Abstract:
To research the actual resistance for excavator in digging process, the relationship between manipulator motion, cylinder pressure and digging resistance was analyzed. On this basis, the equation for calculating digging resistance of excavator was proposed. By using tension sensor, a digging resistance test was done under the actual digging movement environment. And the obtained inclination angle and hydraulic cylinder signal data were imported into digging resistance calculation equation to get a calculation resistance. After comparing the calculation resistance with the tension sensor readings, the following conclusions can be derived: this calculation equation can reflect effectively the size and dynamic process of actual resistance during digging operation, and it can describe the instantaneous changes and impact status of real resistance much better can the empirical equation in which the resistance is directly proportional to the digging depth.
