Paper Title: The Influence of Vacuum Booster Design Parameters on Brake Pedal Feel Key words: brake pedal feel; bench test; vacuum booster parameter; forward design Research and/or Engineering Questions/Objective As one of the most important characteristics of the brake system, brake pedal feel is determined by the structural and kinetic parameters of the components of the brake system. With the improvement of consumer demands for braking reliability and comfort, brake pedal feel caught the attention of the manufacturers. Vacuum booster is the servo power component of the brake system, whose parameters have a direct influence on the brake pedal feel characteristics. This study could contribute to the guide of vacuum booster forward design and brake pedal feel characteristics prediction. Methodology A dynamic model of the complete brake system which has a full mathematical description and contains the structure parameters is established in the Matlab/Simulink software, considering the input velocity characteristics.

Abstract The brake system and components are essential active safety systems for users of motor vehicles, one common NVH phenomenon known as Brake Disc Thermal Coning creates a perception of poor braking system performance. Although Brake Disc Thermal Coning does not deteriorate the braking distance or the vehicle performance, is a concern for the customer who identifies any undesired vibration as a potential performance loss resulting in complaints and warranty claims. In order to increase the quality, and reliability of the products, Automotive OEMs have created processes and tests, today incorporating the ones based in computational solutions, to identify, prevent and correct potential issues before its present in the final product. As computer technologies like Computer Aided Design (CAD), Computer Aided Engineering (CAE) and Computer Aided Manufacturing (CAM) have become more robust, and PC power clusters have increased the complexity of the problems resolution and decreasing the solver processing time, OEMs are moving forward from the road, to the lab and today to CAE.

Abstract The installation of essential systems into aircraft wings involves numerous labour-intensive processes. Many human operators are required to perform complex manual tasks over long periods of time in very challenging physical positions due to the limited access and confined space. This level of human activity in poor ergonomic conditions directly impacts on speed and quality of production but also, in the longer term, can cause costly human resource problems from operators' cumulative development of musculoskeletal injuries. These problems are exacerbated in areas of the wing which house multiple systems components because the volume of manual work and number of operators is higher but the available space is reduced. To improve the efficiency of manual work processes which cannot yet be automated we therefore need to consider how we might redesign systems installations in the enclosed wing environment to better enable operator access and reduce production time. This paper describes a recent study that applied design for assembly and maintainability principles and CATIA v5 computer aided design software to identify small design changes for wing systems installation tasks.

A new Formula for racing The new Formula E series' electric racecars are intended to pioneer new technology for broader use in production, encouraging fans to think differently about the technologies they use. Production of satellite with first all-electric propulsion system advances Electric propulsion has been limited so far to small movements of the satellites once it is in its geostationary orbit. The Boeing 702SP innovation is its use of electric propulsion to raise the satellite from its launch-vehicle drop-off point to geostationary orbit. Using CAE to assess whining noise of electric powertrains To develop an electric powertrain with a minimum noise level and minimized whining it is necessary to have accurate CAE simulation and precise criteria to assess whining noise.

This SAE Recommended Practice describes how to position and posture the H-point design tool (HPD) described in Appendix B, and how to establish the seating reference point (SgRP), design H-point travel path, and other key reference points that are used in the design and specification of both driver and passenger seat positions. This practice also provides a method for determining the length of the seat track for a driver seat that adjusts fore/aft. The seat track length is based on a desired level of driver accommodation, assuming a U.S. population containing an equal number of male and female drivers. The procedure can be used to establish driver seat track accommodation for new vehicle designs or to evaluate accommodation in existing vehicles. A general method for determining driver seat track length for any driver population (male and female stature distribution) at any selected accommodation percentile and gender mix is given in Appendix A. Application of this document is limited to Class A Vehicles (Passenger Cars, Multipurpose Passenger Vehicles, and Light Trucks) as defined in SAE J1100.

This document provides dimension definitions that facilitate geometric quantification and evaluation of seats. This document has been designed for use in CAD, however, many dimensions require establishing HPM position and attitude. Refer to the appropriate document for these procedures. These dimensions are package independent in that they do not require use of the HPM-ll supplemental thigh/leg/shoe. Three types of seat geometry reference points and measurements have been developed. 1. Simple reference points and measurements not related to H-point 2. H-point dependent reference points and measurement that utilize the seat characterization capabilities of the HPM to quantify seat measurements 3. Cross sectional seat trim outlines For convenience and simplicity, many terms associated with H-point devices use human body parts in their name. However, they should not be construed as measures that indicate interaction with any or all occupants concerning accommodation, human capabilities, or comfort.
