- Description
- 1.Which dummy spine is being loaded? Is it for one type of dummy or several dummies? For example, is there a need for the equipment to load H3 50th male, 5th female, etc? Answer: Just the HIII 50% at this time. Possibly to be use on the WIAMan once that ATD is manufactured. 2.What is the injury level as defined by APG - we understand that for a 50% male H3, it is about 6 kN? Answer: Yes. We are looking at the injury criteria in the Lumber Axial FZ direction at 0 ms duration is 1500 lbf. So 25% of that is 375 lbf. That is not a hard number so 375-400 lbf would be an acceptable level/range. I would also like to add that this is would be our target and normal operating range, but we would like to have the potential to do something that would be greater if possible. 3.Is the device required to deliver one cycle of loading to the lumbar spine? Or several cycles? If several how many and what is the allowed time lag between 2 loading cycles? Answer: 1 cycle 4.Is there a requirement on ramping rates for loading. For example, if it is desired to load the lumbar spine to 1.5 kN [abput 25% of 6kN - an accepted lumbar injury level], what is the desired loading rate as a function of time? Answer: I am not sure if I am going to answer this directly or not, but we would like to be able to load it as fast as possible. The idea is to simulate an under body blast, but at a much lower level. 5.Is the device to load the lumbar spine while it is attached to the dummy or is the lumbar spine detached from the dummy. We want it attached to the ATD. This would be a test done on a complete ATD. 6.What output is desired to be measured when the lumbar spine is loaded? We would like to measure the forces in the lumbar spine. This requirement is going to be captured by me. I would like some confirmation from their system what load was applied or what acceleration was applied. For example if the ATD is in a seat, have an accelerometer on the seat. 7.What is the intent of this device? Is it going to be used to test the long term stability of the lumbar spine and its durability? The intent is come up with a validation process for validating the lumbar spine. In a way yes, that is durability. Our must have is the ATD remain intact for this process. 8.How many duty cycles are needed per day from this equipment? I would say at most we would perform this test 20 times a day. 9.If the spine is attached to the dummy, are we required to design a restraining device for the dummy? Yes, would prefer the ATD to be in a seated position. 90-90-90 orientation. Would prefer to have a "throne" that is durable and does not deflect under impacts. A 5 point harness would be ideal. 10.Does APG need just a quote or a description of the proposed device? Both absolutely. Any type of diagram or figure would also be helpful to understand the device. The proposing offeror should come up with a pulse rate. The idea is to simulate an underbody blast event, but at a significantly lower level. The injury threshold the customer is referencing is the lumbar axial compression force in the FZ direction. The injury is 1500 lbf for 0 ms. 25% of that is 375 lbf. So somewhere between 375 and 400 lbf would be acceptable. The customer would like to add that this would be our target force, but would also like to have a system that could potentially deliver an impact greater than this. The controls for the system need to be provided by the successful contractor. As part of the control they need to be able to determine the level of pulse that they provided to the ATD. The data acquisition needs will be handled by the customer, who will measure what the ATD sees. The ATD is a HIII 50% male. Specifications can be found on the manufacturers website.
