Field Measurement of the Motorcycle's Key Dimensions Using Simple Method and in-House Fabricated Instrument

Abstract

Out of many plausible causative factors for the spike in accidents, lack of riding skills is reported to be a significant reason for motorcycle mishaps. The riding skills can be improved through better availability of training facilities (simulator). Non-availability of the dimensional database (of different types of motorcycles), which are essential for simulator design, makes it difficult for the designers/ engineers to build the commercially available cheaper motorcycle-simulators. Moreover, the available measuring techniques and devices are costly and unable to satisfy motorcycle measurement's diverse requirements. Thus, the present research aimed to prepare the dimensional database of motorcycles using an in-house fabricated measuring instrument. Following the adaptive design method, the alpha prototype of a laser-pointer-based measuring instrument was developed. The calibrated device was used for measuring the dimensions associated with the handlebar, seat, and footrest of the 23 different motorcycles under study. Detailed (linear, angular, and circumferential) dimensions of the handlebar, seat, and footrest were measured using sliding calipers and protractors. Generated dimensional databases of 18 critical dimensions from the handlebar, seat, and footrest of the 23 different standard-motorcycles would be useful for deciding the motorcycle simulator's dimensions.

Exploring the association of riders’ physical attributes with comfortable riding posture and optimal riding position

“…After completing the session, the subjects were requested to leave the motorcycle test-rig and report the perceived discomfort and comfort (self-reported questionnaire) they experienced during the 5 min. This subjective rating assessment includes (1) Discomfort rating scale (as shown Appendix 35,40 The subjective rating scales are widely used in previous literature. [41][42][43] The present study adopted the procedure of using both comfort and discomfort scales (to evaluate the subject reliability) have also been proposed in many other studies.…”

“…21,29,34 The limits of adjustability in the test-rig for handgrip, footrest, and seat were decided based on a previous study and Japanese standard. 22,35 Figure 2 explains the specific dimensions (like width, length, etc.) of the seat, handlebar/grip, and footrest and the dimensional adjustability provided in the test-rig.…”

“…of the seat, handlebar/grip, and footrest and the dimensional adjustability provided in the test-rig. According to the survey (on 23 Indian standard motorcycles) by Arunachalam et al 35,36 the mean value of the seat dimensions (front width, narrowest width, the distance between the front width and narrowest width, and the widest length) and handlebar dimensions (handle grip length and handle grip width) were used in the test-rig. A flat (no curvature) seat (material: open-cell polyurethane; density: 82 kg/ mm 3 ) was used to control the effect of the seat on overall discomfort.…”

Risk of Musculoskeletal Disorder in the Working Posture of Online Motorcycle Drivers (Case Study: Drivers at Malang District)

“…Table 3, states that the role of the RULA score has an impact in determining severity information during driving. There were respondents 18,19,21,22,23,24,25,27,28,29 Inspections and changes need to be made immediately 6…”

“…The purpose of the follow-up examination is to provide advice on how to use the correct driving position with changes in posture according to the angle of the RULA and REBA integration study. Arunachalam et al provide a statement that to suppress musculoskeletal disorders requires replacement of work facilities [21,22]. Of course, changing the facility requires an in-depth ergonomics study to reduce the risk of both RULA and REBA.…”
