Measurement and optimization of nonlinear damping systems for agricultural engineering vehicle cab
The issue of nonlinear dampness in the cab of agricultural engineering vehicles is examined by analyzing the vibration reduction system of a specific agricultural loader. Firstly, the specific loader was tested under different conditions. Then, the nonlinear vibration reduction system model of the cab–seat–human body is established by using the measured frame vibration signal as input. Finally, the multi–objective genetic algorithm is used to optimize the root mean square (RMS) value of vertical acceleration of the cab and seat. The test results show that the seat vibration is significantly greater than the acceleration of the cab floor under driving and working conditions, so the seat vibration is amplified and the seat parameter setting is unreasonable; the engine and the working device are also an important part of the cab vibration source, in addition to the uneven road surface. Comparing the RMS values of the vertical acceleration of the cab and seat, which were calculated by the model and obtained from the vehicle test, the error does not exceed 6%, indicating that the model’s accuracy meets the requirement. The vehicle experiment proves that the RMS value of the vertical acceleration of the cab and seat is reduced by 16% and 53%, respectively, after optimization. This study provides a theoretical basis for the design of the damping system for the cab of agricultural engineering vehicles.

Agricultural engineering and feeding the future
\"Agricultural engineers are in the front line in the challenge to provide a secure food supply for our world. This timely book explores how engineers design methods, as well as machinery for growing and harvesting crops, to make farming more efficient. Real-life examples help students understand key concepts related to this important profession. With an overview of the engineering design process, readers are encouraged to apply the same steps into their own agricultural engineering challenge.\"-- Provided by publisher.

Agro-technology : a philosophical introduction
\"Humans have been modifying plants and animals for millennia. The dawn of molecular genetics, however, has kindled intense public scrutiny and controversy. Crops, and the food products which include them, have dominated molecular modification in agriculture. Organisations have made unsubstantiated claims and scare mongering is common. In this textbook Paul Thompson presents a clear account of the significant issues--identifying harms and benefits, analysing and managing risk--which lie beneath the cacophony of public controversy. His comprehensive analysis looks especially at genetically modified organisms, and includes an explanation of the scientific background, an analysis of ideological objections, a discussion of legal and ethical concerns, a suggested alternative--organic agriculture--and an examination of the controversy's impact on sub-Saharan African countries. His book will be of interest to students and other readers in philosophy, biology, biotechnology, and public policy\"-- Provided by publisher.

Engineering Agriculture at Texas A&M
The abundance of agricultural production enjoyed in the United States is the result of a federal-state partnership that relies on land grant universities to respond to the needs of society through research, invention, problem-solving, outreach, and applied science and engineering. The Biological and Agricultural Engineering Department at Texas A&M University, established in 1915, has been an important part of that effort. Over the hundred years of its existence, it has successfully tackled the challenges of mechanization, electrification, irrigation, harvest, transport, and more to the benefit of agriculture in Texas, the United States, and the world. In this book, historian Henry Dethloff and current department chair Stephen Searcy explore the history of the department-its people, its activity, its growth-and project the department's future for its second century, when its primary task will be to sustainably help meet the needs of a predicted 9.6 billion Earth residents and to recognize that societal food concerns are focused more and more on sustainable production and human health.

Construction and Practice of the Practical Education System for Agricultural Hydraulic Engineering in the Context of Emerging Engineering Education
Under the background of “Emerging Engineering Education”, promoting reform in the practical teaching of Agricultural Hydraulic Engineering is a crucial task for cultivating water conservancy professionals with sustainability competencies in the new era. This study addresses current issues in the practical education of Agricultural Hydraulic Engineering, including fragmented practical content, disjointed tiered training, superficial teaching models, and simplified assessment methods. Guided by the Outcome-Based Education (OBE) concept and incorporating sustainability education principles, and integrating the distinctive features and course orientation of the university’s programme, this study implements a multidimensional practical teaching reform characterized by “three level–four integration–five dimension–three objective” framework in Agricultural Hydraulic Engineering. This reform has achieved significant outcomes: teaching quality has been notably enhanced, with students demonstrating substantially improved practical and innovative capabilities, earning over ten national and provincial competition awards in the past two years. Faculty teaching research capabilities have strengthened, resulting in multiple provincial-level teaching reform projects and top-tier course approvals. The proportion of courses achieving a satisfactory level of target attainment stands at 66.7% of the total practical courses. Graduate and employer satisfaction rates reached 96.2% and 100%, respectively. The results demonstrate the strong applicability and effectiveness of this multidimensional practical teaching model in fostering talent equipped for sustainable water conservancy development, providing an important reference for practical teaching reforms in agricultural universities during the new era.

The effect of tine, wing, operating depth and speed on the draft requirement of subsoil tillage tines
In this study, the effect of tine type, adding wing, operating depth and forward speed on the draft requirement of subsoil tillage tines was investigated in clay loam soil. Three subsoil tillage tines (subsoiler, bentleg and paraplow), four levels of forward speed (1.8, 2.3, 2.9 and 3.5 km/h), three levels of depth (30, 40 and 50 cm) and winged and no-wing tines were examined with the exception of bentleg as it would not be winged. It was revealed that draft of the tines is less affected by forward speed but is much affected by tine type, depth and wing. It was observed that an increase of speed and depth plus adding wing results in an increase of draft in all tines. Additionally, it was found that in all depths and speeds, subsoiler required more draft than paraplow and paraplow required more draft than bentleg. Multiple regression models including the studied parameters were developed to predict the draft requirements for each tine with high accuracy.
