Assessment Method of Machinery Technical Safety in the Aspect of Virtual Commissioning of Machines

New technologies used for construction and upgrading formulate new research tasks. That is why the consideration of new solutions, methods and acquisition of new information in this respect is an important aspect which contributes to the progress of knowledge in this area. This paper applies to one of the issues, namely the assessment method of machinery technical safety. It presents the essential aspects related to legislation, risk assessment and analysis and selection of the risk reduction model. Solving of the problem is important because the difficulty occurring in the process results in ambiguous assessments and may generate additional hazards in the system, causing a reduction in the safety level. On the stage of assessment and reduction of the risks which occur in the mechatronic system, one can refer to the formal and legal area, which describes the harmonisation mechanism, but the relevant types and methods used for conducting a hazard analysis, as well as risk assessment tools, can be selected in any way, depending on the system safety engineer’s expertise. The authors recommend that a uniform assessment method of the machinery technical safety should be adopted, which will help to model cohesive virtual models developed for the needs of virtual technical commissioning.
