RAMSIS Industrial Vehicles is a CAD manikin, especially developed for the ergonomic design of drivers' workplaces during the construction phase of so-called commercial vehicles, like heavy machinery, construction machinery, excavators, wheel loaders, etc. However, it is not just the posture and safety of the driver that can be optimised based on ergonomic analyses, the entire design of a vehicle can also be checked in order to check exactly how maintenance work will be carried out.
Detailed statistic knowledge about persons' body measurements and behavior is absolutely essential if an exact representation of a future "target customer" is to be created. Extensive research projects with real persons have enabled the reproduction of widely differing groups of persons and their behaviour in an industrial vehicle, and the integration of the subsequent results in the RAMSIS databases.
RAMSIS Industrial Vehicles therefore has a wide spectrum of anthropometric data of the most important global regions, for example Asia, North America and Europe. Easily operable statistical functions enable the generation of digital images of customer groups and the images' integration into the entire construction/heavy machinery design and product development process.
During the course of extensive experiments, research institutes have analysed the postures and behaviour of the operators of these heavy machines. Thanks to the embedding of the acquired information into the "Truck" posture model, the posture of the driver can be simulated and realistic forecasts with regard to future room and operating conditions within the vehicle can be made. Further posture models like the standing posture model or the passenger posture model are also available and can be used according to the design process applications required.
After positioning of the RAMSIS manikin in the work environment, the user has widely differing analysis functions to choose from - like the calculation of space and room needs, accessibility envelopes, direct and indirect (mirror) manikin view and the simulation of posture-contingent maximum available force. These analytical functions provide the user with extensive information about the ergonomic quality of the product and possible critical aspects of its design.
So questions like...
- Has the driver a sufficient field of view to see even small persons in the vicinity of the vehicle?
- Are all operating elements or pedals easy to access?
- Can the mechanic carry out all relevant hand and arm movements during maintenance, or how much maximum force can he apply?
- How comfortable (or uncomfortable) are the various seating positions?
...can be clearly answered thanks to RAMSIS - before the construction of the first prototype. That really saves time and money!
Depending on the specific platform on which RAMSIS has to run, the software can be easily and efficiently integrated into your development process chain. RAMSIS is available as a stand-alone version on UNIX or Windows platforms and as a fully integrated ergonomics tool in CATIA V5 and V4.
