Influence of aerodynamic lift and centre of pressure position in motorcycle stability 气动升力和压力中心位置对摩托车稳定性的影响

{"title":"Influence of aerodynamic lift and centre of pressure position in motorcycle stability","authors":"Benjamín González, Felipe Vasquez","doi":"10.59490/649e491f3e542128d59873c2","DOIUrl":"https://doi.org/10.59490/649e491f3e542128d59873c2","url":null,"abstract":"Motorcycles are systems with complex dynamic behaviour that can become unstable under certain driving conditions. Avoiding such instabilities from the design stage is not trivial since they depend on various interrelated parameters, one of which is aerodynamics. Aerodynamic forces in a vehicle can be essentially described by its longitudinal (drag) and vertical (lift) components together with its point of application on the vehicle, known as centre of pressure (CoP). Several studies had shown that aerodynamic forces have an influence on stability. Several authors explain that drag influences stability through four mechanisms: dampening lateral motion, and changing weight distribution, tire cornering stiffness, and rake geometry. It is well known that in motorsport performance needs to be enhanced continuously and aerodynamics can be used to this end. Changing the CoP position and the addition of lift force certainly affect the four mechanisms described by (Meijaard, 2006), but their effect on stability had not been described in the literature. Therefore the aim of this research is to extend on (Meijaard, 2006) research, by analysing the influence of CoP position and aerodynamic lift in motorcycle stability in straight line and steady cornering. To this end, we perform a stability analysis on a motorcycle with variable CoP and lift. We consider the CoP ahead, aligned, and behind the motorcycle centre of mass, and in cornering we consider it on both sides of the symmetry plane of the motorcycle to account for rider lateral displacement. The result contributes to the understanding of motorcycle aerodynamics providing new insights into how to use aerodynamics to enhance stability.","PeriodicalId":141471,"journal":{"name":"The Evolving Scholar - BMD 2023, 5th Edition","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128588922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To fill this gap, we have developed BRiM, a modular and extensible open-source framework for creating Bicycle-Rider Models. It uses an established bicycle model, like the Carvallo-Whipple model, which can be extended using components from BRiM's extensive library, or user-defined custom subclasses. It leverages the open-source Python package SymPy, a computer algebra system, to compute the equations of motion. This results in symbolic equations of motion, which, after code generation, can be used to simulate and optimise the model. The effectiveness of BRiM is demonstrated by solving a trajectory tracking problem using a direct collocation algorithm.","PeriodicalId":141471,"journal":{"name":"The Evolving Scholar - BMD 2023, 5th Edition","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128633403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
