Dynamic modeling of disc brake contact phenomena [PDF]

open access: yesFME Transactions, 2011
An interaction between a brake disc and friction material of automotive brake is characterized by a number of braking phenomena. These phenomena are influenced by brake operation conditions (applied pressure, speed, and brake interface temperature) and ...

Brake Torque Sensor Calibration Device

open access: yesApplied Sciences
This paper deals with the design of a calibration device for measuring the residual torque of the vehicle brake. It informs about the problems and purpose of the brakes, requirements placed on the brake system, and the design of vehicle brake systems. The practical part of the research contains the design of four versions of the calibration device and ...

Jumping in simulated lunar gravity with blood flow restriction as a potential exercise countermeasure: The acute physiological effects

open access: yesExperimental Physiology, EarlyView.
Abstract The present study examined the cardiovascular, metabolic, neuromuscular and perceptual effects of low‐intensity jumping in simulated lunar gravity (∼20% bodyweight) with blood flow restriction (BFR). Fourteen healthy adults (24 ± 4 years; 1.81 ± 0.06 m; 75 ± 12 kg) completed an incremental jumping test in simulated lunar gravity (9.5° head‐up ...

A comparison of the neuromuscular, cardiopulmonary and muscle oxygenation responses to single‐ and double‐leg cycling in older adults

open access: yesExperimental Physiology, EarlyView.
Abstract Previous work in younger adults has shown that during small muscle mass exercise, the tolerable degree of neuromuscular impairment at task failure is greater than during large muscle mass exercise. However, no study has compared the neuromuscular responses to small and large muscle mass exercise whilst matching exercise modality in older ...

Braking Scheme for Vector-Controlled Induction Motor Drives Equipped With Diode Rectifier Without Braking Resistor [PDF]

open access: yes, 2006
This paper deals with sensorless vector control of PWM-inverter-fed induction motor drives equipped with a three-phase diode rectifier. An electronically controlled braking resistor across the dc link is not used.

Sprint‐interval training with post‐exercise blood flow restriction increases mitochondrial content and respiration

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The mechanisms underpinning improved maximal oxygen uptake following sprint interval training (SIT) with post‐exercise blood flow restriction (BFR), compared to SIT alone, remain unclear. This study examined the effects of 6 week SIT with (BFR; n = 12) or without (CON; n = 8) post‐exercise BFR on V̇O2peak${{\dot{V}}_{{{{\mathrm{O}

Five Weeks of Sprint Interval Training Increase Absolute Power Output Within Severe‐Intensity Domain Without Altering Muscle Activation or Fatigability

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 7, July 2026.
ABSTRACT The study aimed to investigate whether a 5‐week sprint interval training (SIT) could improve neuromuscular function (NMF), alter electromyographic activity (EMG), and attenuate fatigability, ultimately resulting in improved cycling performance during constant work rate (CWR) exercise within the severe‐intensity domain.

Research on permanent magnet reduction gear for trams

open access: yes机车电传动, 2022
As a ground transportation, the tram needs frequent speed regulation. Relying on mechanical braking when decelerating will cause excessive wear of the mechanical devices.
