Principled Negotiation

2019-12-12
This highly interactive workshop focuses training on negotiation strategy and skills. This is not the manipulative, win-lose negotiation approach frequently taught today, where the winner eventually spends time and effort protecting his negotiated advantage against erosion, while the loser continually exploits loopholes and shortcuts to recover lost ground. Traditional negotiation is a wary dance based on mistrust, the true cost of which is lost in quality and brain fatigue - usually for someone other than the negotiator - over the life of the agreement.

2019-28-2559
The Automotive industry is in ever more need for a lesser weight car due to progressively stringent emission norms and the demand of customer to have better mileage. It can be a gargantuan challenge for automotive manufacturers to search for lesser weight material to meet both customers as well as regulatory norms. But in some cases such lower weight material can increase the cost and adding a expensive material which increases overall cost to a price sensitive market like India is not favorable. One such solution is using the indigenous plant fiber (Jute) in combination with propylene (PP) to make Interior plastics components. Jute a vegetable fiber also referred to as "the golden fiber" has high tensile strength, low extensibility and is well established in fabric, packing, agriculture, construction industries. The biodegradable Jute lesser weight & abundance (India is the leading manufacturer of the Jute) can be utilized in making automobile trim parts in India.

Performance Gains of Load Sensing Brake Force Distribution in Motorcycles

2019-11-21
2019-28-2426
Commercial motorcycles and scooters incorporate independent circuits for front and rear brake actuation, thus precluding load dependent brake force distribution. In all cases of manual brake force modulation between the front and rear wheels, there is poor compensation for the changes in wheel loads on the account of longitudinal weight transfer, thus making it is challenging to provide an adequate braking force to each wheel. The ratio in which the braking force should be distributed between the front and the rear wheels is dependent on the motorcycle geometry, weight distribution, mechanical sizing of braking system components, and is a variable based on the deceleration. This connotes that a fixed value of front and rear braking forces can be optimized for only a narrow range of motorcycle’s deceleration. Maximum braking performance occurs just prior to wheel lockup, as a sliding tire provides less grip than a rolling tire.

2019-28-0151
Abstract Drive train failures are most common in wind turbines. Lots of effort has been made to improve the reliability of the gearbox but the truth is that these efforts do not provide a life time solution. Majority of failures are caused by bearing and gearbox. It also states that wind turbine gearbox failure causes the highest downtime as repair has to be done at Original Equipment Manufacturer [OEM]. This work aims to predict the failures in planetary gearbox using fault diagnosis technique and machine learning algorithms. In the proposed method the failing parts of planetary gearbox are monitored with the help of accelerometer sensor mounted on the planetary gearbox casing which will record the vibrations. A prototype has been fabricated as a miniature of single stage planetary gearbox. The vibrations of healthy gearbox, sun defect, planet defect and ring defect under loaded conditions are obtained. The signals show the performance characteristics of gearbox condition.

Optimization of IP duct vane articulation for improved cabin airflow directivity

2019-10-11
2019-28-0132
CFD simulations are effectively used to cut down the vehicle development period and to completely understand the interaction between the cabin thermal comfort and mobile air-conditioning system. While the methodologies are well established to quantify the passenger thermal comfort behavior in a vehicle, the investigations to quantify the cabin airflow directivity still requires in depth understanding, even though a vast number of studies are available on cabin cool down performance. The air velocity achieved at driver and passenger aim point is one of the key parameter to evaluate the automotive air-conditioning performance. The design of duct, vent and vanes has a major contribution in the cabin air flow directivity. However, visual appearance of vent and vane receives higher priority in design because of market demand than their performance. More iterations are carried out to finalize the HVAC duct assembly until the target velocity is achieved.
