.
To lift a 1 kg object, a traction force of about 10 N or more is required.
When a Pneumuscle contracted by applying air pressure of 0.3 MPa is stretched to the point where the contraction rate is about 7% or less, it means that a traction force of 10 N or more is generated (see the dotted line in the figure below).
The distance an object moves depends roughly on the length to which the Pneumuscle contracts.
It is a good idea to select the drive length so that 7% of the drive length is the height to be lifted.
(Example: If you want to lift an object weighing 1 kg by 10 mm, this is how it is calculated so that 7% of the drive length is 10 mm.
the drive length A[mm]×0.07=10[mm] ⇔ A≒143 mm)
