This paper presents a full-car model of vehicle fitted with roll resistant specific HIS system in order to research the coordination of the main modals of sprung mass. Based on the transfer matrix method and state space method, the mechanical and hydraulic coupled multi-body dynamic equation is derived. The eigenvalue and eigenvector is solved by eigenvalue iteration identification method of frequency-dependent characteristic. By discussing the characteristic of the damping components which are the dominant parameters of the coupled system, an innovative design approach of damping components of the HIS system is proposed. Finally, comparison of vehicle vibration is carried out between vehicle with traditional suspension and that fitted with roll resistant specific HIS system. The obtained result indicates that with the proposed design approach of damping components, the roll resistant specific HIS system can promote the capacity of anti-rollover specific observably with reasonable comfort performance.

The concrete pump truck integrates transportation with pouring process ，which is characterized with flexibility, facility and celerity in civil engineering. As for the concrete pump truck, the arm system is the most important because the rationality of the arm directly influences the performance and pouring position of the truck in its application in civil engineering. For the arm system of the concrete pump truck, the movement of the arm system and the hydraulic cylinder are analyzed respectively with multi-body dynamic theory. By using numerical arithmetic to resolve the dynamic equation, the terminal track of the arms is analyzed. It shows that the kinetic equation built by multi-body dynamics can describe the dynamic characteristics of pump truck exactly.

AbstractNowadays, the world is shifting towards a more sustainable way of life, and product designers have an important part in this change. They have to eco(re)design their products to make them environmentally conscious throughout their lifecycle, and especially at their end-of-life (EoL). However, one can observe that synergy between product designers and recycling-chains stakeholders is lacking, mainly due to their weak communication. While many design-for-EoL approaches coexist in the literature, design from EoL must also be taken into account to fully develop a circular economy.RE-CYCLING is an innovative design approach that supports both design for and from EoL. This paper focuses on the recycling EoL-option and the validation of the associated indicators. To validate the design-for-recycling indicators, the recyclability of three smartphones is assessed. It is expected that indicators provide a similar score as none of them was designed to be recycled; results comply with expectations. In parallel, the convenience of using recycled materials in smartphones is analysed to validate our design-from-recycling indicators. It is found that the proposed indicators can indeed support designers integrating recycled materials in products.

In order to conveniently analyze the dynamic performance of tracked vehicles, mathematic models are established based on the actual structure of vehicles and terrain mechanics when they are moving on the soft random terrain. A discrete method is adopted to solve the coupled equations to calculate the acceleration of the vehicle’s mass center and tractive force of driving sprocket. Computation results output by the model presented in this paper are compared with results given by the model, which has the same parameters, built in the multi-body dynamic software. It shows that the steady state calculation results are basically consistent, while the model presented in this paper is more convenient to be used in the optimization of structure parameters of tracked vehicles.
