• Why not use servo hydraulics actuation like the others? 

    In-fact all the other manufactures producing full car dynamic test rigs for motorsports use servo-hydraulic systems. They have been producing basically the same system for over 20 years. Throughout the years the control valving systems have gotten slowly better. They have gone beyond the "Bang Bang" valving systems that have been in use for so long. However the level of control and precision is and will continue to be way behind our much more modern and advanced systems. Producing a capable dynamics test system outside hydraulics requires one to utilize the very latest in electromechanical and electromagnetic systems. With this well engineered and fully developed system you have testing capability that is much more precise, easier to use, less expensive to produce and much more environmentally responsible, all this while costing less than 50% as much to operate. We believe developing our latest systems without providing our customers the very latest in technology, superior function and the lower in operation cost would be irresponsible. It is important to us for our customers to know that we provide the latest in proven technology to provide them superior test solutions.

  • How can Geo Systems Discovery diagnose so many different areas of kinematics, compliance and dynamic movements. It seems other systems focus on one or two areas. Do the GEO Systems test platforms give up something to gain the versatility? 

    It is true that 7 posters focus exclusively on dynamics testing in vertical motion and K & C systems focus on kinematics and compliance issues. Also it is true that the Geo Systems "Discovery" is the only system that provides crucial data in the areas of kinematics, compliance and dynamics. The architecture of the Geo systems discovery is unique. It is the only system designed from ground up as a motorsports test system. It is not a OEM test rig modified to work in the motorsports realm as are the others available. In design we responded to what motorsports teams needed most, this was time. Developing a system that allows so many conditions to be analyzed in one vehicle set up was the closest we could possibly come to providing them time in a box. Testing that would typically take 2 days or more can be accomplished in often half the time. There is no penalty for this.

  • You indicate elsewhere in your promotional materials that utilizing the GEO Systems test platforms was in some way more environmentally responsible than some of the other systems being used in motorsports. How can that possibly be the case? 

    That point was made in comparing the dynamic operations of the GEO Systems test platforms with the commonly used servo hydraulic 7 poster test systems. To operate the hydraulic systems requires a large hydraulic power unit, these units contain approx. 300 gallons of hydraulic oil in a single test system. Depending on the system and its use this oil is replaced approx. every 1-3 years. Consumption could be higher with any malfunctioning valves, fitting or hoses of which there are many. The Geo systems use no hydraulic oils, no consumable fluids of any type. Compare this to a 10 year operational time of a servo-hydraulic system that may utilize in excess of 800 gallons of hydraulic oil that most be disposed of. Multiply that by the number of hydraulic based test systems in use and its a disturbing situation if you are concerned about the environment. Our systems also consume less than a 3rd of the electrical energy of a servo hydraulic test system, again extending that savings in resources over a large number of units in use.

  • With the GEO Systems being built differently using different technology than the established manufactureres why should someone be comfortable with your components being sure we won't be stuck in a situation that we can't get your parts? 

    That concern is understandable. The components were very carefully chosen so they are not specific to our use. We have chosen Mitsubishi as our data and control system partner the largest supplier of these high technology systems in the world. Further these major components are inventoried by Mitsubishi in almost every major country in the world. So in fact the parts are much more readily available than offered by any other test system manufacturer in the world.

  • You mentioned prices associated with the test platforms but not about installation or excavation and costs associated with the under floor materials and labor. What should be budgeted for installation? 

    We did not mention these costs due to the fact they are completely unnecessary. The GEO Systems test platforms mount to the floor surface. Depending upon the functionality of the system they may require an isolation pad system, a very minor cost in the scheme of things. Installation and training of these systems is typically completed in 2-5 days dependent upon machine functionality.

  • As capable as the GEO Systems test platforms are their complexity causes some concerns regarding dependability, reliability and the level of maintenance that maybe required. How much maintenance is required to keep them working properly? 

    The GEO Systems test platforms are very capable test platforms that is certainly true However the extensive functionality and superior precision in no way translates to high maintenance. The drives, bearings and data systems are used around the world in high technology industrial applications in many cases in settings requiring 24/7 operation We have never experienced a failure with one our electromechanical systems. They are inherently less maintenance intensive and more reliable than servo hydraulic systems. Our systems have the capability to be diagnosed by us in a remote situations anywhere in the world.

  • Why an 8 post design and not 7 post like the others? 

    8 post design is not favorable for servo-hydraulics. There is potential for a servo -hydraulic actuator to jump position, or lose position independent of each other. This can be caused by a servo valve malfunctioning resulting in a loss of control, undershoot (not reaching commanded position), overshoot (not stopping at position), and ow inconsistencies. When 3 servo-hydraulics are used, they are positioned in a way where they can pivot on the opposite axis when position is lost. Four actuators can do several thousand more coordinated attitudes than 3 actuators can. In order to achieve this, special electronic actuators are utilized. These electronic actuators are mechanical with absolute encoding. There is no way for actuators to jump or loose position from one another. The coordinated control is an algorithmic sequence that places each actuator at the correct position at the correct time. There is also a precision attitude plate with high quality spherical ball joints. The attitude plate connection points of the ball joints have precision load cells. The attitude plate restricts any possibility of damage to the vehicle, and the load cells monitor the actuator loads to insure absolute coordinated motion is achieved.

  • Do the GEO Systems Test Platforms require advanced test engineers to run test scenarios and interpret data or can an experienced race mechanic or set up man be able to do it? 

    The GEO Systems is much easier to operate than a typical servo hydraulic 7 post system. Every test mode has a single test screen that is very intuitive and user friendly. There is also a limits screen where the operator or engineer can establish safety limits for displacements, force, or test functions allowed? It is always good practice to have an operator who has been involved in vehicle set up, and has rst hand knowledge of the vehicles being tested. The GEO System is congured to do preliminary discovery of the vehicle to establish constraints against over traveling or overloading the vehicle. The operators typically understand the real time logged data after a few sessions. In most cases there is an engineer working with the operator. The engineer typically evaluates the test data and dictates changes needed for that vehicle. It is not necessary for an engineer to be present during testing. An experienced operator can construct a test plan, perform the testing required, and provide the data les for others to evaluate at a later time.

  • How does the kinematics and compliance capabilities compare to a traditional K & C Rig? 

    If you are referring to a machine such as an AB Dynamics K & C system it compares very favorably. The GEO Systems Discovery produces more test routines while generating better quality data. It is quite difficult to make changes while a car is on a AB Dynamics rig. With a GEO Systems Discovery you can make more changes much faster and easier than can be accomplished on other test systems. This allows more data to be collected in a similar time.

  • With the additional capability of the GEO Systems Discovery how much more does it cost than the K & C and 7 Post Dynamic test systems? 

    With all the comparisons we have done comparing costs of a K & C machine to the GEO Systems Discovery the Discovery was approx. 40-50% less expensive! You would need to compare your required functionality to get more specfic answers. But our system will cost MUCH less while providing more capability. The situation is similar to a servo-hydraulic 7 post system. Comparing installed systems the GEO Systems Discovery will be approx. 40-50% less expensive! The Discovery will provide approx 10 times the amount of testing scenarios.
