Abstract

The dynamic behaviour of a cricket bat significantly influences its overall performance, particularly in relation to ball rebound, power, control, and player comfort. Despite its importance, the relationship between bat structure and dynamic response remains insufficiently understood. This study aims to investigate the modal parameters of a cricket bat, with the goal of enhancing performance and reducing the risk of injury due to repeated impact during gameplay. To achieve this, an integrated approach involving Finite Element analysis (FEA) and Experimental Modal Analysis (EMA) are used to determine modal parameters such as natural frequencies, mode shapes and damping ratios, The FE model of the cricket bat is developed based on the actual dimensions of the physical cricket bat test. Normal modes analysis is then performed using MSC Nastran to compute the natural frequencies and mode shapes of the bat. These results are compared with the EMA results to evaluate the accuracy of the simulated results. The study shows notable differences in modal frequencies, with error ranging from 0.73% to 26.70%. These discrepancies highlight the complexity of reproducing bat dynamics accurately through FE models. The findings of the study indicate that the dynamic behaviour is highly sensitive to material properties, particularly Young’s Modulus and density. This study provides valuable findings on the complex dynamic behaviour of cricket bats. The results can assist players in selecting bats that align with their playing style and support manufacturers in optimising bat performance, enhancing player safety, and improving overall player experience.
