Body In White

To reduce noise and make the structure of the car more rational, we established modal test system of car's body-in-white in this paper. Car body-in-white was mounted on rigid platform with four coil springs. The car was excited by an electromagnetic exciter. The method of single-point excitation and multi-point collecting vibration was used in this test. Excitation point was chosen in the bearing beam. Signals picked up by the acceleration sensors were processed in the software of Mescope. With this system, different modal frequencies and modal characteristics of the car are acquired. The results show that modal parameters are effective and reliable and those parameters can be basis for the designer to improve the structure of the car.

This paper reports on an investigation into the proposed usability of virtual reality for a manufacturing application such as the assembly of a number of component parts into a final product. Before the assembly task itself is considered, the investigation explores the use of VR for the training of human assembly operators and compares the findings to conventionally adopted techniques for parts assembly. The investigation highlighted several limitations of using VR technology. Most significant was the lack of haptic feedback provided by current input devices for virtual environments. To address this, an instrumented object (IO) was employed that enabled the user to pick up and manipulate the IO as the representation of a component from a product to be assembled. The reported findings indicate that object manipulation times are superior when IOs are employed as the interaction device, and that IO devices could therefore be adopted in VEs to provide haptic feedback for diverse applications and, in particular, for assembly task planning.

Disorder Risk

The purpose of this study was to quantify how musculoskeletal disorder exposure risk changes in an auto assembly task as a function of car body rotation. Twelve subjects participated in the study. There were three car body angles including 1) zero or standard, 2) forty-five degrees and 3) ninety degrees from horizontal. Musculoskeletal exposure included spine loads, spine posture, shoulder posture, neck posture and wrist posture, as well as normalized electromyography of the shoulder and neck. The results showed that musculoskeletal disorder exposure risk decreased as the car was rotated to forty-five degrees and further decreased as the car was rotated to ninety degrees. Thus, rotating the car body reduces musculoskeletal exposure which in turn may reduce the risk of musculoskeletal disorders. It should be noted that the results may vary with other assembly tasks.
