Project Overview This project involved the comprehensive analysis of an engine cylinder designed in SolidWorks. The primary objective was to evaluate the structural integrity and dynamic behavior of the cylinder under various operating conditions. Key Tasks and Methods SolidWorks Modeling: The engine cylinder was accurately modeled in SolidWorks, capturing its geometric features and material properties. Static Analysis: Static structural analysis was conducted using ANSYS Workbench to determine the deformation and equivalent stress under static loads, simulating normal operating conditions. Modal Analysis: Modal analysis was performed to identify the natural frequencies and mode shapes of the cylinder. This helped determine the "sweet spot" frequency range to avoid during operation and identify potential resonance issues. Harmonic Analysis: Harmonic analysis was conducted to study the cylinder's response to dynamic loads, such as vibrations and cyclic stresses. This analysis helped evaluate the deformation and equivalent stress under different frequency inputs. Results and Findings Static Analysis: Maximum deformation: 0.789 mm Maximum equivalent stress: 114.2 MPa Modal Analysis: First six mode shapes analyzed First mode shape identified as most critical (frequency: 977.23 Hz) Harmonic Analysis (900-1000 Hz): Maximum deformation at 977.23 Hz: 1.25 mm Maximum equivalent stress at 977.23 Hz: 1617.5 MPa Conclusion The stress analysis revealed that the engine cylinder is structurally sound under static loads. However, the modal analysis identified a critical frequency of 977.23 Hz. Harmonic analysis further confirmed the cylinder's susceptibility to vibration-induced stresses at this frequency.
