Actuator Acceleration
The D-BOX Motion System can produce a 1G acceleration or greater. However, to avoid risks of injury for the user or
damage to the equipment, D-BOX recommends calibrating the Motion System to produce a maximum of
1G, using
the control panel - see information on Motion Core. An acceleration above 1G can make the platform jump. Jumping
can be observed when the actuator takes off from the ground. The following figures show a piston jumping in its cup.
The shock of a piston falling back down in its cup reverberates on the top bearing of the piston, which takes the hit to
protect the motor. As it progressively wears, the bearing also becomes noisier, reducing the service life of the ball
nuts and screw. Avoid actuator jumping in the cup.
This behavior is typical when running the platform with no or light weight. There are no guidelines as to minimum
weight; this is highly dependent on the actuators position, the motion code, the simulator weight, simulator structure
and weight distribution.
Distance between actuators
Respect the minimum distance between actuators for adequate movement of the platform. Measure the distance
from a
square surface enclosing all actuators
- see example below. Respecting the spacing guidelines ensures proper
interaction of the Motion System with the actuator endings, and proper lateral force transfer.
