Abstract:

The derivative of acceleration with respect to time is used to evaluate and ensure driving comfort during acceleration and deceleration. Frequent and rapid changes in acceleration means frequent and rapid deformation, which can lead to the destruction of the load. The article proposes to minimize the amount of acceleration due to the rational choice of transmission ratios in intermediate gears and the law of changing the engine torque. The use of continuously variable transmissions allows you to solve the problem by choosing a rational law for changing the gear ratio of the transmission. The m

Abstract:

The paper analyzes research on improving the energy efficiency of cars with two independent motor-transmission systems by matching the transmission parameters and engine operating modes. When using two identical powertrains, each driving the wheels of one side of the car, there is no problem of equalizing efficiency, since both engines operate in the same mode. There is also no problem with determining the part of the mass driven to the crankshaft of one engine, since the driven mass is divided in half between both engines. The problem arises when two engines are installed on a car with their

A flying car can fulfill two functions, as a vehicle on the road and as an airplane that capable of flying. To reduce aerodynamic drag, the drive wheels must be able to fold so that a flexible transmission system is required. The Hydrostatic Transmission (HT) system is a flexible transmission that uses a hose to connect hydraulic pump, which is coupled to the engine, to hydraulic motor, which is coupled to the wheel. This research analyzes the specifications of hydrostatic transmission components to optimally transmit power from a V6 engine to two drive wheels through a speed gear transmission

Abstract:

Virtual and laboratory-based design techniques can accelerate the development process over conventional prototype-and-field-test procedures. In car acoustics, the transmission of outside airborne noise into the cabin needs to be understood and managed. Here, we evaluate the accuracy of sound field recording and reproduction techniques for investigating the transmission of airborne noise into the driver's cabin of a car. Reference measurements of a real sound field, generated by a truck with idling engine to create a realistic scenario, were carried out in a semi-anechoic chamber. The reference

Introduction. The issues of ensuring optimal fuel consumption modes are the subject of constant research in the field of vehicle operation. Works in the field of reducing fuel consumption in most cases are devoted to the study of the design of power units, transmission or aerodynamic features of the body of cars. At the same time, the issues of determining the optimal laws of control of unsteady movement from the point of view of the synthesis of algorithms for controlling the movement of a car have not been considered. To optimize the transmission ratio of cars with unsteady movement, the aut

Abstract. Floating Car Data (FCD) are one important data source in traffic telematic systems. The original variable in these systems is the vehicle velocity. The paper analyses the measured value “vehicle velocity" by methods of information technology. Consequences for processing, transmission and storage of FCD under condition of limited resources are discussed. Starting point of the investigation is the analysis of spectral characteristics of velocity-time-profiles. The spectra are determined by the Discrete Fourier Transform (DFT) from measurement data and simulation data of a microscopic t

The current coronavirus outbreak, attributable to SARS-CoV-2, has triggered widespread interest in the risk of infection associated with confined spaces. This study focuses on establishing a model for simulating the spread of COVID-19 within a car cabin due to a driver’s cough using computational fluid dynamics (CFD) simulation in the ANSYS Fluent software. Previous studies have mainly focused on the transmission of the virus over large areas; however, attention has shifted to confined areas, including cars. This study fills this gap by modelling the flow regions, velocity, and pressure fields
