Chuan, Tran Quoc, Phuong, Nguyen Kim, Ha, Nguyen Thi Hai, Ngoc, Vu Minh, Tu, Tran Ngoc
The paper presents a results of study the full-scale self-propulsion
characteristic for series cargo ship 12500DWT built in Vietnam based on the
unsteady RANSE method with Body Force Propeller method. Two case studies were
analyzed: propeller open-water, and...
Design and Durability Test of the Main Assemblies of Active Anti-roll bar - Trang 385-394 - 2023
Ngoc, Nguyen Anh, Hoa, Tran Phuc, Quan, Vu Hai, Tien, Nguyen Minh, Bang, Kieu Huu
The anti-roll bar has the effect of increasing the stable motion of the vehicle.
It has the role of receiving, transmitting force and torque between the wheel
and the chassis, reducing the vibration frequency of the car, ensuring the
smoothness and stick on the road...
Integral Action Finite Set Model Predictive Current Control for Brushless DC Motor - Trang 271-285 - 2022
Thai, Lam Cuong Quoc, Duong, Van Tu, Nguyen, Huy Hung, Nguyen, Tan Tien
This paper presents an integral action finite set model predictive control
(I-FCS-MPC) to apply BLDC motor control. One of the advantages of this method is
it allows the current timeslot to be optimized about energy (current or
voltage), which will be expressed...
A Parametric Study on Product Quality During Forward-Reverse Extrusion Process - Trang 83-89 - 2023
Thi, Thu Nguyen, Nguyen, Minh-Quan, Minh, Nguyen Thi Hong
Forward-reverse extrusion is a common method in the manufacture of transmission
components that require high strength and rigidity. This is a method that helps
the metal to deform in two directions: forward and reverse directions compared
to the punch movement....
Experimental Study of Premixed Laminar Combustion Characteristics of Gasoline/Air Mixtures in Constant Volume Vessel - 2024
Tong, Duy Quoc, Nguyen, Minh Tien, Nguyen, Le Chau Thanh, Pham, Minh Man, Do, Phu Nguu, Phung, Minh Tung, Bui, Van Hung, Ho, Tran Ngoc Anh
This work measures the laminar combustion characteristics of gasoline-air
mixtures at different equivalence ratios (ϕ = 0.8, 0.9, 1.0, 1.1 and 1.2) using
the pressure rise method combined with a constant volume combustion chamber. The
pressure rise...
