A method of testing load and processing signal on wheel loader transmission

To acquire real loads of wheel loader transmission and to develop dynamics simulation and to analyze machine power for different user, a complete test program and a method of processing signal are proposed. In this article, the transmission torque of wheel loader are tested with the method of four sections per cycle in “V-type” routes. The original signals are filtered by low-passed filter and are eliminated anomalous spikes with the NSOFT. By comparing the effect of processed signal, acquires pure random load-time course. It concludes that one Hz of the low-pass filter frequency is suitable, and the test signal is in line with the actual work of Loader. It provides a effective method of load tested and signal processed on wheel loader transmission.
