AI Technical Summary

Technical Problem

Existing motion simulators require three-phase power due to high peak power demands, making them costly and difficult to install in environments with only single-phase power, and there is a need for portable high-fidelity simulators in various locations without access to three-phase power.

Method used

A hybrid motion simulator design using a battery arrangement, smart battery charger, and battery management system that allows operation with single-phase power by storing energy for high power demands and providing backup during power outages, utilizing an energy storage system (ESS) to smooth voltage fluctuations and enable safe shutdowns.

Benefits of technology

Enables high-fidelity motion simulation in a wider range of locations with single-phase power, improving installation flexibility and safety, and extends the battery life by maintaining optimal charge levels, reducing the need for three-phase power infrastructure.

Abstract

A hybrid motion simulator (100) comprises a platform (104) that moves relative to a base (102) in response to a respective driving force supplied by a motor arrangement (106). An energy storage system (112) is electrically connected between the motor arrangement (106) and an electrical power input (120) configured to receive an external single-phase electrical power supply (122). The energy storage system (112) comprises battery management system (118) that controls a smart battery charger (116) to charge a battery arrangement (114) using electrical power received from the electrical power input (120) such that: i) under a first load condition, electrical power from the electrical power input (120) is used to supply the motor arrangement (106) and to charge the battery arrangement (114); and ii) under a second load condition, the battery arrangement (114) is at least partially discharged to supply stored electrical power to the motor arrangement (106).
