We constructed artificial road sections (2.0 m long, 0.55 m wide and 0.35 m deep) with loessial soil packed to give a representative bulk density of 1.5 g/cm3, and with different slope gradients (6°, 9°, 12°, 15° and 18°). Ten sections were planted with 50% grass coverage and another ten were bare as control treatments. Simulated rainfall (120 mm/h for 1 hour) was applied to the road sections and the hydraulic characteristics of the overland flow generated, and the amount of runoff and sediment yield produced over time, were examined. For any given slope gradient, grass inhibited overland flow as indicated by lower Froude and Reynolds numbers, higher friction and surface roughness as indicated by Manning and Darcy-Weisbach coefficients, and lower mean flow velocities. Lower impact energies of raindrops intercepted by the grass led to less surface seal formation and detachment of soil particles. This in turn resulted in amounts of runoff and sediment from the grassed roads with different slope gradients, which were 7.7%~13.1% and 47.3%~60.4% smaller than those from the bare roads, respectively. Reductions in sediment yields, which were linearly related to the slope gradient, were also attributable to reduced carrying capacity of the runoff. Therefore, grass growing on loessial earthen roads can mitigate soil losses effectively and, to a lesser degree, runoff amounts.","PeriodicalId":353239,"journal":{"name":"2010 WASE International Conference on Information Engineering","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130029177","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}

This paper analyzes the influence mechanism of dynamic unbalance to vibration and noise of rotor axis in MDRVPs, and calculates the vibration deformation of the rotor axis caused by dynamic unbalance through the finite element method. Moreover, a series of experiments on noise source identification are carried on a MDRVP sample machine varying the amount of dynamic unbalance. Through the experimental results, conclusions are drawn that the periodic incentives generated by the unbalance of rotor axis are the main attribution of vibration and noise. Therefore the noise reduces when the amount of unbalance of rotor axis deceases. However, when the allowable unbalance of the rotor axis decreases to a certain degree, aerodynamic noise generated at the outlet becomes the main noise with dominant frequency. It is true that noise of MDRVPs should be no more than 72dB, so the allowable amount of dynamic unbalance should be chosen at a moderate lever as 1.0 g•mm/kg. In that way, this conclusion offers a rule for MDRVPs design and dynamic balance operation because this lever would not only meet the demand of noise reduction but also save working hours and cost for dynamic balancing.","PeriodicalId":353239,"journal":{"name":"2010 WASE International Conference on Information Engineering","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130073997","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}
