Options for Defining Flexible Tire Motion EDEM’s Built-in Kinematics, Force, and Torque Controllers Pros: Easiest to set up and fastest to…
As the electrification of transportation and energy systems accelerates, the battery pack has become one of the most critical components in modern engineering. While battery cells themselves often receive most of the attention, the enclosure that houses and protects these cells plays an equally vital role. It must maintain…
Electrode Roller Pressing is a key manufacturing step in battery electrode production, used to achieve the desired thickness, density, and surface uniformity of the coated electrode sheets. In this process, the coated electrode—typically aluminum foil for the cathode or copper foil for the anode—is passed through a pair of…
In battery manufacturing, aluminum foil is widely used as the current collector for the cathode due to its excellent electrical conductivity, corrosion resistance, and low density. During the electrode fabrication process, large sheets of coated aluminum foil are precisely cut into the required shapes through a process…
Contact modeling is a critical component of multibody dynamics simulations, especially in applications involving latch mechanisms, robotics, electric tools, and similar mechanical systems. Accurate and efficient contact handling significantly impacts the realism and stability of the simulation. Overview In multibody…
