【摘要】 以4～5 t叉车用双向自增力式制动器为研究对象，基于ADAMS识别和建立制动器部件运动约束，计算并赋予等效转动惯量，柔性化制动蹄和摩擦片等，建立刚柔耦合虚拟样机模型，通过试验验证了模型的准确性。基于制动器刚柔耦合虚拟样机模型，对制动器回位弹簧进行了参数化分析，并根据提出的制动性能评价指标，优化了相关参数，提高了制动器的工作效能。更多还原

【Abstract】 Based on multi-body dynamics analysis software ADAMS, a rigid-flexible coupling virtual prototype model was established for the bidirectional self-reinforcing brake for 4～5 t forklift truck by identifying and establishing the brake component motion constraints,calculating and giving equivalent moment of inertia, flexible brake shoe and friction plate, etc., and the accuracy of the model was verified by experiments. Based on the brake rigid-flexible coupling virtual prototype model, the brake return spring was parameterized, and according to the braking performance evaluation index, the related parameters were optimized to improve the working efficiency of the brake.更多还原
