Book Description
More and more vehicles are being electrified. Mobile working machines and heavy trucks are not excluded, and these machines are often hydraulically intense. Electrification entails new requirements for the hydraulic system and its components, and these requirements must be taken into consideration. Hydraulic systems have looked similar for a long time, but now there is an opportunity to advance. Many things change when a diesel engine is replaced with an electric motor. For example, variable-speed control becomes more relevant, electric regeneration becomes possible, and the use of multiple prime movers becomes an attractive alternative. The noise from the hydraulic system will also be more noticeable when the diesel engine is gone. Furthermore, the introduction of batteries to the system makes the energy more valuable, since batteries are heavy and costly compared to a diesel tank. Therefore, it is commercially viable to invest in the hydraulic system. This thesis revolves around the heart of the hydraulic system, that also is the root of all evil. That is the pump. Traditionally, a pump has had either a fixed displacement or a continuously variable displacement. Here, the focus is on something in between, namely a pump with discrete displacement. The idea of discrete displacement is far from unique, but has not been investigated in detail in combination with variable speed before. In this thesis, a novel design for a quiet pump with discrete displacement is presented and analysed. The results show that discrete displacement is relevant from an energy perspective for machines working extensively at high pressure levels and with low flow rates, and that a few discrete values are enough to make a significant difference. However, for other cycles, the possible energy gains are very limited, but the discrete displacement can be a valuable feature if downsizing the electric machine is of interest.

Book Description
The subject of the first volume is the issues related to the components and systems of transport machines. Motor vehicle systems tests are described: suspension dampers, steering, brakes and differentials. Design issues of machine elements operating in extreme conditions are also addressed. The possibility of increasing wear resistance in high-speed and ethanol-powered engines is analyzed. An extensive part covers the dynamics of hydraulic, electro-hydraulic and mechanical-hydraulic systems and the issues of diagnostics and automatic control in such systems. Aspects of the regional system of motor transport, public transport and transport and logistics of agricultural machinery are also addressed. The volume also examines selected technical and economic issues of gas transport. Topics on modelling of production processes with the transport of products are a complement.

Book Description
This book combines the topics of Root Cause Analysis (RCA) and Lubrication Degradation Mechanisms (LDM) with the goal of allowing the reader to develop the disciplined thought process for getting to the root causes of each of the degradation mechanisms. This new way of thinking can be applied to other areas within their facility to mitigate or eliminate any future recurrence. Lubrication Degradation: Getting into the Root Causes strives to break down the complex topic of Lubrication Degradation into its six most common failure mechanisms. It presents the mechanisms as manageable components and then teaches the reader how to identify the typical root causes associated with each failure mechanism. The main aim of this book is to get the audience to look past the physical root causes and really unearth the underlying human and/or systemic roots to prevent recurrence of these types of failures. The book offers a field-proven and practical root cause analysis approach. An ideal practical book for industry professionals involved with Plant Operations, Engineering, Management, Maintenance, Reliability, Quality, and also useful for Technicians.

Book Description
Mobile Working Machines are defined by three characteristics. These machines have a cer-tain task of doing a working process, they are mobile, and they have a signifi cant energy share in their working functions. The machines should be as productive, efficient and of high quality as possible. All these machines in the fi eld of agriculture, forestry, construction, logistics, municipal sector, and in other special applications work in different applications. But, many technologies placed in the machines are the same, similar or comparable; therefore, different branches can learn from each other. Mobile Working Machines provides a wide and deep view into the technologies used in these machines. Appropriate for new engineers as well as those who wish to increase their knowledge in this field, this book brings together all the latest research and development into one place.
