The desire for more quiet and comfortable cars from consumers requires better engineering in the process of engine mount development. The fact that no physical vehicle exists at the time when the project launches, the design guidance relying on computer-aided engineering is essential. This paper discusses an engine mount development approach relying on computer-aided engineering with the assumption that the initial powertrain data, which include the powertrain mass, mass center, mass moment of inertia and engine power, are available. The mount placement strategy is discussed after the torque roll axis is introduced. To achieve the decoupled vibration modes for the mounting system, the computer simulated powertrain rigid body modal analysis is employed. As a result, the mount linear portion of the load-deflection curve is determined while the nonlinear portion is chosen by static analysis, whose constraint is the maximum powertrain roll angle under the condition of the maximum torque input. Also, the reaction forces in the three orthogonal directions are able to be estimated under the various loading conditions which reflect the vehicle driving conditions. Finally, finite element analysis is employed in the designs of the metallic and rubber components to meet the durability and performance requirements.

Finite element modeling (FEM) plays a significant role in the design of various devices in the engineering field of automotive, aerospace, defense etc. In the recent past, FEM is assisting engineers and healthcare professional in analyzing and designing various medical devices with advanced functionality. Computer aided engineering can predict failure circumstances, which can be avoided for the health and well-being of people. In this research work, computer aided engineering analysis of human elbow is presented beginning with modeling of human elbow from medical image data, and predicting the stresses in elbow during carrying heavy loads. The analysis is performed by using finite element method. The results predict the stress level and displacement in the human bone during heavy weight lifting. Thus, it can be used to predict the safe load that a particular person can carry without bone injury. The present analysis focused on a particular model of bone for a particular individual. However, safe load can be determined for various age groups by generating more detailed model including tendons, ligaments and by using patient specific material properties.

Aided Design

Success of the design process hinges on efficient communication between the various functions involved. Traditionally this communication has been ‘paper based’ with information passing between sales, design, production and manufacture to describe the complete history of the product. This complex interaction between the functions depends on the availability at each stage of the most up-to-date and accurate information. The paper based system has many shortcomings in this respect particularly the inability of the designer to assess interactively the effect of any changes he may make on the cost, delivery, quality and performance of the product. The use of computer aided design as a central part of the computer aided engineering system allows a company greatly to improve communications during a project by giving the engineer a way of providing accurate information more quickly to each adjacent function while receiving feedback on the effectiveness and suitability of the product in a fraction of the time.

The present paper presents an integrated computer-aided engineering (CAE) approach combining digital imaging, solid modeling, robust design methodology, and finite element analysis in order to conduct a parametric investigation of the design of locked plating systems. The present study allows for understanding the contributions of different design parameters on the biomechanics and reliability of these systems. Furthermore, the present approach will lead to exploration of optimum design parameters that will result in robust system performance. Three-dimensional surface models of cortical and cancellous femoral bone were derived via digital computed tomography (CT) image processing techniques and a medical imaging analysis program. A nine orthogonal array matrix simulation (L9) was conducted using finite element methods to study the effects of the various design parameters on plate performance. The introduced technique was demonstrated and experimentally verified on a case study using a Smith & Nephew PERI- LOC distal femur locking plate and a Synthes Less Invasive Stabilization System (LISS).

Fatigue life of automotive engine mount insulator made of natural rubber was evaluated. In order to develop an appropriate fatigue damage parameter of the rubber material, a series of displacement controlled fatigue tests was conducted using 3-dimensional dumbbell specimens with different levels of mean displacement. It was shown that the maximum Green-Lagrange strain was a proper damage parameter, taking the mean displacement effects into account. Nonlinear finite element analyses of the rubber engine mount insulator and 3D dumbbell specimen were performed based on a hyper-elastic material model determined from the simple and equi-biaxial tension tests. Fatigue life prediction of the engine mount insulator was made by incorporating the maximum Green-Lagrange strain values, which was evaluated from the finite element analysis and fatigue tests, respectively. Predicted fatigue lives of the engine mount insulator showed a fairly good agreement with the experimental fatigue lives.

Effectiveness Of Training

The primary objective of the Computer-Aided Engineering (CAE) course that is a required course during the third year in the mechanical engineering curriculum at Binghamton University is to educate students in engineering design. The benefits and limitations of computer-aided engineering design are stressed. Pro/Engineer® is used as the basis of this course. It integrates solid modeling, motion analysis, and finite element analysis. As a means to the objective of teaching engineering design, students must first be trained to use the software. The effectiveness of the software training and design education was assessed using a project that is repeated (although modified) each time the course is offered. This is often referred to as a “marker assignment.” The marker assignment in this case is an aircraft landing gear design and analysis. In this paper, the effectiveness of training videos for design education is examined using the marker assignment approach. Data for three semesters is used. In each semester a different method of presentation was used: (1) traditional in class lectures only, (2) only recorded videos distributed to students, and (3) recorded videos distributed to students combined with summary in-class lectures. The changes to the course that were adopted based on the assessment are presented. In addition, the results of a survey of student satisfaction with the video format used in the course are presented.
