Strength Analysis of Motocrosser Frame on Jump-Landing

One of the issues when developing motocrossers is that, when a motocrosser jumps and lands, the landing applies heavy loads on various parts of the bike, particularly the frame, and produces high stresses. This sometimes causes deformation, cracks, breakage, etc. during strength tests on actual bikes, and it takes much time and money to check the effects and develop solutions. To solve this problem, we have developed a method for simulating the jump-landing of motocrossers.
