In this paper, we use 3D modeling software to establish a human body model by combining the data of martial arts movements. Through Newton’s second law of motion force process “isolation method” research, calculate each link of the human body force situation. Using motion capture technology to compare and analyze the standardization of the athletes’ wushu movements, and provide targeted guidance to prevent common patellar strain injuries. A controlled experiment was set up to compare the effects of wushu sports skill enhancement and injury prevention based on mechanics simulation technology and traditional teaching methods. The results showed that the average skill score of the experimental class assisted by mechanics simulation technology was 6.61 points higher than that of the control class, and the rate of individual goal achievement was 0.80-0.92. Only 8 people suffered from patellar strain injuries during the training process, and only 10 major injuries occurred during the season, and more than half of them did not need to undergo surgery. Wushu movement analysis through mechanical simulation can effectively improve athletes’ skills and reduce the risk of injury.
