Abstract
Inertial force balance and ADAMS simulation of the oscillating sieve and return pan of a rice combine harvester
Highlights
During the cleaning process of a rice combine harvester, the oscillating sieve and return pan are influenced by the inertial force of rotary motion in addition to external loads
The main research on the inertial force balance includes the following: According to Chaudhary et al.[7], the shaking forces and shaking moments developed as a result of inertial forces in mechanisms were minimized using the genetic algorithm (GA), which was found to be better than the conventional optimization algorithm results
The analysis showed that: when φ=90°(the crank initial angle of the return pan was the same as the crank initial phase of the oscillating sieve), the degree of inertial force offset in the X direction was at a maximum and the overall inertia was at a minimum (Figure 23)
Summary
Return pan, the partial equilibrium method is more practical. The main research on the inertial force balance includes the following: According to Chaudhary et al.[7], the shaking forces and shaking moments developed as a result of inertial forces in mechanisms were minimized using the genetic algorithm (GA), which was found to be better than the conventional optimization algorithm results. Research on the inertial balance force on a combine harvester includes the following: Guarnieri et al.[9] noted that the imbalance between the reciprocating single-blade cutter bar and the slider-crank mechanism was due more to the periodic instability of motion and torque than to the alternative inertial force of the blade; the paper showed the existence of an optimum running speed that minimizes instability to understand the vibration characteristics of the knife-driving system. With respect to balancing an oscillating sieve, the research only optimized the inertial force equation or only adopted a simplified model of the slider-crank mechanism to simulate the oscillating sieve, resulting in a large error between the theoretical counterweight and practical counterweight. Based on a comprehensive consideration of the relative motion of the oscillating sieve and the return pan, the optimum mass for the overall balance of two devices was obtained, providing a design method for the counterweight that addresses the inertial force reduction of the oscillating sieve and return pan
