eature Article Wheel Slip Simulation for Dynamic Road Load Simulation FFeatureApplication Article Application ReprintofReadoutNo.38 Wheel Slip Simulation for Dynamic Road Load Simulation Increasingly stringent fuel economy standards are forcing automobile Bryce Johnson manufacturers to search for efficiency gains in every part of the drive train from engine to road surface. Safety mechanisms such as stability control and anti-lock braking are becoming more sophisticated. At the same time drivers are demanding higher performance from their vehicles. Hybrid transmissions and batteries are appearing in more vehicles. These issues are forcing the automobile manufacturers to require more from their test stands. The test stand must now simulate not just simple vehicle loads such as inertia and windage, but the test stand must also simulate driveline dynamic loads. In the past, dynamic loads could be simulated quite well using Service Load Replication (SLR*1). However, non-deterministic events such as the transmission shifting or application of torque vectoring from an on board computer made SLR unusable for the test. The only way to properly simulate driveline dynamic loads for non- deterministic events is to provide a wheel-tire-road model simulation in addition to vehicle simulation. The HORIBA wheel slip simulation implemented in the SPARC power train controller provides this wheel-tire-road model simulation. *1: Service‌ load replication is a frequency domain transfer function calculation with iterative convergence to a solution. SLR uses field collected, time history format data. Introduction frequency. The frequency will typically manifest itself between 5 and 10 Hz for cars and light trucks. (see To understand why tire-wheel simulation is required, we should first understand the type of driveline dynamics that need to be reproduced on the test stand.

Inertial Dynamometer for Shell Eco-Marathon Engine: Validation
ICEUBI2019 International Congress on Engineering — Engineering for Evolution Volume 2020 Conference Paper Inertial Dynamometer for Shell Eco-marathon Engine: Validation Daniel Filipe da Silva Cardoso, João Manuel Figueira Neves Amaro, and Paulo Manuel Oliveira Fael Universidade da Beira Interior Abstract This paper aims to validate the construction of an inertia dynamometer. These types of dynamometers allow easy characterization of internal combustion engines. To validate the dynamometer, tests were carried out with the same engine (Honda GX 160) installed in the UBIAN car and kart, which after calculating the inertia and measuring engine acceleration in each test performed, allows to create the torque characteristic curve from the engine.

AUTODYN SERIES AUTODYN SERIES CHASSIS DYNAMOMETERS HAND HELD CONTROLLER EDDY CURRENT ABSORBERS VERSATILE Simple and accessible control To simulate real-world driving With upgradeable options and while testing conditions wheel base adjustment We Make It Better 1.262.252.4301 | www.powertestdyno.com | [email protected] | Sussex, WI, USA FEATURES THAT MATTER Push-Button Wheel Base Adjustment Push-button wheel base adjustment is not only convenient; it’s also the right way to accommodate AWD vehicles because it allows the vehicles to be loaded in the same position on the rolls every time. Non-adjustable cradle rolls systems that simply stack rolls together to accommodate AWD vehicles produce inconsistencies in testing as one vehicle might land between rolls and another may land on top of the rolls, creating a different testing environment for each vehicle. Trunnion Mounted Differentials Precision, trunnion mounted differentials allow individual torque measurement of each axle (AWD models) so you can see total torque through the RPM range and also the torque split between the front and rear axles to tune for drivability. They also allow accurate measurement of dyno losses so the inertia of the dyno does not affect the test results. Further, it means SuperFlow® dynos are not susceptible to inaccuracies based on heat in the dyno components like the differentials and couplings. 2 Eddy Current Absorption High capacity eddy current absorbers allow for both inertia and loaded testing. On all models, they’re coupled to each other and to the rolls with positive mechanical couplings like differentials and driveshafts. This allows accurate measurement of parasitic horsepower losses in each individual dyno we manufacture.

Measuring the Performance Characteristics of a Motorcycle
August 2019, Vol. 19, No. 4 MANUFACTURING TECHNOLOGY ISSN 1213–2489 Measuring the Performance Characteristics of a Motorcycle Adam Hamberger, Milan Daňa Regional Technological Institute, University of West Bohemia – Faculty of Mechanical Engineering, Univerzitní 8, Pilsen 306 14, Czech Republic. E-mail: [email protected] This work deals with an experiment, whose output is the comparison of power characteristics which were meas- ured in three ways. The first way used a commercially manufactured dynamometer. For the second measurement, a special dynamometer with our own computing system and a sensor within this project was created. The last way of measuring the performance characteristics was done without a dynamometer. The measurement works on the principle of acceleration the spinning of a flywheel. Due to this, the measuring is called an acceleration test. The basic principles are described before the experiment in order to grasp the characteristics. All explanations are based on schemes and easy mathematical and differential formulas to describe the construction of the dynamom- eter and the principle of its functions from the engine to the computer. The relations between published and un- published quantities defining engine dynamics are explained here. In the end, this work points to possible and intended measuring failures which are an infamous practice at many measuring stations. Keywords: Dynamometer, power characteristics, driving forces, torque, performance. Introduction These forces are divided into two basic sorts. The first one is dependent on velocity and it can be written as: All vehicle engines overcome resistances on the road. 2 Fres( v )= c21 v + c v + ( c val + sin( )) m g [ N ], (1) where: φ … climb angle [rad], v … velocity [m/s], m … full weight[kg], 2 c1,c2,croll … coefficients [-], g … gravity acceleration [m/s ].

Use of Engine Performance Testing As a Laboratory Experiment
Session 2756 USE OF ENGINE PERFORMANCE TESTING AS A LABORATORY EXPERIMENT Emin Yılmaz Department of Technology University of Maryland Eastern Shore Princess Anne, MD 21853 (410)651-6470 E-mail: [email protected] Abstract The goal of the “ETME 499-Independent Research in Mechanical Engineering Technology” course is to introduce students to designing, manufacturing, upgrading, repairing and testing mechanical systems. The goal of laboratory part of “EDTE 341-Power and Transportation” course is to service small and/or large internal combustion engines. The purpose of this project was to service the gasoline engine, the engine dynamometer attached to it, and carry out some engine performance tests. If successful, the engine performance testing will be incorporated into the “EDTE 341-Power and Transportation course” or the “ETME 301-Thermodynamics and Heat Power” course as one or more laboratory experiments. EDTE 341 and ETME 301 are technical elective and required courses, respectively, for Mechanical Engineering Technology (MET) students. The gasoline engine was disassembled and serviced as a requirement for the laboratory part of the EDTE 341 course. Servicing of the engine-dynamometer system was completed as an ETME 499 project. Instrumentation for the fuel consumption measurements were added and the measurements were carried out. The results indicate that, at constant load, as the engine speed was increased the fuel consumption increased. The same trend was seen at constant speed; the fuel consumption increased as the load was increased. Simulated fuel economy (miles/gal) graph indicate that the engine economy was about flat at higher loads, but, was decreasing slightly at low loads when the engine speed was increased beyond about 1500 rpm.
