Mathematically Predicting the Performance Rate of Plow-Type Trenchless Machine

Abstract

This research was aimed to identify the main factors that influence the performance rate of plow-type trenchless machine and mathematically correlate these variables to predict performance rate. The mathematical analysis ended with an equation correlating the performance rate with the factors affecting it. The derived relationship was checked in various operational circumstances. The performance rate's practical experiments revealed that only for the 0.92 and 0.76 m disturbed soil depths, respectively, did the theoretical performance rate variation from the actual performance rate range from -3.0 to -0.7%. Also, for the 0.92 and 0.76 m disturbed soil depth, respectively, the field efficiency of plow type trenchless machine ranged from 49.7 to 45.4%. The novelty and innovativeness of this article is in the use of an analytical method to deduce a mathematical equation that can predict the performance rate; in determining the actual factors affecting the performance rate of plow type trenchless machine.
