At present,the domestic ice and snow industry is still in its infancy,and the country heavily relies on imports for some professional-level ice and snow equipment,especially professional skis.In order to break the monopoly of foreign products,this article will adopt the method of reverse design and take a foreign professional ski as a template.Use new materials to produce new skis with independent intellectual property rights and skis binding with shock absorption function to meet the needs of domestic athletes.Firstly,this paper analyzes the overall force of the two motion states of skiing straight and turning,and establishes the formula of the impact force in each direction during the sliding process.At the same time,on the basis of the overall force analysis,the force is further converted to the holder and the ski shoe for analysis.Through the analysis,the formula of the breakaway torque and the relationship between the clamping force generated by the holder and the impact force are established.Finally,a mechanical model of stiffness distribution is established by analyzing the stiffness factors that affect the motion state.Secondly,according to the equipment design requirements and TRIZ theory analysis,the structural design of the new ski was completed through structural analysis and stiffness analysis under the conditions of FIS regulations: the new ski is composed of GLARE ply and different components of the spliced core,while the bindings of the new ski were analysed using force analysis to determine the bindings need to have vibration damping function.The design of the new bindings was completed in accordance with the thickness limits of the FIS.Finally,solidworks is used to establish a three-dimensional model of the snowboard,and three-point bending simulation analysis is given to different material properties of the core through ansys workbench.The rigidity performance of different splicing cores is determined through the simulation data,and then the core material of the new type of snowboard is determined.The cantilever beam test method is used to carry out the segmented test,and the experimental data verifies that the performance of the new snowboard can reach the performance of the target professional-grade snowboard.In the same way,two softwares are used to perform three-dimensional modeling and vibration reduction simulation of the vibration damping structure of the fixture.The vibration reduction effect under the simulated working conditions is confirmed through the simulation,and 3D printing technology is used to print the sample of the fixture.Referencing the simulation constraint conditions test the vibration damping structure of the fixture,and verify the reliability of the simulation results according to the test data.The performance of the new type of snowboard produced by reverse design can reach the performance of the target international professional snowboard,and it can be based on the characteristics of different competition events and user requirements.Due to the use of new materials in the country for production,the price is lower than that of foreign skis with the same performance.
