Abstract

An apparatus and device for repetitive use in automotive testing is provided. The apparatus includes a frame dimensioned in the same shape as a bicycle frame. The frame includes a first support beam and a plurality of second support beams. The apparatus further includes an elastic member elastically coupling each of the plurality of second support beams to the first support beam so as to allow the frame to separate when impacted and be easily reassembled for further testing. The device includes a disk having a first radar transparent layer opposite a second radar transparent layer and a reflective film disposed between the first radar transparent layer and the second radar transparent layer. The reflective film has a radar cross section pattern similar to that of an actual bicycle wheel when seen by automotive radar.

Claims

1. A testing apparatus for repetitive use in automotive testing, the apparatus comprising:

a carriage,

a frame mounted to the carriage, the carriage configured to move the frame, the frame having a first support beam and a plurality of second support beams coupled together so as to form a bicycle frame; and

a detachable coupling member coupling each of the plurality of second support beams to the first support beam so as to allow the frame to separate when impacted and be reassembled for further automotive testing.

2. The testing apparatus as set forth in claim 1, wherein the detachable coupling member is an elastic member.

3. The testing apparatus as set forth in claim 1, wherein the first support beam and each of the plurality of second support beams include a tube having a bore, the elastic member is a plurality of elastic members, a respective one of the plurality of elastic members disposed within a respective bore, wherein an end of each one of the respective plurality of elastic members is secured to the first support beam.

4. The testing apparatus as set forth in claim 3, wherein the first support beam and the second support beam have first layer and an intermediate layer disposed over the tube, the intermediate layer formed of a resilient material.

5. The testing apparatus as set forth in claim 4, wherein the tube is formed of a durable and rigid material, wherein the durable and rigid material is one of either a polycarbonate or garolite.

6. The testing apparatus as set forth in claim 4, wherein the resilient material is foam.

7. The testing apparatus as set forth in claim 4, wherein the first layer is made of a reflective material, and wherein the reflective material is one selected from the group consisting of:

steel, copper fabric, titanium, or aluminum.

8. The testing apparatus as set forth in claim 1, wherein the frame is removably mounted to the carriage.

9. The testing apparatus as set forth in claim 1, further including a wheel mounted to the frame, the wheel having a first radar transparent layer and a reflective film, the first radar transparent layer is disposed on the reflective film, the reflective film having a radar signature of an actual bicycle wheel.

10. The testing apparatus as set forth in claim 9, wherein the wheel further includes layer a second radar transparent layer opposite the first radar transparent layer, the reflective film disposed between the first radar transparent layer and the second radar transparent layer.

11. The testing apparatus as set forth in claim 9, wherein the reflective film includes a plurality of reflective strips extending radially from a center patch of the reflective film and an outer strip disposed on a circumferential edge of the reflective film.

12. The testing apparatus as set forth in claim 11, wherein the plurality of reflective strips is made of gold.

13. The testing apparatus as set forth in claim 11, wherein the reflective strips include an outer layer formed of gold, an intermediate layer formed of tin, and a bottom layer formed of copper.

14. The testing apparatus as set forth in claim 11, wherein each of the plurality of reflective strips is rectangular.

15. The testing apparatus as set forth in claim 11, wherein each of the plurality of reflective strips are trapezoidal wherein a proximal end of the strip is wider than a distal end of the strip.

16. The testing apparatus as set forth in claim 9, further including a pedal assembly having a pair of pedals.

17. The testing apparatus as set forth in claim 16, further including a drive configured to rotate the pedals.

18. The testing apparatus as set forth in claim 17, wherein the drive is mounted to a top portion of the first support beam.

19. The testing apparatus as set forth in claim 17, wherein the drive is mounted to a bottom portion of the first support beams.

20. The testing apparatus as set forth in claim 1, further including a wheel mounted to the frame, the wheel having a first radar transparent layer and a reflective film, the first radar transparent layer is disposed on the reflective film, the reflective film having a radar cross section of an actual bicycle wheel, wherein the wheel is rotatably mounted to the frame, the carriage including a slot configured to receive the wheel, a portion of the wheel disposed within the slot so as to allow the wheel to rotate as the carriage is being pulled.

21. A device configured to reflect a radar signal of an actual bicycle wheel, the device comprising:

a disk having a first radar transparent layer and a reflective film, the first radar transparent layer mounted on the reflective film, the reflective film includes a plurality of reflective strips extending radially from a center patch of the reflective film and an outer strip disposed on a circumferential edge of the reflective film, the reflective film having a radar signature of the actual bicycle wheel as seen by automotive radar.

22. The device as set forth in claim 21, further including a second radar transparent layer opposite the first radar transparent layer, the reflective film disposed between the first radar transparent layer and the second radar transparent layer.

23. The device as set forth in claim 21, wherein each of the plurality of reflective strips and the outer strip include an outer layer formed of gold, an intermediate layer formed of tin, and a bottom layer formed of copper.

24. The device as set forth in claim 21, wherein each of the plurality of reflective strips is rectangular.

25. The device as set forth in claim 21, wherein each of the plurality of reflective strips is trapezoidal wherein a proximal end of the strip is wider than a distal end of the strip.

26. The device as set forth in claim 21, wherein each of the plurality of reflective strips are equally spaced apart from each other.

27. The device as set forth in claim 21, wherein each of the plurality of reflective strips and the outer strip are made of gold.
