Academic literature on the topic 'Decelerometer'

There were carried out deceleration tests of category M1 vehicles using the BRAKETESTER model LWS-2/MC decelerometer on dry asphalt pavement t=(0±0,5) °C. The calculation method was considered and the coefficient of the vehicle deceleration variation taking into account technological progress was introduced.

The deceleration tests of M1 category vehicles were carried out using the BRAKE TESTER model LWS-2/MC decelerometer on dry asphalt concrete pavement at ambient temperature t = 17 ± 0,5 ºC. There were compared the values obtained as a result of measuring the adhesion coefficients of asphalt concrete pavement and those obtained during the brake tests.

The article describes the factors influencing the formation of braking parameters for two-wheeled vehicles, in particular, bicycles, moving on dry asphalt and ground. There were carried out braking tests to determine the deceleration using the decelerometer of LWS-2MC type on dry asphalt and ground. Depending on the braking system type, the method of braking, the mass of the two-wheeled vehicle and the weight of the cyclist, as well as the suspension design, there were built graphs, and regression equations were obtained. A quantitative assessment of the factors influencing the formation of a steady-state deceleration of a two-wheeled vehicle during emergency braking is given.

AbstractThe influence of the cargo weight loaded on the vehicle and the total gross mass of the vehicle on the braking characteristics is often researched from the road safety reason. However, there is not enough knowledge about the influence of weight and load distribution on the loading area of small trucks or vans on their braking characteristics. This article presents the results of measurements of braking decelerations of the van of N1 category and the braking characteristics of a vehicle loaded with different cargo mass with different cargo locations on the loading area. The impact of the longitudinal cargo position on the loading area on the load of the individual axles and thus on the braking deceleration of the vehicle was investigated. The influence of the height of the center of gravity on the dynamic axle load during braking was also determined. Method of direct vehicle deceleration measurement was used by a decelerometer. There were calculated cargo weight and cargo position influences on the dynamic axle load during braking according to the vehicle deceleration.

The presented diploma thesis deals with the measurement of car deceleration during engine braking from different starting speeds and different speed gears with a sample of vehicles. This piece of work consists of a theoretical part, where problem background is defined, selected driving parameters including the manner how to measure them are explained and the facts in the field of structural characteristics of the vehicle are given, further from a design of measurement methodology that gives an overall plan of implementation, all the respective information and a description of handling with decelerometer, further from a real measurement of the deceleration including an interpretation of partial obtained values and finally from the evaluation of all results with appropriate conclusions.
