| Abstract | Many researches have been conducted to test the tractive performance of cage wheels at higher slip values. Past studies have shown that the maximum performance occurs around 15% slip. The curve of slip against the tractive performance drops down after 15% slip. This study was aimed to find out the performance of cage wheels at slips below 25%. Study was conducted at 44% (db) soil moisture content in silty clay loam soil, having liquid limit of 38% and plastic limit of 20%. This study focused on the tractive performance of two types of cage wheels namely normal and perfect chevron lug cage wheels with slip varying from 5% to 25%. The set up included test wheel frame (cage wheel frame) and carriage frame which maintained the constant speed. To study the effect on sinkage, a set up for loading was fabricated. This time, slip was kept constant and maintained at 15% slip and for corresponding loads, the sinkage was measured and the forces were recorded. Loads considered were 10 kg, 20 kg, and 30 kg. Each loading was encompassed with three sinkage levels. It was easier to operate the cage wheel at lowest speed to acquire the lowest slip value. Performance of the cage wheels was compared with respect to slip, sinkage and loads. Each test was replicated thrice. At slip values between 10% and 15%, the perfect chevron lug wheel produced higher drawbar power and its tractive efficiency was higher than the normal cage wh |
