Description
Summary:The suspension design and optimization of Baja car were carried out on the premise of meeting the rules of the race in order to improve the handling stability and ride smoothness of the car. Firstly established the 3 d modelling software UG in suspension system 3 d model, the according to the design of the frame model of hard point ADAMS motion simulation model of motion simulation analysis and optimization selection of parameters, stress suspension system was analyzed by ANSYS, ensure the strength of the car, according to the four-wheel positioning parameters of suspension system and, along with the change of wheel parallel to beat curve using ADAMS/Insight module for parametric curves were optimized. Combined with the design and optimization, the front wheel camber angle changed from 0.81 to 0.68, the caster angle changed from 5.66 to 5.84, the caster angle changed from 6.35 to 6.42, and the front wheel toe angle changed from-1.48 to 0.99, jumping up and down in front wheel track changes reduced from 100 mm to 50 mm, swing arm to connect hard point rise of the front suspension arm Angle smaller, ultimately achieve steering the car light, effectively improve the performance of the car.
