| Abstract: | A single-cylinder engine is widely used in motorcycles and garden machines and so on.Its vibration is a main influence factor for the performances of the machines.The kinematical and dynamic behaviors of an eccentric slide block balancing mechanism are analyzed here.The relation between design parameters and inertial forces and inertial moments induced by imbalances is deduced.Its design rule is put forward.The results are applied to the engine of a garden machine and the correctness of the analysis and the design is proved. |
