vertical loading การใช้

• The pad used vertical loading common at Guiana, unlike the horizontal loading used at the Baikonur Cosmodrome.
• A feature of a canal aqueduct, in contrast with a road or railway viaduct, is that the vertical loading stresses are virtually constant.
• The frequency content of the suspension movement rate is similar to the frequency content of chassis vertical acceleration and also tire / road vertical loading.
• However, the intrinsic weakness in resisting vertical loading results in the ballast becoming depressed and a heavy maintenance workload is imposed to prevent unacceptable geometrical defects at the joints.
• This was the case in the BMC Mini of 1959 and its many derivatives, where the lower control arm carried no vertical loading, so the joint needed and anti-rattle spring, while the top joint, comprising identical parts, was always in compression due to spring ( rubber cone ) and damper loads, and so was not fitted with a spring.
