Innovative Design Of Sliding Bearing Test Bench Based On TRIZ

Sliding bearings are important parts in mechanical equipment.With the rapid development of industry,the shafting structure and working environment of mechanical equipment are becoming more and more diversified.The existing test equipment cannot meet the test requirements under diversified working conditions.Innovative design of bearing test bench is required.As a theory of invention problem solving,TRIZ has distinct characteristics and advantages.The practice of major domestic and foreign companies has proved that the use of TRIZ can greatly accelerate the process of people’s creation and invention,and can obtain high-quality innovative products.This paper takes TRIZ as the theoretical basis and takes the teaching sliding bearing test bench as the goal.Two innovative design schemes are proposed and the structural design is carried out.The feasibility of the scheme is verified through simulation,and finally the maturity of the sliding bearing test bench product was predicted and the evolution direction of the product was analyzed.The main contents of the paper are as follows:Firstly,based on the TRIZ theory,an innovative design process for sliding bearing test benches was established.On the premise of in-depth understanding of the tools in TRIZ,with function-oriented and the scientific effect library as the main source of knowledge,a set of innovative design procedures for sliding bearing test benches that can be implemented from the design goal to the final plan are proposed.Secondly,based on the teaching sliding bearing test bench,the design goal of applying variable load and increasing thrust sliding bearing test are put forward for its insufficient function.Inspired by the above-mentioned innovative process,a conceptual scheme is generated,the structure is designed,and Creo is used to build a three-dimensional model.Thirdly,using the finite element simulation software ANSYS Workbench to perform multi-body statics simulation on the designed structure to obtain important parameters such as stress and deformation of key components under different working conditions.These parameters are analyzed to verify the designed sliding bearing test bench can work normally under different working conditions.Fourthly,using the theory of technological system evolution in TRIZ,the technical system maturity of sliding bearing test bench products is predicted through four representative indicators: patent grade,number of patents,number of patents that make up for defects,and number of patents for cost reduction,judging that the current sliding bearing test bench is in the mature stage of the product life cycle,and according to the evolution law corresponding to the mature period and the adjacent decline period,it is predicted that the sliding bearing test bench will evolve towards microcosmic and multi-functional integration.
