・Reduction of vibration of agricultural rubber crawler vehicles and identification of the optimal design parameters
Rubber crawlers are widely used as the driving system for farm and industrial machinery on account of their high mobility and traction on uneven terrain. A rubber crawler is composed of lugs, core bar, and some other materials. Due to the sectional form and the particular components of a rubber crawler, dynamic spring constant and the viscous damping coefficient vary periodically between the two lugs when the track rollers come into contact with the surface of the rubber crawler. Therefore, mechanical vibration of rubber crawler vehicles is larger than those on wheel-driven vehicles. In particular, it is necessary to reduce the amount of vibration when driving a rubber crawler on a road surface. Therefore, in this study, we have developed mechanical mode, which predicts vibration characteristics of agricultural rubber crawler vehicles the in order to construct analytical design principles.

Zhen Li, Zhongxiang Zhu, Jiahao Qin, Enrong Mao, Mitsuoka Muneshi, Eiji Inoue, Soyoung Shin, Factorial significance on tractor stability under variation of terrain roughness employing the Taguchi method, International Journal of Agricultural and Biological Engineering, 10.25165/ijabe.v11i5.3713, 11, 5, 88-94, 2018.09, Tractor rollover accidents remain an issue with the development of agricultural mechanization. Adopting the scale-model-based experimental approach, this study investigated the three most influential geometric factors of tractor in various agricultural ground conditions with improved configuration of force sensing system. The initiation of tractor rollover, associated with the tire-ground contact status, was investigated for various front tire types, ballast weights, and rear track widths. Employing the Taguchi method, the ground reaction forces applied to the tractor’s uphill wheels were measured and evaluated using stability indicators. By taking this approach, the effects and statistical significance of the three factors and their interactions were examined under various agricultural ground conditions. Results showed that the ballast weight significantly affected the ground contact status of the uphill front tire. The significance of the front tire type gradually increased as the road roughness increased, but dramatically decreased for an extremely rough road surface. Furthermore, none of the factors or interactions, except the factor of the rear track width for relatively rough roads, was statistically significant. The study revealed that not all commonly discussed factors consistently affect tractor stability. The results of the present study are thus expected to provide a reference explaining how to explore the necessity and feasibility of parameter adjustment before reconfiguring a tractor for higher stability..

Shuo Zhang, Zhen Li, Zhongxiang Zhu, Enrong Mao, Mitsuoka Muneshi, Eiji Inoue, Scale Model Experiment on Lateral Stability of Tractor Affected by Multi-factors, Nongye Jixie Xuebao/Transactions of the Chinese Society of Agricultural Machinery, 10.6041/j.issn.1000-1298.2017.10.046, 48, 10, 358-363, 2017.10, Along with the dramatically growing use of agricultural tractors, the associated vehicle lateral stability has been found to greatly affect operation efficiency and human safety. According to characteristics of the low speed driving condition of tractor on slope ground, a scaled experimental system for measuring the tire-ground reaction force was built. By applying the 3D printing technology, a scale-model-tractor attached with implement and the random terrain surfaces for the tractor to pass over was developed. Taking the uphill wheel load of the tractor as the main reference parameter, the lateral stability evaluation indexes for tractor's front and rear wheels were proposed. The choice of tire type, ballast weight, front and rear track widths, and implement height were selected as the control factors, while introducing the terrain roughness in classes E and F as the noise factors. Employing the Taguchi design of experiment, factorial significances were investigated by the corresponding ANOVA analysis. The experimental results showed that tractor frontal ballast had the greatest impact on the front-wheel-based tractor lateral stability, while the rear track width predominantly determined the rear-wheel-based one. Furthermore, an optimal tractor configuration was given by taking into account the stability indexes for both front and rear wheels. The approach provided a reference for tractor stability optimization design and a theoretical basis for further tractor anti-rollover control..

Jung Seob Choe, Kohei Takata, Eiji Inoue, Tae Wook Kim, Mitsuoka Muneshi, Takashi Okayasu, Hirai Yasumaru, Judging the abnormalities of agricultural machinery by using Mahalanobis' distance, Journal of the Faculty of Agriculture, Kyushu University, 62, 2, 469-476, 2017.09, This study calculated the Mahalanobis' distance, which is a multidimensional space distance with correlations, from the time-series data of 3-axis translational acceleration and 3-axis rotational angular speed, and examined whether this could be used in judging the abnormalities of the agricultural machineries. As the result, using the Mahalanobis' distance to determine the abnormality of the data was not possible for the changes in not-so-big behaviors, such as turning and temporary stop, but determining the abnormality of the data using the Mahalanobis' distance was clearly possible for sudden changes to the operating status of the equipment, such as a roll over and passing obstacles through an experiment using the model car. We hypothesized in the beginning that the distribution of the Mahalanobis' distance at the signal space could be separated with the distribution of the Mahalanobis' distance at the unit space. However, unless there is a large-scale change to the behavior, such as a roll over, etc., complete separation is difficult in reality, and we determined realistically that conducting the abnormality determination from the significant difference viewpoint by placing a threshold value to the normalized distribution of the Mahalanobis' distance at the unit space is possible..

Li Zhen, Mitsuoka Muneshi, Eiji Inoue, Takashi OKAYASU, Yasumaru Hirai, Zhu Zhongxiang, Parameter sensitivity for tractor lateral stability against Phase I overturn on random road surfaces, BIOSYSTEMS ENGINEERING, 10.1016/j.biosystemseng.2016.07.004, 150, 10-23, 2016.10, Statistics show that lateral overturns are the most frequent fatal accidents involving tractors. There is thus much research interest in improving tractor lateral stability. Previous research has discovered the effects of various factors on tractor dynamic responses. While these factors have been analysed separately, their relative significance with respect to other factors remain uncertain. Furthermore, the practical limits of what operators can do have not been considered. The present study assumed a possible case that a tractor operator has several spare tyres of different types and service condition. Additionally, the ballast weight, track width, and implement position can usually be controlled before operation. A scale model tractor was thus developed allowing changes to these factors. The model tractor was designated to pass over typical farming road surfaces. Moreover, the tractor lateral stability was evaluated in terms of the roll angle, lateral-load transfer ratio, and Phase I overturn index. Employing the Taguchi method, we arranged experiments and assessed the applicability of the three kinds of indexes regarding tractor Phase I overturn. Results revealed that the roll angle did not well reflect the initiations of overturns. Compared with the lateral-load transfer ratio, the Phase I overturn index had more convincing factorial effects on tractor stability. Further investigation of the suggested tractor configuration supported this conclusion by comparing predicted and experimental results. In practical cases, this approach may provide a reference for engineers to help operators improve driving safety with limited spare parts..
