CATL Revolutionary Bedrock Chassis with Industry-Leading Safety Features. This chassis design has passed the toughest safety tests, including a 120 km/h frontal impact, with zero risk of fire, explosion, or thermal runaway. Its innovative design absorbs 85% of collision energy—compared to 60% in traditional chassis—ensuring maximum protection for passengers. Key features. 1) Cell-to-Chassis integration for optimized strength and energy efficiency. 2) Biomimetic tortoise-shell structure for indestructible battery protection. 3) Aircraft carrier-grade arresting structure to disperse impact forces and reduce injury risk. 4) Rapid high-voltage disconnection in 0.01 seconds after a crash. 5) With advanced materials like submarine-grade steel and aerospace aluminum, the Bedrock Chassis offers incredible rigidity and resilience. - Even after crash, due to airbags the passenger might be saved but the battery pack structural damage can lead to possible thermal runaway and explosion. For crash, battery pack impact absorbers are much needed for passenger safety as well. https://lnkd.in/grwTB_Az. https://lnkd.in/g2abmWn7 #EV #Safety #Innovation #CATL #BatteryTech #AutomotiveRevolution #Sustainability#CrashSimulation#VehicleSafety#CrashTest

💡Assembling a model of a V8 car engine🤯 A V8 engine has a total of eight cylinders, designed as two rows of four cylinders. V8 are common in trucks, large SUVs, and sports #cars. The V8 engine was first introduced by Cadillac in 1914 and became the standard for speed #power, smoothness, and performance in the #automotive industry. It was innovative #design featuring an alloy crankcase, a single iron casting for each cylinder block and head, side valves, a flat-plane crankshaft, and a displacement of 5.1 litres. This #design was not only powerful but also relatively lightweight, making it a popular choice for luxury and performance #vehicles. 📹 Craft Channel #innovation #technology #engineering #letsconnect #physics #v8 #engine

Assembling a model of a V8 car engine

Assembling a model of a V8 car engine is akin to embracing the heartbeat of automotive power and innovation. With its symphony of eight cylinders meticulously arranged in two rows of four, the V8 stands as an emblem of performance, grace, and precision engineering. Originating from Cadillac's pioneering vision in 1914, this engineering marvel swiftly became the gold standard for power, smoothness, and sheer performance in the automotive realm. Its revolutionary design, boasting an alloy crankcase and a single iron casting for each cylinder block and head, coupled with side valves and a flat-plane crankshaft, epitomizes the marriage of power and elegance. With a displacement of 5.1 liters, it commands the road with authority, yet remains remarkably lightweight, elevating it to the pinnacle of luxury and performance vehicles. Let the V8 engine inspire you to push boundaries, break barriers, and embrace the relentless pursuit of excellence. #V8 #EngineeringExcellence #Innovation #AutomotiveIcon 🚗✨

If you have been trying to pull apart and put together your v8 engine here’s a good practice on a smaller model!

Tesla cybertruck teardown - several differences from the conventional construction of vehicles, as expected. Battery is part of the structure (floor), several structural parts are cast instead of different formed and welded steel panels. Interesting. 4-wheels steering and drive by wire. Teardown is a great way to learn how things are made.

1) Multi-link suspension have multiple links and joints connecting the wheel hub to the chassis, creating redundancy in force paths. The indeterminacy ensures that forces are distributed across several components, reducing stress concentration on any single link. By being statically indeterminate, the system allows precise tuning of the suspension geometry (e.g., camber, caster, and toe angles), improving ride quality, cornering performance, and tire wear characteristics. 2) A statically indeterminate chassis is inherently more rigid, which helps distribute stresses caused by dynamic loads (e.g., bumps, braking, and acceleration) over the entire structure rather than concentrating them at a few points. Rigidity improves crashworthiness by ensuring energy absorption is distributed during impact. It also enhances handling by minimizing unwanted deformation during high-speed maneuvers. 3) Drive shafts and axle assemblies in rear- or all-wheel-drive vehicles. Axles are subject to bending, torsion, and dynamic loading during operation. A statically indeterminate analysis ensures these forces are properly distributed across supports and bearings, preventing localized failures. Indeterminate systems consider material flexibility and deformation compatibility, allowing engineers to design components that can endure real-world conditions (e.g., sudden torque spikes or uneven road surfaces) #mechanical #engineer #multilink #suspension #car #chassis #axle #shaft #transmission #application

Road vehicles vibrate at many frequencies depending on the road conditions the vehicle is driving in for vehicle such as bus the road vibration could reach (1-5HZ) ,if the natural frequency of the road vehicle is within that range a catastrophic phenomenon called resonance will occur so in order to make sure that the vehicle is safe an analysis called modal analysis must be conducted in early stages of the vehicle structure design stage, the video you see here is modal analysis of very simple bus structure model I use it for training and testing ,the first modal shape is or simply mode is at frequency of 6.8357HZ and it is torsional mode ,the second mode at frequency of 9.5682HZ bending mode, if the first dominant mode have frequency less than 5 HZ it means that changes in the design must be taken but the solution is not simply just increase the structure tubes thickness, to convince you the natural frequency in simple form is (natural frequency)=(stiffens/mass)^0.5 ,increasing the thickness will increase the mass and should decrease the frequency but in the other hand increasing the thickness will also increase the stiffens it is tricky ,for example the structure has mass of 1215.7kg and its first mode has frequency of 6.8357HZ ,if we increase the side and roof tubes to be 3mm instead of 2 mm the mass will be 1532.3kg and the first mode will be 6.8971HZ we increased the first frequency by less than 1% with 26% increase in mass ,the solution is to increase the stiffness in the direction of the vibration by introducing a new structure member, modal shapes is not deflections it does not have any physical meaning think about it as scale showing where is the most critical areas is. One last thing modal analysis could be used as check for modal contact in free-free modal analysis the first 6 natural frequencies (called rigid body mods) should be zero or numbers close to zero, three corresponding to three translation degrees of freedom and three corresponding to three rotational degrees of freedom if you have free or partially constrained part in assembly you will have non zero rigid body mods and the free part will appears moving away from the assembly.
