In cold rolling of thin strips, i.e., foils (Thickness
[ 2 ] - Static and Dynamic Analysis of Bus Structure and Chassis of O-457
With due attention to the fact that the local and foreign vehicle industries are changing and modifying the previous designs in order to produce new designs, the components of self-propelled are to be differently analyzed. Static and dynamic analysis is one of them. In this paper, chassis and body of a o-457 bus were studied and analyzed under finite element method (using ANSYS).This process wa...
[ 3 ] - Investigation of the Effectiveness of Using a CVT in Samand Automobile
This paper investigates the effectiveness of using CVT (Continuous Variable Transmission) in Samand automobile. For this analysis, the conventional Samand and a Samand equipted with CVT are modeled and simulated by using Simulink based software (ADVISOR) and the performances are compared. This analysis includes the effect of driving cycle, fuel consumption and the efficiency of components of ...
[ 4 ] - Performance Analysis of Different Modified MR Engines Mounts
Increasing current vehicle development trends for small, light, front wheel drive vehicles with low idle speeds have been forced automotive industries to use hydraulic engine mounts for further improvement in vibration, noise and harshness (NVH) performance of the vehicles. However, with the development of modern vehicle designs such as hybrid vehicles and variable engine management systems whi...
[ 5 ] - Optimal Roll Center Height of Front McPherson Suspension System for a Conceptual Class A Vehicle
In this paper, the effects of roll center height of McPherson suspension mechanism on dynamic behaviour of a vehicle are first studied, and then the optimum location of roll center of this suspension system is determined for a conceptual Class A vehicle. ADAMS/Car software was used for the analysis of vehicle dynamic behaviour in different positions of suspension roll center. Next, optimization...
[ 6 ] - Crash Test Simulation and Structure Improvement of IKCO 2624 Truck According to ECE-R29 Regulation
During the design and development of truck cabins, the safety of the driver and the front seat passenger in an accident is an important task and should be considered. The cab must be designed in such a way that in an accident a sufficient survival space is guaranteed. The aim of this study is to investigate the behavior of Iran Khodro (IKCO) 2624 truck subjected to a complex crash test accor...
[ 7 ] - Antilock Regenerative Braking System Design for a Hybrid Electric Vehicle
Hybrid electric vehicles employ a hydraulic braking system and a regenerative braking system together to provide enhanced braking performance and energy regeneration. In this paper an integrated braking system is proposed for an electric hybrid vehicle that include a hydraulic braking system and a regenerative braking system which is functionally connected to an electric traction motor. In the ...
[ 8 ] - کنترل فازی طول و مکان پنجره آینده نگری در رویکرد کنترل آینده نگر برای کاهش مصرف سوخت در حمل و نقل ریلی
کنترل آینده‌نگر رویکردی جدید در جهت کاهش مصرف‌سوخت در صنعت حمل و نقل جاده‌ای و ریلی می‌باشد. در این رویکرد با در نظر گرفتن شیب مسیر پیش‌رو، تغییرات سرعت توسط یک کنترل‌کننده فازی تصمیم‌گیری می‌شود به نحوی که اگر در مسیر پیش‌رو یک سربالایی باشد، قبل از رسیدن به آن به گونه‌ای سرعت افزایش می‌یابد که خودرو به راحتی از آن عبور کند و مصرف‌سوخت نیز کاهش یابد. در ساختار این الگوریتم قسمتی از مسیر پی...
[ 9 ] - تخمین سطح شارژِ مجموعه سلول لیتیومی با اتصال سری با استفاده از فیلتر کالمن تعمیم‌یافته
مجموعه باتری یکی از اجزای اصلی در خودروهای الکتریکی است که به‌طور معمول از مجموعه‌ای از سلولهای باتری تشکیل شده است که به صورت سری به یکدیگر متصل می‌شوند. یکی از مهمترین وظایف سیستم مدیریت باتری در خودروهای الکتریکی تخمین سطح شارژ مجموعه باتری است. سلولهای موجود در یک پک باتری بدلیل تلرانس‌های مختلف ساخت و شرایط مختلف عملکردی الزاماً سطح شارژ یکسانی ندارند و از این‌رو، سطح شارژ مجموعه باتری الزا...
