The Crankshaft Wear Theory Predicts Of Cylinder-in-line Engine

At the age of increasingly tense energy supply, the automotive industry which plays an important part in energy consumption, is facing a sever challenge; to decrease the energy consumption without decreasing the workload. In order to achieve this target, we must decrease the friction loss among mechanical parts of vehicle. We need to minimum the wear among parts of engine when it works, as it’s the main part of a vehicle. To this end, we must understand the wear to provide a basis on how to avoid the loss.In this case, this article is going to take cylinder-in-line engine as example, firstly the stress of the crank connecting rod mechanism analysis would be done, then the bearing load and journal load of connecting rod end and main shaft in crank-link mechanism would be calculated based on the stress analysis at first stage. According to the calculation, we can draw bearings, journal of the load condition, and then to predict the wear distribution. In the load analysis process, we use quality focused approach, there will be associated with irregular side part of the quality equivalent to a certain part of the focus on in order to facilitate quality operations. In a working cycle, because of the size and direction of the load is changing, in order to facilitate the calculation, we take a point of view as a step to calculate a range of loading values and orientation.According to load analysis, we would know the distribution of the wear. Later, design corresponding FORTRAN program according to the numerical calculation process. After the program is completed, input original data, test run, determine the accuracy of the program. Finally, we can draw bearings, journal of the load chart and wear map.Based on analysis of load charts and wear map, you can understand the bearings, journal of wear for the correct choice of materials and organizations to provide a basis for forced feed lubrication.
