AI Technical Summary

Technical Problem

Conventional simulation techniques struggle to accurately reproduce the movement speed of actuators like air cylinders and hydraulic cylinders in simulation models due to the lack of sensors to directly detect this speed, making it difficult to set appropriate simulator parameters.

Method used

A simulator that calculates the movement speed of a movable part based on start and end times of movement recorded in an operation log, without direct measurement, using a time acquisition unit, calculation unit, and setting unit to set simulator parameters.

Benefits of technology

Enables accurate setting of simulator parameters by calculating movement speed from operation log data, allowing the simulation model to closely mimic the actual device's behavior, even with varying loads and actuator states.

Abstract

This technology provides a way to calculate the movement speed of a movable part of an actuator in an actual device without directly measuring its movement speed, thereby enabling the appropriate setting of simulator parameters. [Solution] The simulator 2 comprises a time acquisition unit 50, a calculation unit 60, and a setting unit 70. The time acquisition unit 50 acquires the start time and end time of movement of the movable body from the operation log 22 of the actual device 1. The calculation unit 60 calculates the movement speed of the movable body based on the start time and end time of movement acquired by the time acquisition unit 50. The setting unit 70 sets parameters related to the movement speed of the movable body of the simulator 2 based on the movement speed calculated by the calculation unit 60.
