Current global markets are volatile, where companies are striving to deliver greater quality, more customization, faster response, more innovative designs and lower prices. New models need to be introduced in the market more frequently, which has given momentum for designing family of products. Development of family of Products using a platform approach requires making decisions regarding platform selection and trade-off studies, which require analysis and evaluation of performance for the entire family instead of an individual products. One of the first steps in performing these activities require development of solid models for the entire family quickly and automatically as platform and family member configurations and size are changed. This paper presents an approach to automatically generate CAD models for a family of products. In the approach, a product family template that integrates configuration and parametric design information is presented. The template is implemented in the developed Product Family CAD (PF-CAD) module for Pro/E. A coffeemaker product family is used as a case study to automatically generate solid models of product family members from customer input.

Fea Analysis

Designing family of products require analysis and evaluation of performance for the entire product family. In the past, products were mainly mass-produced hence the use of CAD/CAE was restricted to developing and analyzing individual products. Since the products offered using a platform approach include a variety of products built upon a common platform, CAD/CAE tools need to be explored further to assist in customization of products according to the customer needs. In this paper we investigate the development of a Product Family FEA (PFFEA) module that can support FEA analysis of user customized product families members. Customer specifications for family members are gathered using the internet, users are allowed to scale and change configurations of products. These specifications are then used to automatically generate 3D solid models of the product and then perform FEA to determine feasibility of the customer specified product. In this paper, development of the PFFEA module is illustrated using a family of lawn trimmer and edger. The PFFEA module uses Pro/E to generate the solid model and ANSYS as the base FEA software.

<p><span>The objective of this paper is to propose a modified Single Ended Primary Inductance converter topology with passive lossless snubber cell to achieve Zero Voltage Switching (ZVS) of the device near turn off and Zero Current Switching (ZCS) near turn on. By using the snubber cell effectively with the converter reduces the switching stress by restricting the large variations in voltage and current. The detailed analysis of the circuit with relevant waveforms of the circuit is described. The circuit is designed for a load of 100W at 12V output from an input source ranging between 20-30V. The circuit is modelled in MATLAB Simulink platform and the parameters are compared with conventional circuit. From the results it is shown that the proposed circuit operates at a lesser voltage stress and at higher efficiency than conventional one.</span></p>

Abstract. Owing to the different approaches for remote tower operation, a standardized set of indicators is needed to evaluate the technical implementations at a task performance level. One of the most influential factors for air traffic control is weather. This article describes the influence of weather metrics on remote tower operations and how to validate them against each other. Weather metrics are essential to the evaluation of different remote controller working positions. Therefore, weather metrics were identified as part of a validation at the Erfurt-Weimar Airport. Air traffic control officers observed weather events at the tower control working position and the remote control working position. The eight participating air traffic control officers answered time-synchronized questionnaires at both workplaces. The questionnaires addressed operationally relevant weather events in the aerodrome. The validation experiment targeted the air traffic control officer’s ability to categorize and judge the same weather event at different workplaces. The results show the potential of standardized indicators for the evaluation of performance and the importance of weather metrics in relation to other evaluation metrics.
