Explanation and answer, please and thanks 4. In this problem, we design a shock absorber of...
The motion of a car wheel with it suspension (Figure a) can be modeled as shown in Figure b. Determine the amplitude of the wheel X The wheel of mass mw-20 kg, the spring stiffness k-109 Nm and the shock absorber constant C-380 Nism. Assuming that the wheel is moving with a speed of 70 km hr and the road profile is sinusoidal with an amplitude of Y-0.05 m and a wave length L-1.73 m
n as a wheel of mass m, a tire with spring constant kt, a shock with spring 2. (35) Model a suspensio constant ks, and a damper cs. This wheel is subject to an oscillation from the road (eg, rumble strips) of h(t) - H sin or t. All answers use the given symbols. (or depends on the car speed and the wavelength of the road oscillation, but you should just use or.) a) Determine the natural frequency of the...
(40pts) The suspension system for one wheel of a pickup truck is illustrated in the following figure. The mass of the vehicle distributed on this wheel is mi and the mass of the wheel is m2. The suspension spring has a spring constant kı and the tire has a spring constant of k2. The damping constant of the shock absorber is b. Assume the truck's vertical displacement yi(t) is the output and the road surface profile x(t) is the input....
Please help. (3) An automobile running on 4 wheels is about to pass over a speed bump that has a cross section that fits to a sine function of y(x)-5sinßx with B being a constant, and with a maximum width w 8 cm. as illustrated in Figure 1(a). The velocity of the automobile is 20 km/hr at the time of passing over the bump. The vehicle is supported by a suspension system that is consists of one coilover for each...
Consider a single degree of freedom (SDOF) with mass-spring-damper system subjected to harmonic excitation having the following characteristics: Mass, m = 850 kg; stiffness, k = 80 kN/m; damping constant, c = 2000 N.s/m, forcing function amplitude, f0 = 5 N; forcing frequency, ωt = 30 rad/s. (a) Calculate the steady-state response of the system and state whether the system is underdamped, critically damped, or overdamped. (b) What happen to the steady-state response when the damping is increased to 18000 N.s/m? (Hint: Determine...
