2022 Maha Workshop - Effective learning of fluid power technology

The 2022 Maha Workshop is a half-day fluid power workshop that will start at 8:30 a.m. on May 17th at Purdue University. To register for the workshop, go to the Maha Conference registration site. The workshop has a $200 participation fee. The first 15 participants who register for both the Maha Conference and the Maha Workshop will receive a $100 discount.

Topic A: Metering control technologies and demonstration

This topic covers the fundamental concepts of metering control in hydraulic control systems. The features of meter-in and meter-out hydraulic control are illustrated. The meter-in control concept is further expanded to the technologies of load sensing and open center control which are commonly used in mobile hydraulics.

The topic includes a theoretical lecture followed by a hands-on experience on newer hydraulic trainers.

Theoretical aspects:

Meter-in control: basic circuit, flow vs pressure characteristics, system behavior in case of overrunning loads
Meter-out control: basic circuit, flow vs pressure characteristics, pressure amplification aspect, system behavior in case of overrunning loads
Advanced meter-in control: load sensing circuit, single function & multiple functions
Advanced meter-in control: open center circuit, single function & multiple functions

Hydraulic trainers:

Each trainer will host a group of max four individuals. A handout will be provided to build and test the circuits described above.
Each circuit will be built by using the proper components through quick-couplers.
For each circuit, the basic characteristics of the system will be demonstrated through the use of proper sensors (pressure and flow sensors) and by acting to proper hydraulic control valves.

Topic B: Uses of Augment Reality (AR) for fluid power training

This topic will focus on providing an overview of the essential software and hardware tools necessary to develop modules for fluid power training for applications in sales, component and system development or traditional onboarding. The workshop presents the fundamental concepts for the creation of virtual elements and tools that can be used to augment the learning experience.

Learning objectives:

The participants will learn about various tools that are available for the development of AR scenes using online and open-source content.
The participants will learn to identify the differences, advantages, and challenges for, Virtual Reality (VR), Augmented Reality (AR) and Mixed Reality (MR).
The participants will interact with predeveloped AR scenes and will experience and operate two fluid power components using Mixed reality googles and a laptop or tablet computer.
The participants will explore and learn how to superimpose virtual objects on real scenes using mobile devices to augment a traditional training experience.
