Transdisciplinary models of hydraulic drives of mobile machinery

Development of hybrid powered hydraulic construction machinery

a r t i c l e i n f o Facing the environment problems, the improvement on the efficiency of the construction machinery such as the excavator and wheel loader is highly demanded. The hybrid power systems used in automobiles have been adapted into the construction machinery. This paper first analyzes the difference between the hybrid powered automobile vehicle and the hybrid powered construction ...

Mathematical Modelling of a Hydraulic Accumulator for Hydraulic Hybrid Drives

the application of multivariate probit models for conditional claim-types (the case study of iranian car insurance industry)

هدف اصلی نرخ گذاری بیمه ای تعیین نرخ عادلانه و منطقی از دیدگاه بیمه گر و بیمه گذار است. تعین نرخ یکی از مهم ترین مسایلی است که شرکتهای بیمه با آن روبرو هستند، زیرا تعیین نرخ اصلی ترین عامل در رقابت بین شرکتها است. برای تعیین حق بیمه ابتدا می باید مقدار مورد انتظار ادعای خسارت برای هر قرارداد بیمه را برآورد کرد. روش عمومی مدل سازی خسارتهای عملیاتی در نظر گرفتن تواتر و شدت خسارتها می باشد. اگر شر...

Modeling and Analysis of Outrigger Reaction Forces of Hydraulic Mobile Crane (TECHNICAL NOTE)

This paper presents an original interactive analysis method consisting of mathematical calculation based on theoretical mechanics and mechanics of materials, and dynamics simulation for quantifying outrigger reaction forces of a kind of hydraulic mobile crane, aiming to avoid the eventualities during normal operation as far as possible, for example, tipping-over. First, a three dimensional dyna...
