【Abstract】 The excavating resistance is a major pa-rameter for excavator design. In this paper anexperimental study of excavating resistance using regressive orthogonal design is introducedand the main factors affecting excavating re-sistance and their calculation formula obtain-ed. New investigation for new research methodon it is also performed.更多还原
