During the process of defining suitable design solutions, a designer has to consider a wide range of influential factors. Ergonomics certainly belongs to more complex ones. Less experienced designers could encounter several problems during this design stage. Although some literature can be found about ergonomic design of hand tools, a designer still has to have amassed quite a lot of experience and knowledge in the field of ergonomic, in order to choose and carry out appropriate design and redesign actions. Existing computer tools for ergonomic design are not able to assist a designer with higher level advice within design process. An intelligent decision support system has been developed in order to overcome this bottleneck. This paper presents a knowledge base, containing ergonomic design knowledge specific for hand tools design. A pneumatic hammer handle design is used as a case study to show how ergonomic design knowledge built in the system is used to improve the ergonomic value of the product.

Road traffic accidents cause one of the highest numbers of severe injuries. Virtual human body models play an important role to assess the injuries during impact loading especially for scenarios, where complex dynamical loading is taken into account. It concerns mainly vulnerable road users, where motorcyclists are addressed. The risk of fatal injuries connected to motorcycle usage is still one of the biggest among all modes of transportation. Due to a complicated interaction between a motorcycle and an opposite vehicle during their crash, the virtual approach is an optimal way towards a crash reconstruction. The presented work shows the exploitation of virtual a human body model in the injury assessment during the motorcycle against car accident using the virtual approach by the numerical simulation. The study exploits an existing human body model as a helmeted motorcycle rider, couples it to a motorcycle model and runs a simulation, where the motorcycle impacts an opposite vehicle according to a real case. Injury assessment and comparison to the real case is analysed. The paper shows the advantages of the virtual approach in a complex impact scenario reconstruction in order to optimize the personal protective equipment for injury risk reduction in future transport.

“…In developing these effective passive safety measures, a clear understanding of the behaviours of motorcycles and riders when they interact with the opposing vehicle during crashes is of the utmost importance. There was a great deal of work devoted to studying the kinematics of motorcycle and rider, and the distributions and mechanisms of the injuries in crashes (Chinn et al, 2001;Toma et al, 2010;Serre et al, 2012;Carmai et al, 2019). Most of such works were focused on frontal, or Type I collisions, in which a motorcycle crashed directly onto an opponent vehicle because it has been well known to be the severest type of road crash.…”

Motorcycle frontal crashes usually cause serious and fatal head injuries to riders. This paper presents a two-level factorial experiment through finite element simulations of motorcycle-rigid wall impact scenario to investigate the effects of motorcycle layout design variations on rider's relative head injury risks, and also of the deformation mechanisms of motorcycle frontal structures on dynamics of the motorcycle. The motorcycle layout design variations were represented by the changes of three design factors, namely location of the engine block, location of air filter casing and its orientation. Head Injury Criteria (HIC15) based on a time interval of 15 ms were selected as the response variable to evaluate the effects of the corresponding changes. The analysis showed that HIC15 values were significantly influenced by the changes of these factors, with the differences ranging from -21% to +11% for seven different designs of motorcycle layout as compared to the original one. Such influences on HIC15 values were mainly due to the changes in motorcycle dynamics caused by different deformation mechanisms of the wheel, which was attributed to interactions between the frontal structures and the engine block and also air filter casing. It was also found that HIC15 values were significantly influenced by the vertical component of motorcycle accelerations, but not by the horizontal component. A regression model for predicting the HIC15 value was established and the effect plots of the factors were also produced from the factorial analysis and it was found that there were interactions between the effect of the design factors. The outcomes of the present study provide an insight into how the structural response of the frontal structures of motorcycles could be taken into consideration as part of design elements in reducing rider's head injury risks in frontal crashes.
