A new method for increasing LDR in deep drawing is application of anti-lock braking system (ABS) on blank holder. In this method, instead of applying a constant force on blank and control the metal flow, the ABS system holds and releases the blank several times (20 to 50 times) which results increasing LDR. This study investigates the effect of different parameters of ABS on improving the condi...

A new dynamic friction force model for the longitudinal road/tire interaction for wheeled ground vehicles is validated via experiments with an actual passenger vehicle. Contrary to common static friction/slip maps, this new dynamic friction model is able to accurately capture the transient behavior of the friction force observed during transitions between braking and acceleration. A velocitydep...

We studied the strategies used by cursorial bipeds (ostriches) to maneuver during running. Eight ostriches were induced to run along a trackway and execute turns. Ground reaction forces and three-dimensional kinematics of the body and leg joints were simultaneously recorded, allowing calculation of joint angles and quasi-static net joint torques. Sidesteps, where the leg on the outside of the t...

OBJECTIVES To evaluate and compare long-term functional outcome after partial carpal arthrodesis and pancarpal arthrodesis in dogs using kinetic gait analysis. METHODS Fourteen dogs with 19 partial carpal or pancarpal arthrodeses were retrospectively examined and underwent force-plate gait analysis. Mean times since surgery were 29.4 and 24.4 months for pancarpal and partial carpal arthrodesi...

The variable combined brake system (VCBS) is a mechanism for motorcycles to simultaneously activate the front and rear systems by using one lever or pedal. purpose reduce risk of rollover accidents due misuse when panic braking. Due its ability in wide variation range braking force distribution (BFD) ratios between wheels, VCBS can achieve high effort driving comfort performances, provided that...

The dual-motor EV (Electric Vehicle) is increasingly favored by manufacturers for its excellent performance in terms of power and economy. How to further reduce energy consumption make full use the recovery an important support improve overall vehicle economy realize “dual carbon” strategy. For architecture, motor model, battery loss model longitudinal braking force are established recovery-dom...

Quadrupedal running on grades requires balancing of pitch moments about the center of mass (COM) while supplying sufficient impulse to maintain a steady uphill or downhill velocity. Here, trotting mechanics on a 15 deg grade were characterized by the distribution of impulse between the limbs and the angle of resultant impulse at each limb. Anterior-posterior manipulation of COM position has pre...

An antilock braking system (ABS) can ensure that the wheels are not locked during process which is an important to safety of braking. Regenerative also a crucial for hybrid vehicles and helps improve cruising range car. As such, coordinated control ABS research direction. This paper researches regenerative in vehicle based on composite structure motor (CSM-HEV). Firstly, two new modes engine-mo...

In this report, we present a methodology for assessing the benefits of different vehicle coordination strategies on the safety of a platoon during emergency braking. One can say that a coordinated braking strategy B is more beneficial than a strategy A, if strategy B leads to a larger reduction in the probability of a collision, the expected number of collisions, and the expected relative veloc...
