Design And Research Of New Type Anti-riot Vehicle Intercepting Device

As one of the major safety facilities,the vehicle barrier is effective in protecting the customs,airports,prisons and government agencies.Be able to resist and intercept the forcible intrusion of terrorist vehicles,ensure the safe and smooth operation of key areas,ensure the safety of life and property,reduce the loss to the minimum.Although the application range of the car is very wide,but in our country,there are still restricting the rapid development of factors,or function is not perfect,or expensive,or low reliability,or bulky.Therefore,the development of a compact,reliable,cost-effective car block is of great social value.On the basis of the research and analysis of the current situation of the development of the domestic and foreign various kinds of vehicles,this paper develops a new type of anti-riot gear.This paper focuses on the new structure design of the new type of anti-riot vehicle,and adopts the dynamic research theory and simulation analysis technology.Through theoretical analysis,calculate the relevant structural parameters of riot car bumper,with each part of the riot car of 3D digital modeling and virtual assembly of 3D modeling software SOLIDWORKS,using ANSYS to block anti-riot vehicles key components of stress analysis and modal analysis,in order to further optimize the structure and improve the performance.Mutual authentication through AMESim simulation and experiment on the structure and function of the product of continuous improvement,finally obtained with a simple structure,high strength,low cost and stable operation,in response to new anti-riot vehicle speed and stable performance of the block.At present,the product can achieve a series of promotion,has broad market prospects.At present,the new anti-riot gear unit has been applied and popularized in a number of prisons in Shanghai City,and the product has obtained the appearance patent(CN301453498S)and the utility model(CN203034397U).
