Abstract
Systems and methods that characterizes a load as a function of position/movement of mechanical components—as induced by such load in the servo-drive system. By running a plurality of motion profiles, corresponding torque/forces that generate such motions can be calculated and readily represented (e.g., as a table) in form of a position dependent load. In addition, a parsing component can decompose or break up a load (which generates a desired motion) to its subparts or constituent values for further simulation analysis.
Claims20
An industrial automation system, comprising:
- an analysis engine configured to calculate a force associated with a mechanical member of a servo driven mechatronic system based on an analysis of a motion profile of the mechanical member;
- a representation of the force as a function of motion induced by the force in the mechanical member;
- and
- a simulation component configured to simulate the operation of the servo driven mechatronic system based on the representation.
A method for simulation in an industrial automation environment, comprising:
- receiving a motion profile for a servo-motor system from a computer aided design (CAD) system;
- calculating one or more loads that are generated on one or more components of the servo-motor system based on analyzing the motion profile;
- and
- simulating operation of at least a portion of the servo-motor system based on the one or more loads, without communicating with the CAD system during the simulating.
A computer readable storage medium comprising computer-executable instructions that, in response to execution by an industrial automation system, cause the industrial control system to perform operations, comprising:
- calculating a load that is to be applied to a servo driven mechatronic system to induce a designated motion thereon;
- representing a one-to-one correspondence between the load and the designated motion;
- and
- utilizing the one-to-one correspondence to facilitate a simulation of the servo driven mechatronic system.
