Comparative study for static analysis of connecting rod for different materials.[1]

Past Work Relevant to Appropedia[edit | edit source]

  • Designed crankshaft and performed static structural and fatigue analysis on ANSYS.

Designed the crankshaft on PTC Creo software using appropriate dimensions. Meshing was performed on ANSYS with overall tetrahedral mesh over the body after multiple iterations. Mesh quality was decided on various factors like Aspect Ratio, Skewness, and Jacobian ratio. Appropriate boundary conditions were applied based on actual working. In Static Analysis, results for total deformation and equivalent stresses were obtained. In Fatigue Analysis, the life of the crankshaft was calculated using various tools like fatigue sensitivity, factor of safety, and bilinearlity indication. Optimization was performed by creating three new concepts where material from the minimum stress concentration areas was removed. Finally, one concept was finalized out of three for which the stress concentration was reduced and 9.11% reduction of weight was obtained.

  • FE Analysis of connecting rod of Toyota Yaris for cost and material optimization.

Identified the different materials from which the connecting rod is made or can be made. Designed the connecting rod on Solidworks according to the dimensions of the connecting rod used in Toyota Yaris. Performed static structural analysis on the connecting rod for different loading conditions. Calculated the areas of excess stress concentration and refined those areas. Calculated the life of the connecting rod and found a 6.9% reduction in its weight.

  • Improvement in toy car manufacturing process using lean tools.

Constructed a Current State Map based upon the current processes and calculated the production lead time and takt time. Prepared Standardized Work Combination Sheets for each work station and mentioned the location of wastes and steps to be taken to improve the takt time and production lead time. Implemented line balancing so that the cycle time is approximately close to the expected takt time. Constructed a Future State Map where the supermarket was introduced and improvement opportunities were identified and represented using kaizen bursts. Optimized the process further using various lean tools line bottleneck analysis, continuous flow, waste elimination, kanban, poka yoke, value stream mapping, and 5S. Proposed the future improvements that can be implemented at each work station like complete automation of the processes, SMED, and prepared CAD models. The production lead time was reduced by 59.1% and process lead time was reduced by 65.7%.
