New Proposal and Design to Add Retarders in AutomotiveBy Esmaeil Mirmahdi, Mohammad Janat, Alireza Darkeh, Mahdi Nikbakht
Abstract: Today, the issue of occupant safety is one of the most important issues in the automotive industry. Oneof the most important factors in improving the braking performance of cars has been considered in thearticle is the use of auxiliary brakes. Among the common auxiliary brakes that were proposed in carsand used by experimental test, we can mention retarder brakes. Used in heavy vehicles in passengercars will also be widely used …

Sensitivity of Bearings to Vibration: Its Effect on Ultrasonic Waves, Its Effect on Bearing LifeBy Esmaeil Mirmahdi, Hossein Karami, Omid Khosravi, Mohammad Hajsadeghi
Abstract: High vibrations caused by various factors in the bearing of a car is a common problem in the automotive industry. Nowadays, the issue of reducing excess vibrations that cause bearing failure in industry has been considered by engineers and industry owners. By examining these vibrations and controlling the vibrations in the cars, it will increase the bearing life and reduce the number of out-of-program stops. The experiments were performed using …

Experimental Investigation of Bearing Inner and Outer Wall Defects by Ultrasonic WavesBy Esmaeil Mirmahdi, Mohammad Yavari, Mohammad Reza Fayazi, Milad Bakhshayesh
Abstract: Sometimes the bearings show their defects by exchanging between the network gears, and this can be useful for experimental and similar experiments. These defects will cause the bearing to malfunction, the bearing to malfunction and need to be repaired and maintained, which can be useful for the industry and save potential costs. These defects can be significant through ultrasound to combine time and frequency variables, which is addressed in this …

Experimental Test Results on the Effect of Ultrasonic Waves on Defects in Car Bearings: The Effect of Defect SizeBy Esmaeil Mirmahdi, Reza Zalaghi, Mohammad Reza Johari, Amin Molaei
Abstract: To check for defects in car bearings, they are identified and measured by sound waves that are affected by the defect. Based on sound, it is called ultrasound technology because it uses high frequencies. High frequencies are the basis of ultrasound. Two features are useful for low-speed cars, which by definition usually have poor signal tolerance. High frequencies are sensitive to the effects of sound waves. In addition, the ultrasound …
