Research and Design on Test System of Motor Vehicle Lateral Stability

The test-system of motor vehicle lateral stability is a special equipment that tests anti-rollover capability of motor vehicle on the specialized slope. Based on the functions that the test-system should have for practical purposes, the design principle of the test-system is analyzed, and it is pointed out that the test-system mainly comprises mechanical platform, hydraulic system, measurement and control system, safety protection device, the critical angle control system and protection system. The key designs are elaborated, such as the overall structural design, mechanical platform design, hydraulic system design, control system design, safety protection device design, etc, ascertaining to comply the design criterions of reliability, safety and convenient operation in design of the test-system. Through the effect of precision on the test-system manufacture cost, the design reference precision values of the test-system are given.
