Although simulation has become a very important aspect in product development today, a study of current design methodologies by Dohr and Vielhaber has shown that there is currently no methodology fully incorporating simulation within the context of mechatronic product development. The results of this study are used to derive specific needs of a simulation-based design process. Based on these requirements a process model for simulation-based mechatronic design is developed which is based on process steps of established design methodologies. In order to integrate simulation, the process model consists of two activity streams: analysis activities are linked to the specific design activities of mechatronic systems. Based on these two streams guidance is provided on which simulation technique should be used for specific activities and how the results from the simulation have to be handled in order to improve design without macro-iterations. With regard to mechatronic interdisciplinarity as well as data and model management, the use of a system model as a platform for the exchange of information and knowledge is integrated into the process model. Finally an outlook on future work regarding the detailing of the process model as well as on the application of the process model is provided.

Dependency Model

Mechatronic design is traditionally supported through domain-specific design activities throughout the product development process. The partitioning into domain-specific problems leads to a situation where product properties influence each other, hence giving rise to dependencies. These dependencies play a key role in the prediction of properties and, as a result, in the decision-making process. The important question is how to manage the dependencies for efficient and effective decision making? The aim of this paper is threefold. First, we investigate the nature of dependencies and study how to model them. The paper proposes appropriate terminology taking into account the synthesis and analysis nature of both the properties and the dependencies. This terminology will be the core of the new dependency modeling language. The concepts related to dependency modeling are then illustrated through a simple robot design example, where the creation and importance of a dependency model are explained. Second, we study practical approaches for consistency management and model management in the presence of dependencies. Six levels-of-detail in modeling dependencies are presented; emphasizing that modeling at a higher level-of-detail ensures that more inconsistencies are avoided. Available languages such as OMG SysML™ are evaluated for a possible creation of the dependency models leading toward executable dependency networks. However, at present, SysML does not provide sufficiently rich language constructs to model dependencies. Third, we compare our dependency modeling approach to other state-of-the-art approaches such as dependency modeling with a design structure matrix (DSM), and highlight the benefits of the terminology proposed in this paper. We aim to convince the reader that there is substantial value in modeling dependencies explicitly, especially to avoid inconsistencies, which is not the current state of practice. However, an overall value from dependency modeling can only be obtained if the cost of creating the dependency model is reasonable. Issues such as human interaction/effort and model management through product lifecycle management (PLM) are discussed.

With the identification of profitable freight areas and the selection of growth traffics for development has come the need to review in detail the running gear and, in particular, the suspensions of both 4-wheeled and bogie vehicles. This design review has been aimed at ensuring a high-speed capability for all new freight vehicles coupled with safety at all times, low maintenance costs, and maximum availability. After reviewing traditional suspensions, in wide use, with reference to their known strengths and weaknesses, the paper discusses in some detail the philosophy now being applied in B.R. design offices to new freight running gear, for both 4-wheeled and bogie vehicles, to ensure satisfactory achievement of technical objectives. Examples of new developments are provided, together with comments on progress to date.

The Relationship

The appropriate iteration process model is the basis for managing and optimizing the product development process. In this article, we attempt to introduce the concept of process effectiveness and process value. The relationship between rework probability and process effectiveness is discussed. The evolution function of process effectiveness is proposed to drive the overlapped iteration process of multi-coupled activities. The evolution process with input information update is studied, and a simulation model is presented to obtain the accurate iteration process of development. It is useful to analyze the risks during development, and has good flexibility and versatility. The calculation method of process value for overlapped iteration process is given, and an optimization model for product development process is provided. The model is used to improve the development process of the stamping die of a car roof. With the model, we can get a suitable overlapping rate of multi-coupled activities to improve development performance.

Lifecycle Design

Sustainable product development (SPD) requires that product design achieve minimal or zero environmental impact, while satisfying other design criteria such as functionality, quality, desirable features, and acceptable cost and time to market. Therefore, environmental evaluations must be incorporated into the design stage. This research is aimed at the development of a new approach to lifecycle design and evaluation. This paper proposes a framework to optimize functional, environmental, and economic (FEE) performance towards sustainable design. Based on the three dimensions of FEE, a systematic lifecycle design process model is proposed, which consists of: the three FEE requirements; two design objects (physical structure and lifecycle structure); and, the FEE evaluation streams of LCQ (functional lifecycle quality), LCA (environmental lifecycle assessment) and LCC (economic lifecycle costing). A new concept, called process-based analysis (PBA) is defined, and used as the base for FEE evaluations.

Starting Point

The importance of the concept development phase in product development is contradictory to the level and amount of current computer-based support for it, especially with regards to mechanical design. Paper-based methods for conceptual design offer a far greater level of maturity and familiarity than current computational methods. Engineers usually work with software designed to address only a single stage of the concept design phase, such as requirements management tools. Integration with software covering other stages, e.g. functional modeling, is generally poor. Using the requirements for concept models outlined in the VDI 2221 guideline for systematic product development as a starting point, the authors propose an integrated product model constructed using the Systems Modeling Language (SysML) that moves beyond geometry to integrate all necessary aspects for conceptual design. These include requirements, functions and function structures, working principles and their structures as well as physical effects. In order to explore the applicability of SysML for mechanical design, a case study on the design of a passenger car’s luggage compartment cover is presented. The case study shows that many different SysML diagram types are suitable for formal modeling in mechanical concept design, though they were originally defined for software and control system development. It is then proposed that the creation and use of libraries defining generic as well as more complicated templates raises efficiency in modeling. The use of diagrams and their semantics for conceptual modeling make SysML a strong candidate for integrated product modeling of mechanical as well as mechatronic systems.

The development of complex products with high quality in dynamic markets requires appropriate robust design and tolerancing workflows supporting the entire product development process. Despite the large number of methods and tools available for designers and tolerance engineers, there are hardly any consistent approaches that are applicable throughout all development stages. This is mainly due to the break between the primarily qualitative approaches for the concept stage and the quantitative parameter and tolerance design activities in subsequent stages. Motivated by this, this paper bridges the gap between these two different views by contrasting the used terminology and methods. Moreover, it studies the effects of early robust design decisions with a focus on Suh’s Axiomatic Design axioms on later parameter and tolerance optimization. Since most robust design activities in concept design can be ascribed to these axioms, this allows reliable statements about the specific benefits of early robust design decisions on the entire process considering variation in product development for the first time. The presented effects on the optimization of nominal design parameters and their tolerance values are shown by means of a case study based on ski bindings.
