“…This muscle model requires only the definition of the initial muscle force; the rest of the parameters are modelled according to the assumptions of the Hill-type model (Hill, 1938;Zajac, 1989). Previous studies found good agreement between the simple muscle model and more parameter-intensive models when slower movements are simulated (Damsgaard et al, 2006;Duprey et al, 2015). The simple muscle model basically ignores the differing behaviour of non-contractile elements (e.g.…”

Insects show a great variety of mouthpart and muscle configurations; however, knowledge of their mouthpart kinematics and muscle activation patterns is fragmentary. Understanding the role of muscle groups during movement and comparing them between insect groups could yield insights into evolutionary patterns and functional constraints. Here, we developed a mathematical inverse dynamic model including distinct muscles for an insect head-mandiblemuscle complex based on micro-computed tomography (µCT) data and bite force measurements. With the advent of µCT, it is now possible to obtain precise spatial information about muscle attachment areas and head capsule construction in insects. Our model shows a distinct activation pattern for certain fibre groups potentially related to a geometry-dependent optimization. Muscle activation patterns suggest that intramandibular muscles play a minor role in bite force generation, which is a potential reason for their loss in several lineages of higher insects. Our model is in agreement with previous studies investigating fast and slow muscle fibres and is able to resolve the spatio-temporal activation patterns of these different muscle types in insects. The model used here has a high potential for large-scale comparative analyses on the role of different muscle setups and head capsule designs in the megadiverse insects in order to aid our understanding of insect head capsule and mouthpart evolution under mechanical constraints.

Digital human modeling tools support proactive ergonomics in optimizing work tasks and workplace layouts. Empirical-statistical model based tools are often used to estimate the force exertion capability of the operators. This work is intended to serve as an initial probing into the usability of a musculoskeletal model based software, AnyBody Modeling Systems (AMS), in evaluating the force exertion capability at different points in the workspace and for various exertion directions. As a first step, it focuses on the modeling approach and the accuracy of one-handed isometric strength estimates of AMS. An existing literature database was used to compare the predicted strength at 8 hand locations and in 26 exertion directions, while simulating the empirical postures. The results show a correlation coefficient of 0.7 between the simulated and the experimental strength. AMS emphasizes the biomechanical advantages in strength due to the alignment of force exertion direction with the shoulder. Additionally, some discrepancies have been identified and discussed.

“…Due to the lack in the low cost predicting methods for observing biomechanical load on an operator during production in a workplace, Laring et al [10] developed an ergonomic complement system that gives a first insight into the future ergonomic quality of a planned production; such that by initially identifying the events causing high biomechanical load on the operator, the production engineer gains the opportunity to redesign the process. Duprey et al [11] discussed the challenge of measuring electromyographic (EMG) data in the field for the estimations of the muscular activations to ergonomically assess occupational tasks. The upper limb musculoskeletal (MSK) model from anybody was used for the prediction of joint reactions and muscle activations during a push force exertion task.…”

Because of their technical advantages over ordinary metal springs, gas springs find usage in wide range of applications from furniture to aerospace industry as lifting, lowering or damping assists. Their integration to the tailgate operations in automotive industry is a challenging area, where not only the fundamental gas spring characteristics but also the mounting settings, working environment and tailgate body structure should be considered. The design and integration of these components will determine manual force exertion of operators thus the consideration of ergonomic characteristics of different populations is crucial. This paper introduces a recent visual academic software package, entitled TEM-SOFT, which is developed as a part of this research to perform ergo-mechanic simulations of tailgate operations with a fast, reliable and contemporary engineering approach and it is suitable for engineers and under-post graduate level students of mechanical and industrial engineering programs in the universities. The software developed and presented in this paper features all aspects of tailgate-gas spring operations considering the assembly scheme, tailgate mass center, gas spring type and working temperature in order to compute the required manual forces and the individual and combined impacts of acting parameters. Sufficient amount of scenarios were considered and the results were evaluated and discussed extensively. In addition to the other key findings, conducted research has shown that stronger gas springs, more effectively tend to move the critical tailgate position angle-where no operator force is needed to keep the tailgate opening-to the initial phases of the opening operation. A trade-off of this benefit is a superior initial manual force during closing.
