In spite of the fact that flexibility crankshaft diesel engines exhibits notable nonlinearities, analytical modeling such nonlinearities is not yet realized. The present study thus analytically models effect eccentricity on flexible and piston secondary motion. modeled as summation hydrodynamic dynamic mass crankshaft. also absolute value vibrational displacement center paper proves sensitive t...

Sorghum seedling transplanting is an essential agricultural activity in Sub-Saharan Africa. However, conventional manual of sorghum a time-consuming, labour-intensive, costly with low rate, uneven plant distribution, and degree accuracy. In order to realize rapid precise seedlings transplanting, duckbill-type mechanism has been designed. This five-bar linkage consisting two crankshafts, connect...

The purpose of this study was to solve the problem that damping rubber or silicone oil torsional dampers used in crankshafts is not adjustable and cannot effectively control vibration at different resonant frequencies. Based on controlled rheological properties magnetorheological (MR) smart materials, designed a new type variable MR damper (MRTD) proposed semi-active method crankshaft under mul...
