When designing helical gears, the goal is to optimize gear weight, efficiency, and noise while simultaneously achieving required strength. In this study, macro geometry of a pair was optimized for low high noise; further, trends optimal solutions five combinations three objectives were analyzed. The mass efficiency directly used as design objectives. However, since calculation generally very complicated time-consuming, has not been objective, peak-to-peak static transmission error (PPSTE),...
Abstract Wind turbines are eco-friendly energy sources that generate electricity from wind power. Among their various components, gearboxes constitute the most critical loss owing to longest downtime. To guarantee durability, a flexible pin was designed based on original straddle-mounted for enhanced tooth load sharing and distribution in planetary gear set (PGS) of turbine gearbox (WTGB). The improved durability evaluated by calculating mesh factor face contact stress comparing these values...
In the design of wind turbine gearboxes, most important objective is to improve durability guarantee a service life more than 20 years. This work investigates how external loads caused by fluctuation influence both load distribution over gear tooth flank and planet sharing. A whole system model developed analyze gearbox (WTG) that consists planetary gearsets. Two models for different are employed quantify acting on input shaft WTG affect gears sharing among planets under quasi-static...
This paper presents a novel flocking strategy for large-scale swarm of robots that enables the to navigate autonomously in an environment populated with obstacles. Robot swarms are often required move toward goal while adapting changes environmental conditions many applications. Based on observation swimming behavior school tunas, we apply their unique patterns autonomous adaptation shape robot swarms. Specifically, each dynamically selects two neighboring within its sensing range and...
Despite the minimized puncture sizes and high efficiency, microneedle (MN) patches have not been used to inject hemostatic drugs into bleeding wounds because they easily destroy capillaries when a tissue is pierced. In this study, shelf-stable dissolving MN patch developed prevent rebleeding during an emergency treatment. A minimally site-selectively invasive drug delivery system established by using peripheral (p-MN) that does directly intrude wound site but enables topical absorption in...
This paper presents a laser scanner–based predictive safety system for excavators. Blind spots on excavators and operators’ carelessness cause majority of fatal accidents, such as those in which deaths occur due to collisions with objects construction site. A proper can enhance the vehicles sites. In this study, control algorithm collision avoidance was developed utilizing kinematics dynamic model based working area object behavior predictions. The behaviors were predicted by considering...
The purpose of the present study was to evaluate effect energy density on polymerization low-shrinkage composite resins.The number photons needs initiate process can be controlled by light intensity and curing time through form density.For study, two methacrylate-based (Premise [PR] Venus Diamond [VE]) one silorane-based (Filtek LS [LS]) resins were cured using a quartz-tungsten-halogen (QTH) light-curing unit (LCU) 473 nm diode-pumped solid state (DPSS) laser. Degree conversion (DC),...
