dc.description.abstractWhole-body-vibration is the transmittance of vibration from a workplace machine or vehicle to a person’s body. To know the effect of subsoiling on vibration it needs documentation which helps to decide safe exposure limits in sense of duration of safe subsoilling hours. In this study, three types of subsoilers as single tine straight shank subsoiler (S1), double tine straight shank subsoiler (S2), and double tine curved shank subsoiler (S3) were used. The subsoilers were operated at three different depths (20-25, 25-30, and 30-35 cm) and effect of subsoiling on different parameters as vibration, fuel consumption, wheel slip, draft, and soil disturbance area were observed and analysed. The vibration was increased as operating depth was increased. It was recorded maximum at depth of 30-35 cm (d3) for “X” direction as 0.296 m/s2, for “Y” direction as 0.284 m/s2, for “Z” direction as 0.431 m/s2, and for total acceleration (Ahv) as 0.451 m/s2. The vibration in “X” direction was increased 5.86 % and 11.64 %., in “Y” direction was increased 6.52 % and 12.42 %., in “Z” direction was increased 3.68 % and 8.11 %., and total acceleration (Ahv) was increased 10.23 % and 13.59 %, for d2 and d3 depths compared to d1 depth. The r.m.s. acceleration was found minimum with single tine straight shank subsoiler (S1) as 0.234 m/s2 in “X” direction, as 0.221 m/s2 in “Y” direction, as 0.332 m/s2 in “Z” direction, and as 0.362 m/s2 of total acceleration. On the other hand, the fuel consumption, wheel slip, and draft were found maximum for S2 subsoiler and minimum for S1 subsoiler. Soil disturbance area was observed maximum for S2 subsoiler and minimum for S1 subsoiler. Also same effect as vibration, the increased subsoiling depth resulted increased in these parameters. The safe exposure working hours were calculated as work with S1 subsoiler at the depths of d1, d2, and d3 were 8 h, 6 h, and 6 h respectively. Same as for S2 subsoiler were 4 hours at all depths and for S3 subsoiler it was calculated 4 to 6 hours. Summarisingly, looking to the results obtained, it is resolved that- The performance of single tine straight shank subsoiler with particular reference to total whole-body-vibration transmitted to the operator was found as 0.362 m/s2. Also, the working performance of single tine straight shank subsoiler with reference to fuel consumption and specific fuel consumption (2.89 l/h & 43.72 g/h/bhp), wheel slip (10.81 %) and draft (1266 kgf) were also comparatively less than double tine straight shank subsoiler and double tine curved shank subsoiler. Therefore, single tine subsoiler can be a better option for subsoiling. Only the soil disturbance area and field capacity becomes half as compared to double tine subsoilers.en_US
