Design and Manufacturing of a Simulator of Engine and Road for Performance and Strength Testing of Power Transmission Elements
, M.Sc. Thesis Sharif University of Technology ; Durali, Mohammad (Supervisor)
Abstract
The object of this project was the design and manufacturing of a machine to simulate engine and road loading in testing the performance of automotive gearbox and other power transmission elements. The prototype was made with a 1 to 50 scale compared to a full size car. Two AC machines with servo control action simulate the engine power curve and road loadings on the car respectively. The controller parameters of AC machines can be changed through a user friendly HMI to enable the system to simulate different engines and roads. The machine can be used to evaluate manual as well as automatic transmission gearboxes. A test log delivers the test data at the end of each test. Attempts were...

, Article Aviation ; Volume 21, Issue 4 , 2017 , Pages 132-142 ; 16487788 (ISSN) ; Rezazadeh Mohamadi, M ; Dolatkhah Takloo, S ; Mardani, M ; Sharif University of Technology
Abstract
Due to the wide usage of rotary equipment and the necessity of their testing for maintenance and repair, test rigs have become necessary. The mechanical closed-loop test rig developed in Sharif University of Technology branch of ACECR (Academic Centre of Education, Culture and Research) is a test rig with low energy losses that is suitable for testing high power gearboxes such as aerospace or wind turbine gearboxes. It can be loaded up to 489Hp at a maximum speed of 3000 rpm, and the test components can be tested in different testing conditions including a variety of torques and speeds. This paper describes the preliminary, conceptual, and detailed design, steps including frame work design,...
