Introduction: Due to the non-developed mechanization situation, chainsaw is a widely used tool in Iranian forests. This tool can trigger unwelcome disorders (e.g., white finger syndrome) due to the transmitted vibrations from its handle to the body members. Characterizing these vibrations can result in minimizing the intensity of these disorders. This study aims to investigate the effect of dif...

vibration generated by vehicles during road transport has an important impact on agricultural products' damage process, particularly in the case of fruits and vegetables. modulus of elasticity is one of the most conspicuous mechanical properties of fruits, the variation in which can be described as one of the most affecting damage criteria during transportation. this research was conducted...

manual citrus harvesting is commonly performing hard, expensive and time consuming. in this study, a factorial experiment with a completely randomized design in three replications was performed to find out the effect of frequency (three levels of 5, 7.5 and 10 hz), vibration time (three levels of 10, 15 and 20 seconds) on harvesting capacity and losses of thomson cultivar of orange. the results...

In the paper, an establishment of dynamic characteristics tabletops newly-developed optical tables is being discussed upon. Low-frequency vibration isolation systems are reviewed. Theoretical and experimental tests have been performed. Dynamic models table on a vibrating platform at different excitations developed, displacement resonance frequencies system established transmissibility curves pr...
