Description

Description

A compact self-contained bench mounting apparatus designed to allow students at all academic levels to investigate basic and advanced principles of control including systems that are naturally oscillatory.

The CE109 Ball and Hoop Apparatus shows the use of electromechanical servo systems for position and velocity control. It also works as a model to show liquid slop problems, for example: aircraft missile fuel storage, fuel tankers and industrial pumping systems.

The apparatus has a steel ball that rolls inside a hoop. The hoop is free to rotate, but controlled by a servomotor. Transducers give outputs of the hoop and ball positions. When the hoop is under angular position control, the ball moves like a cylindrical pendulum. This allows students to use it as a model for the study of liquid slop dynamics.

Advanced studies cover:

The influence of liquid slop behaviour on vehicle control system design
The use of ‘pole zero’ in the analysis of control systems

TecQuipment recommends that you use the optional Tachometer (OT1) for experiments in calibration of hoop velocity. Also, if you are not using the optional software, then an Oscilloscope (OS1) will help to analyse the transient signals in some experiments.

Key features:

Self-contained and compact bench-mounting unit for basic control of position or speed, and advanced studies of liquid slop
Shows the problems of speed and position control of a mobile body or liquid in a container
Mimics industrial, aeronautical, fluid transport and pumping system problems with realistic results
All inputs and outputs buffered for connection to TecQuipment’s optional controllers or other suitable controllers
Front panel includes a mimic diagram of the process so that students can see what they are controlling

Learning outcomes:

The design and analysis of servo control systems for position and velocity control
The analysis and modelling of liquid slop dynamics
The use of ‘pole zero’ in the analysis of control systems

"AYVA has provided us with excellent support in getting training equipment that will enhance our chemical engineering labs. We have had the opportunity to work with their knowledgeable staff as well as representatives from TecQuipment and PIGNAT. We especially appreciated Sean McLaughlin, Technical Services Manager’s time and expertise when we purchased the H83 from TecQuipment. He was extremely responsive and resourceful during the on-site installation."

"Our mechanical engineering department recently wanted to upgrade our Gas Dynamics Laboratory in conjunction with our newly added aerospace program. After extensive research, we decided to purchase the AF27 Nozzle Flow Apparatus and the AF300 Intermittent Supersonic Wind Tunnel from TecQuipment with all the accessories including the VDAS Data Acquisition System. We are happy to report our investment has been well worth it. A perfect fit for our undergraduate laboratory. Students are raving how “cool” the units are and the relative ease to obtain accurate data. The laboratory size supersonic wind tunnel has been a big hit. At Mach 1.8, viewing the shock waves and expansion fans on an airfoil using the included Schlieren Apparatus has never been easier and more clear. The people at AYVA were amazing in helping us install the equipment. They answered all our question in a timely manner and delivered on time. The equipment is very well designed and built to last for a long time."

"I have worked with the AYVA team to upgrade my Mechanical Engineering lab. We have not only been provided with excellent pre-sale service but we also received valuable support after we placed our order. We were provided access to a number of resources which we were able to use to develop our own customized labs for the students. The structures equipment from TecQuipment is being used to teach student groups in several courses at the undergraduate level. There is minimal setup required and students are easily able to switch between experiments. The excellent quality of the TQ manuals has enabled us to design our labs with relative ease. The equipment was delivered on schedule and the AYVA team has been very diligent in following up and providing us with the resources we need in a timely fashion."

"In recent years, there has been a growing demand for engineering equipment in the undergraduate labs at the University of Guelph as we have expanded our program. AYVA has been proactive and assisted us diligently in addressing all our equipment needs. We now proudly showcase both PASCO and TecQuipment products in our teaching labs. The quality of the equipment and teaching material is exceptional. AYVA offers a broad range of equipment well suited to our various engineering disciplines and we look forward to exploring their extended product offering in the future."

"We have recently acquired six KUKA robots for our Controls and Robotics Lab at the University of Toronto. Not only we are very impressed with the quality and performance of the units, but we are also very pleased with the level of service and professionalism we encountered from AYVA. They have provided a continuous channel through which we could interface with KUKA and fulfill our technical demands from the time of procurement, through to installation, training of personnel and commissioning. It has been a textbook case on how to support laboratory work in higher education."

"Out of all the data acquisition systems I'm aware of, nothing approaches the convenience of the PASCO 850 interface. Between the broad range of available sensors and the simplicity of starting data acquisition, a wide range of tasks that would be incredibly complicated otherwise can be automated in minutes ... We have dedicated computers and 850 interfaces at each station in our labs so that data acquisition can be accomplished easily by our students whenever needed."

Gideon Humphrey

"I am a long-time user of TecQuipment products - in particular the Modular Structures Range as well as other Materials Testing equipment. I find the modules (over 10) very easy to set up and, more importantly, my students find them extremely easy to use as they move from station to station conducting a wide variety of measurements related to structures and materials. Each experiment can be completed in 30 to 45 minutes and I can accommodate several students working in groups of three. It is a great addition to both my Basic Structures and Hyperstatic Structures courses."

Dr. Gérard Poitras
University of Moncton

"I’m often running two lab sessions at one time in two different rooms. Being able to use the base module like TecQuipment's Hydraulic Bench and quickly be able to switch out the experimental modules makes running a tight schedule of laboratory sessions possible. With a few of my own modifications like adding quick connects and valves I can make this changeover even slicker. The AVYA experience is great! Their post-sale technical support is unparalleled."

Dean Milton,

"All of the students that have the opportunity to see the [Eridès] Refrigeration Trainer in operation and do their lab report based on readings really get a lot out of it. Interesting to note: Our refrigeration tech was fascinated by the unit. He is a very experienced technician, and he was simply amazed at seeing the thermodynamic cycle in action. Typically, refrigeration technicians follow pressure and temperature readings, and gauging from his reaction, they most times give little thought to the phase changes that take place inside the guts of the unit.'
