汽车含气制动液的有效体积弹性模量的研究
Research on effective bulk modulus of brake fluid with air containing in automobile brake system
摘要
Abstract
Bulk modulus is an important parameter of hydraulic system.The containing air in brake fluid has great impact on the stability,stiffness and response time of hydraulic braking system.Therefore,it is necessary to analyze the effective bulk modulus of brake fluid with air containing.This paper analyzed some theory models of effective bulk modulus.Combined with the characteristics of hydraulic brake system,the ideal gas law,Henry's law and the law of mass conservation,we deduced the theory model of effective bulk modulus of brake fluid under the air-compressed and air-dissolved conditions in the braking system.According to this theoretical model,it is obvious that the initial gas content is higher,the effective bulk modulus of brake fluid is smaller.关键词
