| Snow remover (also called snow plow) is the special equipment used for cleaning up the snow and ice on the roads to ensure the communication safeties. In China, the snow coverage is very large in winter. The tasks of removing the snow and ice on roads are very demanding, so the snow removers have a very big market. With our country's economic development, more and more freeways, crossroads, airfields were built. But, the removers we currently have are too few to satisfy the market needs. On the other hand, the imported new-types snow removers are very expensive and have to wait for a long time for the after services.Last but not least, these imported machines can't adapt well our country's road situations. From all of above, it could be seen that it has great important significance and economic advantage to develop ourselves snow removers that fit our country's snowing coverage.This research was performed with the sample vehicle——DQX multifunction snow remover, which is the research program of the Sate Economic and Trade Commission. The single-direction plows are the most popular of all types'equipments of the snow removers. With regard the front shovel, the main research tasks are the structure design, the space shape design of the shovel surface, the research of the spring obstacles-avoiding mechanisms, the matching calculation and analysis of the whole truck's capacities. As the ranges of the physical properties values of the snow are very large, and the road conditions are very complex, the design, analysis, and calculation of the snow removers have the characters of the experimentations and practices. To save the resources and shorten the development cycle, these research methods were adopted, such as, using UG software to build the model, analyzing the removed snow's track directly on the model, using Adams to simulate the structure of avoiding obstacles, and using relative experience data to calculate the whole... |
