| Summary: | Real mechanical systems are characterized by real parameters,
which include primary manufacturing and assembly errors, force
and temperature deformations, and abnormal operating modes,
the full knowledge of which is unknown when designing systems.
Incomplete knowledge about the object is compensated by using
coefficients entered into calculation formulas. The coefficients
form the basis of reference literature and are obtained on the
basis of generalization of experience in creating objects that are
similar in design and purpose. This statistical technique is used
to increase the margin of safety, but it does not allow us to obtain
optimal performance criteria for the design of mechanical drives
in particular.
It is proposed to use the principle of designing mechanical systems
by giving them the property of adaptation to real parameters at
the design stage. The means of adaptation is an additional motion
of links to the main one, implemented in particular by functional
compensators. An algorithm for the synthesis of a compensator is
given on the example of the basic scheme of a friction planetary
gearbox. |
