The leaf spring is the flexible component of dependent suspension, which has advantages of simple structure, convenient maintenance, low cost, and can be used to locate the axle. The traditional multi-leaf spring has various defects. The few-leaf-spring has been one of main development trend of leaf springs because of its excellent characteristics. In this paper, a few-leaf-spring with variable thickness...
Cushions, pallet and packing box made of honeycomb paperboard with different dimensions had been analyzed. Their mechanics capability and oriental structure had been gotten. The cushion models, had been built in 3D software, were in the same height but different number of layers. Their compressive performance had been tested in the FEA software. The stress maps of honeycomb cores subjected to even...
Experimental results in the field of forming processes have shown that forming loads are significantly reduced when applying vibrations to the die. Piezoelectric actuators are well suited for this purpose because large forces and small amplitudes of vibrations are typically required in such processes. The main objective of the models proposed in this study is to describe the dynamical behavior of...
