This study aimed to design a bycatch reduction device (BRD) for shrimp beam trawl, which is manufactured by flexible materials to reduce bycatch for the gear in the South Sea of Korea. The model test was carried out to understand the shape of the gear in the water and to measure the variation of flow speed due to the BRD in a circulating water channel. Catches were compared between a shrimp b...
To solve the problem of low efficiency in digital generating machining for producing small or medium batches helical gears, a method to improve with an indexable disk milling cutter is presented this paper. First, mathematical model tooth profile and are established. Second, according spatial free-form envelope theory, overall planning scheme tool path given; relative position transformation ma...
In practice, the cost of a gearbox plays very important role in trade. Therefore, reducing gearboxes is an task not only when manufacturing but also designing them. order to reduce gearbox, there are many solutions which determining optimal partial gear ratios effective measure. This because it size, mass depends greatly on ratios. work presents method for calculating function two-stage helical...
